ZWILLIAMS  Up until recently I had been a very happy Quicksilver user. But, after updating to this latest version everything is borked. Quicksilver will no longer run for more than two seconds straight without crashing. I've deleted all the associated files and tried reinstalling to no avail. I tried going back to the old ß54 I'm very disappointed, not at the developers but at how this situation is turning out for me. Quicksilver has become an indispensable part of my routine, and this has really slowed me down.

I hope this can be fixed quickly.  
(Version 1.0b57)

TRIAL&ERROR  Here, on a German system, it works for folders, applications and direct access to preference panes.

It isn’t consistent, though: while the selected match (the one displayed in the bezel) is shown with its localized name, the other matches listed below the bezel are shown with their original names. E. g. "Calculator.app" is "Rechner" in German, and it is found correctly when I start typing "Rec...", but in the list below it still shows as "Calculator.app" in "/Applications/Calculator.app", instead of "Rechner" in "/Programme/Rechner".  
(Version 1.0b57)

GYROSCOPE352  For some reason, this build is much slower for me than the last official build (B54). The old build, why it has the obvious issues related to Snow Leopard, is lightning fast, but the new build is slow. There is a very noticeable delay to pop the window up and when I'm typing - I have to type my query and then wait at least a second or two before the text shows up. Any ideas why I'm having this issue? I seem to be the only one; performance was supposed to be improved in this build.  
(Version 1.0b57)

ELLEE H.  Build b54 hasn't given me any trouble but I'm setting up my new iMac and might as well migrate to b57. I'm one of the skim-the-surface users of Quicksilver who nonetheless is paralyzed without it. I hit spacebar left arrow reflexively when I need an app, so no matter where I am, like at the new UWS Apple Store the other night, I'm momentarily confused if nothing happens. Then I think to myself: "oohhhh... no Quicksilver! *I* have to do it." Thank you to all developers of QS.   
(Version 1.0b57)

ZANGADANGA  Who's build is this? There is no mention of it on blacktree.com or in the github profiles of either tiennou or andreberg  
(Version 1.0b57)

FLARK  Ever since leopard, Quicksilver has been unable to find localized folders and applications on my danish version of OSX. This latest update seems to have fixed the issue with folders, however, native applications can only be found by typing their english title. e.g. "Activity monitor" is "aktivitetsovervågning" in danish, but starting to write "akti..." brings up nothing. I have to write "acti..".

This update has brought back hope that QS is not down and out, so I'm really hoping to see this being fixed in a future release. Otherwise, great to see that QS is still being worked on. still one of the most invaluable apps on my mac :)  
(Version 1.0b57)

SBCHAVEL  Double-modifier shortcut to activate interface no longer works. You now must have QS in front for double-modifier to work. Is there something I am missing?  
(Version 1.0b57)

MDOGNRDOG  Quicksilver is not really a supported "product." It is also not one of those typical Mac "it just works" things -- you have to explore how to set up your workflow to exploit the power that Quicksilver possesses, and tinker with settings until you've got it dialed in perfectly.

That being said, I feel CRIPPLED when I accidentally quit Quicksilver, or I'm using a Mac that doesn't have it installed. Apple should hire the developers, and make QS functionality part of the core operating system. Sending files to the proper places, appending text to designated files, attaching files to email, looking up contacts, simple app launching -- these are tasks that would otherwise require several clicks through the Finder hierarchy, sometimes much more than that. But in Quicksilver I'm there in a flash (often with hotkey "triggers" that I've memorized to make it faster still).

The new version, b57, fixes a couple problems that had plagued QS since Alcor, the original developer, abandoned QS to go work on other things. It now runs like a champ.

If you can handle a little tinkering, QS gives you insane, effortless power to get things done. If you can't, don't complain about QS -- it's just not your cup of tea.  
(Version 1.0b57)

NONTROPPO  The most recent source is being developed here:

http://github.com/tiennou/blacktree-alchemy

Note: this builds perfectly in XCode, I'm no developer but I can easily build my own build of QS, very cool!  
(Version 1.0b57)

MARIO ESTRADA  Excellent, now faster than ever.

And works great on Snow Leopard and still free!  
(Version 1.0b57)

MONOENTRENADO  Well, I just can't live without Quicksilver, but in snowleopard it simply don't start, not in my imac, nor in the macbook pro.  
(Version 1.0b57)

FONGD  Indispensible!  
(Version 1.0b57)

TRIAL&ERROR  “Requirements: Mac OS X 10.6 or later” plus “Platform: PPC/Intel” doesn’t make much sense.

