CHRISCHRAM  Under Snow Leopard this version of Monolingual does something to its preferences file that causes the application to crash after a number of runs. deleting net.sourceforge.Monolingual.plist and then resetting personal preferences fixes things for awhile, until next time. I just tried locking the preferences to see if I get better mileage. Time will tell.  
(Version 1.4.1)

MORGANG  The text on this download page says it works on Tiger, but after downloading it and trying to run it, I get a message saying it does not work with my OS version. Does it now only work for Leopard and Snow Leopard? Bummer.  
(Version 1.4.1)

CHRISCHRAM  Under Snow Leopard: This version seems to go off to never, neverland about half the times I use it. It barberpoles for a really long time, never finding any language resources to delete. When I finally give up and hit the Cancel button, the application crashes.  
(Version 1.4.1)

ROBERTCOOGAN2  Caused all sorts of problems on my iMac. After running it, it made Safari, Mail, iCal, and Firefox all crash upon launch. Went back into Time Machine and restored the system. Tried running it again, only with the same results. Plus, the second time around Adobe PhotoShop caused (what I think was) a kernel panic twice. The system froze and became unresponsive and the screen dimmed almost like a windowshade was being pulled down.

Best bet: don't install, don't run at all. Unless you are totally committed to removing language files that granted you may not use, but when you consider the size of the files you are dealing with here, it makes little if any difference if you remove them at all.  
(Version 1.4.1)

ACURAICE  I have been using this program for years! Has always worked flawlessly. Not sure why the developer has released this update for Snow Leopard, when I just used this program days ago without any errors, including to remove the additional unnecessary architectures in Snow Leopard with the slightly older version. Not sure exactly whats been updated, but as for being compatible with Snow Leopard, it has been. Keep up the great work! I would have gladly paid for this program and all of your had work.  
(Version 1.4)

TR2  Excellent utility, but my wish list:

a SELECT ALL or

a SELECT ALL except english AND AN OTHER LANGUAG

and i wish that after selecting all i want deleted ONE TIME

would stay like that everytime i launched the program

It's quite redundant to have to add all the checkmarks

time and time again. I'd like the program to remember

the last setup so we didn't have to add check marks

every darned time.   
(Version 1.4)

MITCH_DE  Best Tool to remove not needed language file. It find much, much more than XSLIMER and also its much easier to remove them as XSLIMMER.

I would NOT use Monolingual to remove PPC/Intel Code - that XSLIMMERs work, more safe (Blacklists).

Also check always before STARTING the preferences : remove ONLY foreing languages - NEVER ALL ENGLISH, NEVER yoor LOCAL language.   
(Version 1.4)

THEL  Love the app! However, the min req's stated here seem to be incorrect, as of this latest release. http://monolingual.sourceforge.net/index.php states that version 1.4 "requires at least Mac OS X 10.5 (Leopard) and also works on Mac OS X 10.6 (Snow Leopard). Version 1.3.9 is the last version for Mac OS X 10.4 (Tiger)."  
(Version 1.4)

PHOTOLINKONLINE  Excellent utility, but my wish list:

(Version 1.4)

SNOWWHITESICKETTE  Monolingual works well. I used it to remove some of the junk I don't need that clutters up my hard drive. I ran Monolingual to remove each of the three nuisance types it helps you delete. (Languages, keyboard layouts, and architectures.)

When running languages, I unchecked all English options, but I probably would have been fine just leaving English and US English unchecked. Got rid of all keyboard layouts I'll never need, as well as the Intel binary that just clog up my hard drive. Everything was smooth, fast, and worked perfectly.

I was so happy with the results, I ran Monolingual on two more Macs that day. Each Mac had good results, and for each Mac the process was fast, trouble-free and uneventful. Nice app, but people who don't read instructions before diving in, or who don't know what the keyboard layout or architecture type they are deleting is used for, should tread with caution. (Based on reading some of the comments.) Intel binary is nothing I need running a PPC, and deleting it isn't going to cause a problem. But for Intel Macs, I suggest learning about Rosetta and why you might not want to delete PPC code if you don't know if it serves a purpose. Backing up the disk ahead of time is a good idea.

I believe Monolingual could be used to make a DIY optimized version of an application. For instance, if you have a G3, you can remove the architecture for the G4 and G5, as well as Intel and others. I'm going to try optimizing some of my larger Universal apps and see if it helps. I always back up my hard drive with SuperDuper! before doing anything like this, just in case.

Monolingual saved 180MB on one Mac, 250MB on another, and 750MB on the third Mac I tried it with. I always do a custom install when I install OS X, and leave Additional Languages, Printer Drivers and Additional Fonts unchecked. I think the point updates sneak the languages back into the system, because Monolingual found stuff I know I deliberately did NOT install in the OS.

Monolingual worked as advertised for me, and freed up valuable disk space.   
(Version 1.3.9)

GAMBITZ  Was looking for something affordable and after some digging found this GEM of an app. I've run it on my new MacBook Pro and reclaimed over 2 gigs of HD space. Plan on running it on my other two 3 older machines as well.

