Monolingual

1.8.212 February 2019

Remove unwanted OS X language resources.

Overview

Monolingual is a program for removing unnecesary language resources from OS X, in order to reclaim several hundred megabytes of disk space. If you use your computer in only one (human) language, you may not need to be taking up space on your hard drive with extraneous localization files. Monolingual will locate and eliminate these space-wasting files.

Monolingual was written by J. Schrier and I. Stein, and is released under the GNU General Public License. Source code is available.

What's new in Monolingual

I have used Monolingual for almost since the inception of OS X. It is one of the most reliable pieces of sw out there. Yes other programers has included the features into their programs but that is just more of a tribute to the original. I have even tried older versions of it and they still run because he stuck to the Apple guidelines. But one word of warning, do not strip the languages from Office 2008. If you do, you will not be able to update it anymore. Why, ask MS those schmuck do things I will never know why. Also be carful when you try to slim down your apps by removing the fat binaries. Some of them WILL not work after you do it & will no longer boot. I had to reload many apps after trying this feature so user beware. I reviewed Monolingual back in 2003 or so and gave it an outstanding review. Over the years it has evolved very nicely and I hope it stays functional for PPC users as well as Intel users. What seems like a minor utility can save gigs just in languages alone if you never ran such a program. I took office 2008 out of my app folder so it would not touch it. One addition would be nice to add in the pref. An exclusion tab where you can tell it what not to touch as it works. To me that is the only thing missing and with the problem of reducing fat binaries well that is the problem with the sw and really not Mono. That is just how the software is designed. If does not see the full pkg it will not load which is a pity and waist of space. One last thing, stability, in all my years of using it it has never crashed in the middle of an operation. It is free so how can you go wrong. End of Line... Note: Robert Lewis is a Freelance writer looking for work.

I tried this today. I ran it in the mode to remove unused architectures. I removed all except the Intel arch's keeping both 64bit and 32bit.

After running a few minutes, the finder froze and I had to restert finder. The dock still was not working right so I rebooted and used AppDelete to remove all of it.

I see in the FAQ that some things should not be touched, but there seems to be no way to disable touching Adobe apps, for example. (At least I do not see it in the preferences.) It would be nice to be able to select one app to see what it does without going thru the entire disk, but that seems not to be an option.

I also notice that even on applications where nothing is removed, it changes the date stamps of the files thus making them have to be re-backed up.

Overall it just seems too dangerous to me for the minimal amount of savings. That said, I am not sure how much it got done because I had to kill it due to the finder issues, but it probably did what it claims to do, otherwise it would be one star. Sorry. (10.13.6 is my OS, 1.8.2 is my version)

Wonder if this app will be redone when they get rid of 32-bit apps so that it works correctly?

You have to go into your security settings to allow installation of the helper utility.

I just installed 1.8.1. The note at the end states, "Files Removed. Space saved: 1.86 TB." That's pretty funny. My SSD is only 256GB. I had it put the removed files in the trash. When Monolingual was done, I had 2MB in the trash. Maybe it should have said, "Space saved: 1.86 MB." Even though we may have a typo, it still does an excellent job removing language files.

i downloaded v1.8.1 from github (the link here wasn't working), rebooted with SIP disabled... and regained about 2GB on my mac (running mojave, latest beta); for some reason, the app showed "2PB"... (whatever the hell that means). but it works!