Actually, b57 runs fine here on a PowerBook G4 with Mac OS X 10.5.8.  
(Version 1.0b57)

VRH  I love this application! I'm looking forward to when proxy objects (like "Last Command") are working again. :-\  
(Version 1.0b57)

PETERNSTEINMETZ  Had troubles running this new version under 10.6.2.

Threw out the ~/Library/Application Support/Quicksilver folder and ~/Library/Preferences/blacktree.Quicksilver.plist

and now it reinstalls and works.  
(Version 1.0b56a7)

MACHSPEED5  somethings when i invoke quicksilver i get a blank window/box under 10.6.1  
(Version 1.0b56a7)

ICONZ113  Been a long time user of QS, I switched to launchbar when Snow leopard came out because I kept having problems with QS, I just tried again today to use quicksilver, crashed within the first 60seconds, Im officially finished with this thing  
(Version 1.0b56a7)

KRIONI  Strangely, every Modification Date is from June 2009. Have the developers waited 4 months to release something they finished in June, or did the computer they put this together on have a really bad Date setting?

I'm looking forward to using this, but thought that was very strange.  
(Version 1.0b56a7)

DR. GIRLFRIEND  Bye bye Launchbar!

Quicksilver is working just as good as it used to in the good old days. No instability, no system hanging, no crashes like with some of the other previous betas.

And on a more superficial note, I'm elated that I no longer have to look at that ugly orange LB in my dock or my applications folder. And even more elated to save $40.00! (Sorry, ObDev. Little Snitch still rules though and is worth every penny.)

Thanks, Quicksilver Team!  
(Version 1.0b56a7)

NONTROPPO  The FAQ gives lots of useful info for working with the new builds:

ASMEURER  This was quitting on load for me, but I deleted my old ~/Library/Application Support/Quicksilver and ~/Library/Preferences/com.blacktree.Quicksilver.plist folders/files, and it works now.   
(Version 1.0b56a7)

YAPPA  Wow!

I never knew it was broken, or "dead". I'm glad it wasn't ... not for me anyway. Wanted. Needed.

One of the slickest, most unobtrusive, yet on-demand pieces of software I've ever used.

I've been using Quicksilver β54 (3815) since it was disseminated. I'm on 10.6.1 now. No problems here. Obviously I'm not using the plugins (etc.) that some others are. It's just an instant launcher for me.

Gives me the sort of access I want to my /3rd Party/Applications ... and ../Games, ../Utilities, etc.

Phew.  
(Version 1.0b56a7)

SEAN8  i am happy to see this updated for 10.6 . . . unfortunately, i've already made the switch to Google Quick Search Box and it's working just swell for me.  
(Version 1.0b56a7)

MABOROSHI  Hurrah! An update!

But shouldn't you guys drop the PPC platform? If this requires 10.6+ its gonna be Intel only isn't it?  
(Version 1.0b56a7)

SHOCK J  Hallelujah!!!! Quicksilver is alive and updated!!! This is my all time favorite most useful Mac utility. May it live forever and we shall all praise it's glory!!  
(Version 1.0b56a7)

DR. GIRLFRIEND  How awesome is it to see a new stable version of Quicksilver back on Macupdate? A big "Thanks!" to all of you brave beta testers who never gave up on it and the current developers for keeping it alive.

Can't wait to try this version.  
(Version 1.0b56a7)

ICONZ113  QS is dead, plugins dont work, and its only gonna get worse. I loved QS but im done trying to tweek it to get it to work. the original developer even said to move on.   
(Version 1.0b56a7)

NONTROPPO  b56a7 works brilliantly for me on Snow Leopard 10.6.1. The core plugins all work well. The only one I was missing was file tagging plugin, but recently an OpenMeta plugin has been added which is far better than the old &comment tag method, and interoperable with lots of new metadata management apps on OS X. The display of characters in the triggers dialogs is broken, but triggers themselves work fine; this is just a cosmetic annoyance.

Quicksilver, even in its opensource community guise, is still significantly more powerful and elegant than Google's QSB or Launchbar.

Openmeta plugin available here: http://groups.google.com/group/blacktree-quicksilver/browse_thread/thread/df03c483786ca2da/  
(Version 1.0b56a7)

AIMEDIA  Latest build seems to work for basic function just fine in 10.6.1. Regarding plugins, those are another game altogether. It is still MUCH faster then Spotlight.