A BIG Thank you to the developers for providing such a great utility for free.   
(Version 1.3.9)

KELLVIN  I incidentally deleted the english(u.s) yesterday ,and now I can't type anymore, keyboard disabled. anyway I can go through it?   
(Version 1.3.9)

YUZZ  Very easy to use application, but be careful: know what you are doing or you are in for a lot of trouble! If used correctly, you'll save a couple at least of hundred megabytes of disk space. For me it cleaned up +2GB of space by deleting unnessesary language files!  
(Version 1.3.9)

LSTERN1  I have an 80GB macbook. I ran this program to to free up some space and saved 3.5GB of space! Who knew?

I am not computer savvy but this app. was easy to DL and use. Thanks!  
(Version 1.3.9)

FROSTY  This program will break your copy of MS Office 2008. After you remove the various language packages, it works fine, however, you will not be able to install an MS Office updates thereafter as the installer likes to have all the language packages there. Presumably it installs updates to the various language packages as well, and when it can't find them it pukes out.

I have tried to 'fix' the updaters by following advice from various sites that detail how to override the 'check' so that you can install the updates anyway, however, the result was that MS Word crashes on launch now.

So, use with caution.  
(Version 1.3.9)

OWLY  Excellent piece of software. I just saved 5.3 GB of space (from a total used space of 43 GB) by running this program. I almost bought Xslimmer but I'm glad I found this software first! Thanks so much!  
(Version 1.3.9)

HANDYMAC  One change between v.1.3.7 and 1.3.9 (I haven't seen 1.3.8) is that the Preferences window in 1.3.7 listed only "Directories which contain language files" with the option to uncheck any of them; while v.1.3.9's Preferences also lists directories for Architectures, with System unchecked by default. Thus if v.1.3.9 is run without changing the default settings, it WILL NOT remove PPC architectures from a Universal System on an Intel Mac, which addresses the complaint in recent posts.

As a Mac support tech I set up a lot of older Macs, and find Monolingual very useful for stripping out unneeded materials on smaller hard disks. It may not be for use by rank amateurs, but the ReadMe does cover all the necessary points, and it's not the developer's fault if people don't read it -- or run the utility when they really don't know what they're doing.

CPRAGMAN, the release notes are in the ReadMe.  
(Version 1.3.9)

TRAY STEEL  If you want to remove support for all other languages accept English then just use the following command in the Terminal. You will need to supply admin password.

sudo find / -not -name English.lproj -name "*.lproj" -exec rm -r {} \;  
(Version 1.3.9)

CPRAGMAN  so what changed with this version? There's no release notes.  
(Version 1.3.9)

BIGDAVE56  Firstly, it isn't Monolingual's fault if the user doesn't read the readme file. Agree about the default setting suggestions though.

But architectures aren't the real hogs- language support is. So the only architecture I remove is G3. (I am pretty sure I won't be buying a G3 machine.) The app tells you what architecture your machine has.

On one pass, Monolingual removed one point nine GIGS. Just ran it again after the latest round of Apple updates- space reclaimed 487 MEGS, the equivalent of a complete Microsoft Orifice installation.

I uncheck all versions of English, and Spanish, and remove everything else.

If you have an older Mac with a smaller HD, this app is a must for you. Cleaning out your printers and running this app may save you 3-4GB. If you don't use GarbageBand, then run cleanapp or appzapper, several more gigs for something useful.

No problems with breaking Apple Mail or any other apps here on my G4; however, as usual, YMMV.  
(Version 1.3.8)

JOHN SAWYER CJS  Wow. I haven't used Monolingual for a couple years, but I see that even the latest version, 1.3.8, still has as its defaults, settings that will cause many of the problems that people have been complaining about for years--deleting architectures that are actually needed, etc.

Monolingual's readme file does say "you should not strip the System frameworks if you want to use Rosetta", but I can tell many people don't read the readme file. Even so, Monolingual's defaults shouldn't be set to delete things that the readme file says you shouldn't delete, as if the developer is saying "do my work for me, and change the settings to what they should be". A minor quibble is that I don't understand why the developer switches to using the term "System frameworks" in this part of the readme, about not removing architectures, since some users who don't know the terms, won't automatically know the developer is using somewhat synonymous terms.

I guess the developer knows what he's doing when he runs this app himself, so he assumes his knowledge must be being telepathically transmitted to anyone else who uses it.  
(Version 1.3.8)

ROCHSKIER  Would give zero stars if I could. Completely deletes the MS Entourage conduit with my Palm device and breaks my sync services.  
(Version 1.3.8)

ENCRO  Monolingual 1.3.8 will break Mail.app on Leopard and possibly other code signed applications.

I can manage to consistently break Mail.app and cause it to popup the password window. It will then never remember the password, attempt to store or attempt to retrieve it from the keychain *if the Application code signature is invalid*.

In testing I've tried removing many things from Mail.app such as language files, compressing images, removing redundant unnecessary files and stripping the redundant PowerPC binary and various other things from the bundle. None of this seems to damage Mail.app's code signature.

How do you break Mail.app you ask?

By stripping the debug symbols from Mail.app using one of many app trimming applications such as Monolingual. Since Mac OS X 10.5 Leopard introduced Code Signing and Apple Mail is code signed my guess is that because the bundle is changed and the code signature is then broken and invalid Apple Mail is then treated as an untrusted application and is refused access to the keychain by SecurityServer.

According to

http://developer.apple.com/releasenotes/Security/RN-CodeSigning/index.html

applications should trigger a popup confirmation to allow the Application to update the keychain but it appears that Mail.app does not do this and SecurityServer suppresses the dialog as the code signature is invalid.

I have filed as Apple Bug ID #5734181

Opening Console.app and checking secure.log shows many entries from SecurityServer to advise:

Feb 10 23:04:02 macbookpro com.apple.SecurityServer[20]: suppressing keychain prompt for invalidly signed client /Applications/Mail.app(7514)

Feb 10 23:04:32: --- last message repeated 16 times ---

If you are getting these messages, this wll mean you may need to restore from a backup version of Mail.app from storage, time machine or another computer. If you re-install the app from the original 10.5 Installer CD you may also need to run the 10.5.1 installer and Security Update to ensure that Mail.app is up to date.

DENNISMORIARTY  So can someone answer definitively: Is Monolingual safely functional on Leopard? because the Monolingual website certainly does not specify such. Although this is newly re-added to Macupdate this is not a new version. Thank you.

CHERNANDEZ06  I just ran this program and I didn't see that Intel 64bit was checked to be removed, will that cause any probelms on my mac book, i just bought it today so I want to know if i should reinstall before I put too much on it?

thanks  
(Version 1.3.7)

APPRENTICE SOUNDMAN  Please can someone tell me how to reinstall PPC architure without a total reinstallation ?

I read this thread too late and stripped my PPC architecture, please help

I have a macbookpro 10.4.11

thanks in advance

A.S.  
(Version 1.3.7)

DAVIDSWELT  Folks, do not use the option that allows you to strip PPC code from Universal Binaries to save space on your Intel machine.

This feature is seriously flawed, as it deleted system resources that are important and needed whenever applications are run under Rosetta. In my case, Excel stopped working with certain files, and I couldn't synchronize (hotsync) my Palm any more (it's a PPC application).

I had to manually debug this (Console) reinstall a number of files from my backup (mostly /System/Library/Printers and /System/Library/Extensions and God knows what). This would probably have been too difficult for many users, and they would have had to reinstall OS X.

Until this piece of software has been updated to stay away from /System files, I recommend not using the "strip universal binaries" function.  
(Version 1.3.7)

S_KALB  My Mac isn't able to shut down/reboot since 3 days, and the last major thing I did was using this software.

More unfortunately my Install DVD is in my other location so I will have to wait while this issue keeps angering me everytime I try to shut down !

Suggestion to developer: Add a "Safe Mode" checkbox where ANYTHING too close to the System stays untouched.

Also just a question, is it unsafe to remove English-like (except English) localisations as well ? (UK English, NZ English, Canadian English etc)  
(Version 1.3.7)

MLHOWARD516  I installed this in December of 2006. In August of 2009 Preview quit reading PDF's and Disk Utility was unable to clone my hard drive. I ended up doing an archive and install and then a full erase and install of OS X. I was talking to one of the mac boys (Genius Bar) who delt with my failing logic board and we both had the same problem because of this program. Also, at the time I saved about 2gb. After doing the erase and install and getting all my stuff back on sans monolingual I'm still using the same amount of memory. Definitely not worth it for the 7 months it worked.  
(Version 1.3.7)

YOXI  I've made a request for the option to delete only interface language resources, and leave language tools alone, since it appears (though I can't confirm this) that Monolingual also deletes all the spellchecking dictionaries as well as the interface resources, which I really wasn't expecting.  
(Version 1.3.7)

SNAPMONKEE   Hi! I recently downloaded monolingual.

Removed the input menus/ languages...

Accidentally also removed older architectures Up to g4...bcoz my machine is an intel machine. Now my photoshop CS 2 doesn't work. I 've got a freelance job i got to finish tonite! and i've installed and uninstalled many times, and only photoshop doesn't work. Please help!  
(Version 1.3.7)

PROPELLERHEAD  Agreed.

Don't touch this thing with a ten foot pole.

It seems like a good idea,

But after using it I had to reinstall OS X.

Because all non-intel programs would not work, or would take unbelievabe amounts of time & CPU to launch & run:

all apps from Macromedia, Micro$haft, & Adobe.

Couldn't use any of them.

I support the idea, but I think this app needs a little more work to make it safe.