Launchbar may be an alternative, but Quicksilver works fine for my needs, free.  
(Version 1.0b54)

ICONZ113  I used to love QS but to use it in Snow Leopard you have to install the updated build where half the plugins are broken, its buggy, clipboard just appears at random, crashes even when I disable the plugins. I have just come to realize that this application is deteriorating and its only going to get worse as time goes on. To add insult to injury the original developer in an interview suggested it would be better to use something else instead. So Im taking his advice and decided to go with launchbar for now to see how it is. Hopefully with QS dead another application will emerge to take its place.  
(Version 1.0b54)

KZX72  Latest build: http://code.google.com/p/blacktree-alchemy/downloads/list  
(Version 1.0b54)

ROBERT  I'm rediscovering Quicksilver after using it for years mostly as a launcher and Address Book interface. Doing more things immediately on the keyboard in its Bezel interface that I used to do by switching applications and to a mouse and back.

And I'm still amazed by it and finding out what I can do. Best interface contribution to computing since the mouse.

To answer some questions here, Quicksilver went open-source about a year ago. There is continued maintenance of Quicksilver b5X, and the start of something new (Google Code braintree-alchemy). This version on MacUpdate may still be what you want to use for the time being, if you're not having troubles.

For more info, google last year's interview on lifehacker. To improve performance, google Quicksilver Performance Issues on the Mac. To learn how to use QS better, check Dan Dickinson's intermediate Quicksilver tutorial.  
(Version 1.0b54)

SHANE C SMITH  Is this still under development? No update in a year, I think I'm switching to LaunchBar

KAPPE  the compressed file seems corrupted  
(Version 1.0b54)

BSNL555  good thing  
(Version 1.0b54)

FONIK  Yet another glowing review for Quicksilver. I give ease of use a 4 instead of a 5, but only because accidentally mashing keys that include the trigger can lead to all kinds of bizarre stuff. :D  
(Version 1.0b54)

FARCALLER  This application is one of the "must have" apps on MacOS. Seriously, I'm not sure how I would return to Linux without something like QS.  
(Version 1.0b54)

JPBADGER  Wonderful tool that has changed the way I work with files and applications. It is one of the first apps I will install on a new Mac. The plugins are great, some of which I didn't realize I would be using so much.

It may be daunting for some new users, as it is a different way of working. Forget a crowded dock or desktop, move and access your stuff with QS!  
(Version 1.0b54)

THE X  Can't begin to explain how much Quicksilver helps me! It's extremely fast and efficient, very good-looking, has a billion of uses, but still is incredibly easy to use!  
(Version 1.0b54)

THE V  QuickSilver is a must for me at home and at work. It has increased my efficiency radically and makes for a 'must have' in my book.

Quicksilver will hereafter be referred to as QS.

QS is very expandable. There are plugins for a number of applications. From email plugins and terminal plugins to note taking, scheduling and even interaction with other devices. I give QS a 5 for features.

Ease of use... QS is easy to use, but as it uses text input some users may find it may take a little time getting used to. There are plenty of how-tos available online however and it's still intuitive and easy to get the hang of. A four on ease of use.

Value... QS is free. And it has made my day extremely much more efficient. 5. Donate if you can, this is an awesome piece of software!

Stability:

QS by itself is very very stable. I have encountered some issues with a bluetooth plugin still in beta. But these issues are few and far between.

I would give QS a five for stability, and the bluetooth plugin a three or a two. As the plugin is beta however - and not installed as default - I will stick to giving QS a five for stability.  
(Version 1.0b54)

ELEGRAPHY  I have discover Quicksilver caused the window-only screenshot key combination not functioning. (Hold down Command-Shift-4, click the once, then click the mouse key to take the screenshot.)

When Quicksilver activated, it would let the combination keys selected the whole screen area, instead of the particular selected open window. Disable Quicksilver would correct the problem and let the window-only screenshot functioning again.   
(Version 1.0b54)

MACLOVIN  Best application ever, and the library of plugins makes it get better and better. Those of you who think it's simply an application launcher or think that Butler can compete should probably take another look.  
(Version 1.0b54)

DANIEL SCHLAUG  The greatest.