Oh, BTW those 3 companies need to work a little harder on producing usable software, it's a pity so many of us have to rely on them.  
(Version 1.3.7)

JSTIEL  this program let me choose which languages i wanted to delete then went through all my programs and got rid of them. i saved over 2.5 gb.  
(Version 1.3.7)

BILLEARL  I just requested New Zealand English be added yesterday, and here it is today. That's amazing support!

Great app getting even better with each update!  
(Version 1.3.7)

MACNERD1984  What a great application. I was initially a little concerned about the potential for it causing some problems and did not relish re-installing my OS and all of my apps, but I gave it a go. It sat there for quite a while dilligently scouring various folders for numerous un-necessary language resources and erased them. When it was done I'd saved 2.5GB of HD space. Very welcome since my Boot Camp partition is getting to be rather large.

I've since recommended this to friends and all have had a flawless experience with it. Given this, and the fact that it is free then I can't come upw ith a reason not to give it a full 5 stars. I'm sure that in some configurations it might have the potential to cause an issue but that's pretty much the same with ANY software.

Excellent

JUKI  Can't get v.1.3.6 to download; spends a long time trying to load, then I get either a page saying "file not found", or a page filled with code.

JWENRICK  I installed Monolingual 1.3.5on a QuickSilver 2002 933 MHz running OS X.4.8.

It crashes every time.

Reverted back to ML 1.3.4 and now all is well again.  
(Version 1.3.5)

DALLASKALANI  The aside about protecting the frameworks folder is NO WHERE NEAR adequate. Every non-Universal application needs to be reinstalled after this utility is run. Yes it saves a lot of space, but that is something that needs to be red-flagged BEFORE it happens.  
(Version 1.3.5)

ST00P!D M0NK3Y  Works perfectly. :) I'm using Mac OS 10.4.8 - 800 MHz PowerPC G4 - 768 MB SDRAM.

(Version 1.3.4)

DAJNJ  I am very sorry I used this. After cleaning out everything, many applications will not start up: CopyPaste, Word, Excel, Adobe GoLive CS2...(probably architectures was the problem--I cleaned out all of the PowerPC ones for my MacBook Pro). Any help anyone?  
(Version 1.3.4)

GREG RAVEN  This is certainly a better way of removing localization files than searching for them and then deleting them by hand. However, after running Monolingual on my system, the Spotlight input field is unusable because it is mapped to some utterly alien keyboard arrangement. As far as I can tell, only the "a" key is in the same place it should be. I'm using the Dvorak layout, and everything else seems to be working okay except for Spotlight.  
(Version 1.3.3)

LOKHEED  A predictive space saving report feature would be very welcome. You are notified of how much space you saved after deleting the language/keyboard/arch you selected, but not informed before hand. If possible, it would be helpful to include a feature to report how much space you WILL save before you have deleted anything.

Good program otherwise.  
(Version 1.3.3)

CYANN  Perhaps somebody tells it before, but here's another app doing the same work: "Youpi Optimizer"  
(Version 1.3.3)

TAI  i guess it's not stated clearly, but the three tabs work INDEPENDENTLY, meaning that you can choose to remove languages,inputs or architectures only...

this app is a must-have, but i wouldn't mess with the architectures neither... just remove the languages/inputmenus...

i used to remove them by hand (in the infowindow), but that's very cumbersome...  
(Version 1.3.2)

JETFIREDX  Great app. If you are worried about PowerPC compatibility, uncheck them for removal from the "Architectures" tab. I have used it several times to remove unwanted language files and hasn't caused me a problem yet.

Developer: Perhaps there could be an option to not touch PowerPC code in system files and libraries so that PPC only binaries could still run under Rosetta?  
(Version 1.3.2)

NIAMOR  It save me more than 1,7 Go ! Fantastic !

Ad : the process could be quite long. To make it better you can trash before all the printers plugin from Epson Hp, ect..., you don't need.

Thank to developper ! Great apps.  
(Version 1.3.2)

CHARLESS  This is a great program for deleting needed files and hosing your OS X installation. It's not strictly needed, though, since you could accomplish much the same effect by dragging your /System directory to the Trash and entering the admin password.

In all seriousness, beware of this utility. By default, it removes all architectures other than your machine's native architecture. This means that on an Intel Mac, it will delete all PowerPC code from universal binaries. Now, you might think this would only apply to applications on your system. You'd be wrong. This program will strip the PowerPC code from *all* universal binaries on your system, including all the system libraries and frameworks. The problem with this is that for PowerPC-only apps to run in Rosetta, they *need* the PowerPC code in those libraries and frameworks.

The upshot of this is that THIS APPLICATION WILL PREVENT ROSETTA FROM WORKING AT ALL until you do an Archive and Install.