You go make greater things Alcor! Just keep us updated so we can experience them. Spectacular!  
(Version 1.0b54)

APPLEHC  Must have! I am very afraid that developemtn will stop in near futures as mentioned by the developer. Would pay/donate $$ if neccesary.   
(Version 1.0b54)

IPOE  the greatest app for my machines - should be a must for every installation per default!!

thank you very much for your work and this great tool

ipoe  
(Version 1.0b54)

CLAKES  Yay!

Much of a welcome update. I was honestly a little disappointed by the non-transparent-as-should-be lists.

And the update from within the application is working again. Thank you.

Quicksilver is the best. Keep acting without doing! =)  
(Version 1.0b54)

DAVERMONT  The Release Notes available from the Q menu say:

Release Notes: Quicksilver Build 3808

Changes

Corrects some visual glitches on Leopard

Fixes shelf/clipboard behavior in Leopard

Fixes For Plug-ins and App update  
(Version 1.0b54)

COPILOTO  I don't know why this is, but my copy of Quicksilver, downloaded from the Blacktree website says it is version 54. Is this a recent upgrade?  
(Version 1.0b53)

FIENDINC  Don't lose hope just yet! The plugins were apparently taken down barely before Leopard was released, apparently due to speculation of security holes in certain plugins.

Since the release of leopard, after 3 days I successfully installed the 7 core plugins that QS normally offers to optionally install. The QS plugin framework is still out there, so if you have programming experience and have enjoyed the godly role this program gives over your computer, please help in any way you can

The first thing that needs to be done is to build an alternate plugin site....  
(Version 1.0b52)

KAPPABEAR  I love QS, and have been using it for quite a while. Unfortunately, I've recently learned that it doesn't play well with Leopard. During the initial installation, when you're prompted for which plugins you want to load, after selecting them and after selecting them, they don't install. QS plugin installer hangs right there, not doing anything. The program continues to run in the background, as you can click Continue, and it does, but you can't use any of the plugins. I also tried going into the plugin section of the program and trying to install them there, and encountered the same exact issue.

Hopefully this will be fixed, but I doubt it, as the program hasn't been updated in over a year. Ugh ... time to find a new Launcher.  
(Version 1.0b51)

ZWEI  First thing I download to a freshly installed system. Gotta have it!  
(Version 1.0b51)

SIMICHAVEL  Ditto that maclover. My QS frequently ceases responding to the keystroke activator and lies dormant. Only quitting and relaunching gets it going again. Hoping this problem gets resolved.

MACNEWS  Will QuickSilver allow System-owned searches?  
(Version 1.0b51)

MACLOVER1.1  My Quicksilver crashes quite a bit on my MacPro... any update coming up or has this killer app been left as roadkill ?  
(Version 1.0b51)

J.AILEY  I have been using Quicksilver for quite some time. Currently I am using 1.0b51.

Quicksilver is one of those apps that I could not live without. After a fresh install of OSX, Quicksilver is the first app that I install on my Mac.

It makes navigating and using my Mac SO much easier. Running other programs with just a few keystrokes is awesome!

I haven't even began to unlock the full potential of Quicksilver. All the different modules you can load or not load makes this really great.

It is much faster for launching apps than Spotlight and it can be set up to feel as though it is part of the OS. No dock icon, no menubar icon. All you have to do is hit the keystroke, and there it is! Ready to serve.

Give Quicksilver a try, you won't want to use a mac without it again.  
(Version 1.0b51)

GETSOMESAUCE  Is this program even under development anymore?  
(Version 1.0b51)

SNOW  This does seem to take a lot of RAM, although I have liked and used this for a long time.  
(Version 1.0b51)

GIAMBA  Somehow it really slow to load,

and make my computer fan become louder every time I use QS.

in some case it uses most of my RAM, then crashes.

Cataloging my Library folder is still not solved the problem.

So I throw it away.   
(Version 1.0b51)

QUIIICK  Can't open the .dmg-file (QS.3800.dmg)  
(Version 1.0b51)

YOMCAT  I recently told Quicksilver to catalogue my Library folder. Now, whenever I open Quicksilver, it uses most of my RAM, then crashes.  
(Version 1.0b51)

BLUEFISH  I love this app. That being said it appears that there is a well documented bug when using this version on intel macs.

One serious address book conflict or incompatibility... that manifests itself in a varity of different forms from losing all of your address book data to in my case I lose the ability to drop drag files in my finder and the quicksilver menu becomes corrupted (like the font is bad).

I hope that the developer is reading this list because it really is a great application... one that I have grown to rely on in a very short time.