For this reason, I would recommend against using this highly dangerous app. Messing with the system is a very risky thing to do. Sometimes those "unneeded" files aren't as unneeded as they appeared at first glance...  
(Version 1.3.2)

TOLLINS  I've always used Delocalizer.app in the past, but that hasn't been updated in four years. Glad to see a new app (with more features). However, more documentation regarding Architectures would certainly be helpful. I understand the role they play, but I don't enough about them confidently delete the ones I don't use--which are also difficult for a non-programmer to identify.  
(Version 1.3.2)

MCGUFFIN  monolingual 1.3.2 trips up when it tries to remove architecture from gaslight (the itunes visualiser) and ogrekit framework (part of safaristand?). it doesn't appear to matter what architecture it tries to remove as it always just sits there for hours.

also, i have a g4 powerbook. is it safe to remove the g3 code or is there some kind of backwards compatibility problem?  
(Version 1.3.2)

INGMARSTEIN  If you like this program and want to support its development, you can donate a small amount via SourceForge's donation page at http://sourceforge.net/donate/index.php?group_id=106424  
(Version 1.3.2)

TOMIS  Removed almost 300MB of unneeded architecture data! Very cool.

But the report at the end referred to language files still. Being a programer I realize it's just a minor typo, but if I was your average joe that'd freak me out.  
(Version 1.3.2)

TOMIS  It moved some 41,000+ files to the trash without a hitch.

Unfortunately the MacOS X 10.4.4 Finder is junk, trying to view the Trash caused the Finder to lock up. And after emptying the trash the Finder locked up. What a joke OSX is...

Anyway, it saved me 430MB of useless language files on my 40GB hard drive. Some people might not think that's a big deal, but I do!

And it strips Uni Binaries now too! Sweet!

Still has room for improvement. Would be nice if it..

* calculated the space savings and _then_ ask if I want to trash the files. what if i just want to know how much space all the japanese language files are taking up?

* had derivative languages named as such. instead of "US English" it should say "English (US)", then I can sort by name and easily see all the english types

Other than that, its a solid app.  
(Version 1.3.2)

RIP0FF  Does what it claims and works fine but as you need to know what you are going to do before running it, I won't recommend it to unexperienced users.  
(Version 1.3.2)

HUEVOX  This is really a silly application. Just install and archive. And during the install, also remove the printer software you don't need. I believe the unnecessary printer software amounts to more than the unneeded language software.  
(Version 1.3.2)

COMMANDER LAZENBY  Is it just me, or did Monolingual decide to start ignoring the folders I told it not to touch? On the first runs with 1.3 and 1.3.1, my ignore folders were scanned. I reverted back to 1.2.9 both times and everything was fine.

Also, is it possible that the Architectures scan is infinitely recursing because of the root volume's mount point at /Volumes/Macintosh HD? After 3 hours, I decided to go ahead and cancel the scan. Maybe I should have waited longer...

Still love this software, or at least version 1.2.9.

OUTER  TiPb 500, Tiger 10.4.4, 1G RAM

1) Remove Languages runs forever, at combined CPU utilisation on an otherwise quiet system of 36%, with no apparent disk activity (as viewed from Application Monitor) and no files moved to Trash.

2) Cancelling Remove, and then quitting Monolingual, does NOT kill the underlying Monolingual Helper UNIX(tm) process (had to use Terminal "sudo kill -9 pid). Helper process without parent continues running across sleep.

3) No apparent after effects from 1) and 2).

4) Remove Input Methods works as promised.

ANONYMOUS  Doesn't really seem to work too well on 10.4.1, only seemed to delete Dutch and Finnish even though everything except English and US English were selected, indeed if I do show package contents on things like Mail.app afterwards I find:

French.lproj

German.lproj

Italian.lproj

Japanese.lproj

Spanish.lproj

ko.lproj

no.lproj

pt.lproj

sv.lproj

zh_CN.lproj

zh_TW.lproj

So what was it actually doing ?  
(Version 1.2.9)

FLIP  Freed up 2.3GB for me - using 10.4.1 with a few extra apps. Leaving "US English" unchecked seems like a good idea (for those who wish to use only english)  
(Version 1.2.9)

WILL  A word of warning, the Input Menu deletion function seems to screw things up a bit. I deleted all but English, British and US English. I now have to select Austrian to get the keyboard mapping. It appears it deletes the files, but does not delete the options.

Just now I realized my Z and Y keys are mixed up.  
(Version 1.2.9)

B  I plan on deleting everything but English, US English, Unicode & CentralEuropean(Roman?).

All the instructions I see also say something about not deleting Roman....but it's not visible as a deletable option in Monolingual......is it not provided as a deletable option or is Roman the same as CentralEuropean?  
(Version 1.2.9)

GORDY  Regarding the statement about unckecking languages in the Tiger inastall:

Well, I did that and Mono still cleaned out 128MB of files!

IMPORTANT NOTE FOR US-ENGLISH USERS:

While Mono, by default, has 'English' unchecked, far down on the listing 'US English' is checked for deletion. You might want to uncheck this one too.

ANONYMOUS  The idea is good, but you don't actually need such a utility: just use the Customize button of the Apple Installer when installing Jaguar and Panther.  
(Version 1.2.8)

ANONYMOUS  "I don't know about you, but I use my computer in only one (human) language--English."

i bit of a dodgy statement, methinks

Apart from that... a great app  
(Version 1.2.8)

ANONYMOUS  This is a great utility I use on all our systems at work to reduce filecount and free up a half gig of disk space; new systems are imaged using a disk image we've already run Monolingual on.

It's great- typically takes a drive from 180,000 files or so to about 70-80,000. 100k files! Boggles the mind how much crap is used by localization, something 99% of the userbase never uses.

Has two glaring omissions- the ability to work on a mounted volume instead of only the boot volume (unless I'm missing something, this isn't currently possible). Some sort of way of remembering the last selections would be fantastic.  
(Version 1.2.7)

SANS  Destroy? It just throws out things that you will never use anyway! And it perfectly safe, if you don't touch English. If your hard drive is 30GB and up, you probably would never worry. But if all you have is iBook with 10GB HD - this is very useful application!  
(Version 1.2.7)

JOHN HUXTABLE  Tried it with 10.3 with very limited success - several applications no longer work and Safari was left in Danish (after being in Japanese for a while). All I wanted was it to leave me with English...  
(Version 1.2.6)

RAZEND  I used it to remove every language other than English and Dutch. Works good, but removed some Dutch finder files too, which it shouldn't have done. Now I have to switch to English as main language. And I don't want that......

(Version 1.2.6)

ANONYMOUS  I used this program to delete everything except for US English and English... and when my system rebooted, I was left with a Mac that only had Chinese menus and file names... I'm sure it was something I did... however, I'm just wanring people... it is very easy to mess up your system with programs like this...  
(Version 1.2.6)

JOCKBOY  Just another word of warning to anyone using this app. Although it is useful, I found a number of my extended keyboard keys no longer worked after removing unwanted language files, most irritatingly half the extended numeric keypad and the right hand shift key no longer worked! I had to reinstall all the language pkg's to restore full functionality.  
(Version 1.2.5)

AKIA  WARNING!

I just used this to clean up my system and remove unwanted language files. This worked good so far, but after I went to delete the unwanted keyboard files too, my system would not want to wake up and I had to copy the /System/Library/Keyboard Layouts folder from another OS X Mac to my computer to make it work again.

Just a warning to anyone who wants to use this!  
(Version 1.2.5)

ANONYMOUS  Great program! While it's generally a good idea to customize the installation of your OS to not install unnecessary language files, Apple updates things fairly regularly. When you use Software Update to [for example] upgrade to a higher version of iTunes, that particular method of installation will just reinstall all those unnecessary languages. Plus, there's all those third-party programs out there that have multiple languages. If you don't use them, then who needs them?

I think part of the reason that people are having so many problems with this app is that they don't scroll down to see that there's actually FIVE types of English listed: Australian English, British English, Canadian English, English [no country specified], and U.S. English. I made sure that both English and U.S. English [since, of course, I live in the U.S.] were unchecked.

It seems quite likely that everyone who's had problems with Monolingual probably didn't specify which particular type of English to use. Though I hate blaming the victim... if you didn't scoll through and look at EVERY SINGLE ONE your options before doing something so potentially catastrophic as removing language resources, there honestly isn't anyone to blame but your own impetuous self.

ILGAZ  I bought Aladdin spring cleaning and you should see the real TRASH claiming to do this programs job professionally.

One word, if you don't know what are you doing, it will crash your OS. You should be EXTREMELY cautious about what to select or not. If you are a newbie of OS X, don't even try to use this app.

About me? I am downloading it and will donate to guys who coded it... It will make me feel better as a moron paid $60 to Spring Cleaning crap.

woe is me.  
(Version 1.2.4)

THE MTB  Its always worked great for me. The only problem I have had was because I was a DUMBASK and deleted the wrong keyboard file. My keyboard stopped working.

My suggestion before you delete the input files is go to system>library>Keyboard Layouts and make a copy of that on your desktop. Make sure its named EXACTLY the same thing because if you delete the wrong file you won't be able to type but your mouse will still work. Then all you have to do is drag the folder from your desktop to the library and restart.

DANA SUTTON   I've got 160 mb. on my internal h.d. and another 120 on my external one. I can remember the time when if you told me I'd have that much storage space I'd have said you were insane. These days space is NOT a problem for anybody, and I think the possible damage you can do monkeying with your OS and maybe deleting the wrong thing far outweighs any possible advantage.   
(Version 1.2.4)

GOSTCODER  Unlike previous users, I choose not to remove the keyboard layouts. They only take up 1.1MB of space anyway.

Oddly Monolingual has "US English" checked by default as one of the languages to remove. Yet all other forms of English are NOT checked.

Good thing I looked through the list before I hit remove.  
(Version 1.2.4)

ARTHUR B  testet on new OS 10.33 and old 10.28 - work well without problems!  
(Version 1.2.4)

ANONYMOUS  I'm pretty sure my System is back to normal. The problems I had were:

1) US Keyboard option was GONE despite the fact that I did not remove it.

2) Safari (of all things) was wrecked, would not open new window on startup and opening a new window would not work yet an "Untitled" window would show up in the Window menu. You could select the window and it would appear at that point, but would not load any web pages.

I am not aware of any issues, but there could have easilly been more.

How I fixed it:

1) Had to type my password in the user field by trying every key on keyboard until I found the right combo to enter my password so I could reboot the computer when the restore disk prompted me.

2) Ran my PowerBook restore disk, and selected the option to restore my machine leaving the User/Network settings intact.

3) Safari WAS STILL messed up, so I decided to run Software Update for everything which took quite some time.

That seemed to do it, I'm back on my PowerBook and writing this message from it. Hopefully I won't find any other oddities.

I am done installing useless shit on my Macs. I knew I shouldn't have messed with this thing, but I did it anyway. Lesson learned.

Nice coding MORONS!  
(Version 1.2.4)

ANONYMOUS  he fixed "assorted bugs"? what about the bug (which is the application itself) that renders your system unusable? Great piece of work numb-nuts. you didnt test this out or there wouldnt be all these people having these problems.

Does anyone know how to fix the damage before i do a whole OS reintall? I found the keyboard layouts folder, but its protected via authentication, and since the keyboard doesnt work, I cant type in my password to unlock it and input the delete layouts.  
(Version 1.2.4)

ANONYMOUS  How about writing an application to fix the damage this lousy thing does? Seriously... It is damn near negligent to release such crap on the community, although those of us dumb enough to use this to save 200MB are even dumber. This file should be taken down right away.  
(Version 1.2.4)

PLEASED  This saved me about 500 meg on a PB G3 under 10.3.4! It takes a while but is well worth it. Now I'm wondering if there is a similar way to remove files for some of the printers I don't use.

OHAIRY1  I've used v1.1.2 and 1.2.3 without issue on OS 10.2 through 10.3.3.

1.2.3 is definitely faster than 1.1.2.

C S MOTE  Same problem as others - munched 10.2.8 install. Somethings up when multiple users have the same problem.  
(Version 1.2.3)

REDDOG99  DANGER!!! Use this at your own risk!! I've had to re-install 10.3 on two computers after removing everything but English last night. The computer would only boot half way then stop. And the fun's not over; I need to reinstall everything in Applications and OS 9 won't start either :(  
(Version 1.2.3)

BRIAN KENDIG  I used to be a great fan of Monolingual. But the recent reports here of it eating more than it was supposed to worried me, so I tried Delocalizer instead. I've now thrown away Monolingual, because Delocalizer is MUCH faster (about one minute to run on my iBook/300, versus twenty minutes or more for Monolingual), and it finds and removes more unneeded foreign-language resources than Monolingual did.  
(Version 1.2.3)

WHYTOI  Never again with this program after it erased the English environment in the OS as well as 80% of my apps with 1.2.2. This is despite carefully selecting the various language files. No ideas on how it managed to screw things up. It's just inexcusable. Moving to DeLocalizer and the developer there seemed much more professional.  
(Version 1.2.3)

TOURNESOL  Works great, but this version only uses french language. I can see that english is in the resource folder, but it doesn't seem to load that on my machine.  
(Version 1.2.3)

ITJUSTWORKS  I've used this app since it first came out a couple of years ago, never so much as the slightest problem using it.  
(Version 1.2.1)

RLO  BEWARE - I followed instructions and left the language I wanted to keep unchecked which was English. It then did the opposite and deleted all english files on my iMac. I had to do a reinstall of my system to get it working properly again.  
(Version 1.2.1)

YOXI  Here's an interesting thing.

If you've no plans to use other language interfaces in OSX (i.e. you won't ever want your menus and message boxes etc. in more than one language), but, like me, you still want to write in more than one language, you might want to use Delocalizer rather than Monolingual.

While both apps gets rid of unnecessary .lproj files, Monolingual also ditched the dictionary files for the non-saved languages, so I was no longer able to spellcheck in languages other than the one I kept, British English. I had to reinstall Panther to get them back, and then run Delocalizer to get rid of the unwanted stuff again, whilst preserving the dictionaries.

So if you want to spellcheck in a particular language, either don't let Monolingual touch that language, or use Delocalizer instead.  
(Version 1.2.1)

BAKERMAN2033  Why wouldn't you just go into User Preferences and select "International" deselect the ones you want to use, leaving only "english". ? I left them all on the system, but deselected them .. There was a time when I needed to use Italian, so I went back in selected it, used it for what I needed then de-selected it again... Just a thought ...  
(Version 1.2.1)

E-ONE  Works like a charm on Panther!

Regained about 300 MB of diskspace.

Thnx for the prog, for those of us not so "bright" to think about languages-choices and the space it takes up, before installing OSX.

MARIO LEONTI  When you install Sys X choose customize, deselect any language and/or fonts you do not want and do not put them on your hard disk in the first place. Much better! Ah if only people read manuals :)  
(Version 1.2.1)

ANONYMOUS  My system 10.2.8 began acting very strangely after running Monolingual version 1.2.1 - applications wouldn't start or quit (even force quit), system froze requiring a forced shutdown with the power button.

I never had problems with Monolingual 1.0 or 1.1  
(Version 1.2.1)

ANONYMOUS  I've just spent the whole day reinstalling OS X because of this app.

I unchecked all of the languages I didn't want to be deleted (US English [I think OS X needs this to startup no matter what language you use] and British English) and it then proceeded to deleted those languages.  
(Version 1.2.1)

WHERE EAGLES DARE  This is great. It takes two hours to do that manually. Very stable. Bravo  
(Version 1.2.1)

INGMAR STEIN  @JimW: even if you select only one language in the OS installer, all additional packages which come with the OS (such the iApps) will have all language files installed. Monolingual let's you remove those files along with the localization files from programs you installed after the OS.  
(Version 1.2.1)

JIMW  Comment and Question: Somehow I just don't get this: Apple provides a custom install feature with the OS installer so that you can install only the languages you desire. Why not do it that way and not be concerned over damaging the OS by a removal process?  
(Version 1.2.1)

WHYTOI  Not good. I've used Monolingual since 1.0 or 1.1 stage. No problems until 1.2.1 (bypassed 1.2.0). Despite picking the correct languages and sparing English, Chinese. It screwed up my system language. I could no longer go back to English for my Finder menu. Everything moved across to English. Worse, Safari got turned into some weired Northern European language. Had to reinstall from 10.3 and up. I say avoid this rewrite version and wait...  
(Version 1.2.1)

THE MTB  Seems to work without any problems. It doesn't remember my preferences of which languages to remove and for some reason keeps unchecking Irish, Korean, Chinese and Swedish.

I don't like the scrolling menu at all. I like DeLocalizer's interface much better because you can see all you choices at once. I am glad to see MonoLingual has finally been updated though!  
(Version 1.2)

INGMAR STEIN  Hi, I'm the new maintainer of Monolingual.

About the auto-updating: the version file on Joshua Schrier's website has not yet been updated. I expect this to happen in the next few days...

And about the "one (human) language" comment, I think Joshua meant "human language" as opposed to "computer language" like C, C++, etc :-)  
(Version 1.2)

1EYE  DeLocalizer 1.1 may be a superior alternative.  
(Version 1.2)

JOHN P HUGHES  Whilst I now have an additional 56+ MB of free disk space, I note two issues which need attention:-

1) Auto Update is offering to update the application on every launch!

2) My preferences do not appear to be remembered and have to be re-entered at the start of every session.  
(Version 1.2)

EJI  I kept all major western European languages and English variants (just in case), and still reclaimed 347MB. Excellent app and a cinch to use.

DARTH BROOKS  Thanks, J. Schrier, for this wonderfully useful little piece of freeware. Only a Klingon would not appreciate the humor in your "one (human) language" comment.

NET WATCHER  Excellent application. But I suppose you owe a lot of people an apology by saying, " one (Human) language--English". Do you mean other languages are Non-Human? Watch what you're saying buddy! Are you racese? You might end up in court for this.

ANONYMOUS  Amazing. OS X install so much junk :(  
(Version 1.1.2)

JOEL MADSEN  Does what it says. Very easy to use interface unlike another program I tried. Does not have as much control over individual language files, but unless you just want foreign support for one or two programs, you dont need to go by indivual files. Works well.

down with the USA! (and al other expressions of patriotism & nationalism.

Lol, what a joke to make a fuss about that.

Nice program, does what it says.

i especially like that you have "localized" this program for other languages as well.. ;-)  
(Version 1.1.2)

ANONYMOUS  Give me a break, anonymous. The icon is an exact representation of what the program does, namely trash unneeded localization files. A lot of people are going to use that to trash American English files, so that's just as appropriate as the French and German flags. And he surely had to make a choice, as you can't depict 150 different flags in a small icon. So what's the big deal??? Are you some sort of nationalist?  
(Version 1.1.2)

SETH  works fine, no problems. Reclaim thos .lpoj files that add up to several hundred megs....  
(Version 1.1.2)

ANONYMOUS  No offense to the author of what is surely a well intentioned and useful program, but seeing the american flag go into the trash in the icon kinda rattles me. I'd assume other nationalites included in the icon with their flag going into the trash arent totally thrilled either. Suggest changing the icon, but otherwise thanks for the nice program. I didnt download it, so if its just the picture here on macupdate and not the program icon, please excuse me..just dont like to see flags, especially my own, go into a trash can..but its a free country i live in so the author can do anything he wants if he likes it that way hehe. just a comment. :)