MACGRUDER  This is an extraordinary piece of software. Beautiful free and fast. It has a slightly steep learning curve but give it time and you'll change the way you work.

For example,

You can select an image,

Resize it as a copy,

Rename it,

Choose a name of someone in your address book,

Attach it,

Mail it.

All in about 10 seconds (really 10 seconds) without leaving the keyboard.

Type a number, and it automatically can rate the present iTunes track to that number.

HAUNTEDTAPEDECK  Latest version crashes on startup for me, running 10.4.8.   
(Version 1.0b51)

B.NANIS  Would like to retract my remarks about Quicksilver. Have recently discovered that the reason for the application constantly quitting was faulty ram.

Apologies if my comments mislead anyone.

Quicksilver is quite an extraordinary product.  
(Version 1.0b51)

B.NANIS  How can anyone promote this product without mentioning the ridiculous number of times it crashes everyday. I have been using it for a few months and recently used Appzapper to blow it away.

Since installing this piece of work (quicksilver), many other applications also started mysteriously crashing. Suspect the clipboard plugin was responsible.

Beware the clipboard plugin!!

I do not have many funky things installed on my machine and I am using a Macbook pro with one gig ram.

I will check out Launchbar.

Quicksilver is a great application but hopelessly bugged at the moment.

I will give it another look once it is 'really' ready for market.  
(Version 1.0b51)

CED  I already donnated. I consider doing it again. The developer is a Genius...  
(Version 1.0b50)

JDAN  Excellent app. but I do have problems with the Clipboard module. Sometimes Quicksilver hangs when used in combination with Word or Excel.  
(Version 1.0b50)

SIDETRACKED  Yes, it takes a few minutes of reading the instructions, and a few more minutes of experimenting to get the hang of it. And it gets easier the more you use it - both because you learn it's fine points, and it learns yours (like what abreviations you use for an app or file)

But before long it's all second nature, and fun to use. And this is coming from a cranky old guy who's far from a computer whiz.

I compared it with Butler (which I found less intuitive and more annoying) and Launch Bar (more limited and not free). Subjective reactions to be sure. Both are excellent in their own ways, but this was the one I stayed with.

For those who want a compromise - something simpler than Quicksilver to learn and use, but still free and fast at opening apps and documents, ABC Launch is quite good. A lot fewer bells, whisteles and options, but faster to become second nature.

But for me, I like the fun of the constant development and additions, and the fact that I'm always finding new ways to make Quicksilver work even better for me.

(Version 1.0b49)

AQUILLES10  Amazing software. I feel lost when I work on a Mac wihout it. It's become essential for me. And you can't beat the price either!  
(Version 1.0b49)

KENARONI  I'm using Quicksilver on an old 400mhz Mac G4, and it's plenty fast. Goes without saying it's *very* fast on my G5 at work. And it has crashed on me maybe twice in the last 6 months - usually when I'm trying to send it too many commands at once with my fast fingers.

If it's running slow for you, see if you cataloged to many huge directories, things like system folders. Just catalog the folders you normally use.

I've been using QS for a couple of years, but only lately am realizing all the things it can do. I've been learning a new feature every week that I never knew about before.

Seek out tutorials on the web written by other users. QS is like becoming a Jedi Master - you must have patience and persistence, and you will be rewarded, young Jedi :)

MACLOVER1.1  This is like er... Butler on steroids :-) A little less straighforward at first but once you've scratched the surface you'll see it is very powerful !!!!!!!!!!!!!!! Like a visually non-invasive hub for file manipulation. If you are a true MacUser you've got to at least try it !!!!!!!!!!  
(Version 1.0b49)

ROB  This is an essential os x software.

A must!  
(Version 1.0b49)

SMKSENSEI  Quicksilver has *never* crashed for me and I've used it for a long time. It keeps getting better and has spoiled me tremendously. My number one gripe on the Windows PC I am forced to use for work is the absence of QuickSilver! (Number 2 is no Expose!)

I am constantly learning new uses for QuickSilver. It's one of those apps that make my PC-using friends drool.  
(Version 1.0b49)

THOTH  Quicksilver is really an amazing application and is almost there in terms of implementation. But it has two flaws that are real deal-breakers. One, it's too crashy. Two, and more importantly, it's too slow. The slowness can sometimes be phenomenal, on a quad-core 2.5 GHz PPC with 8GB RAM. I don't care to find out what it'd be like on a slower machine.

Quicksilver has an open plug-in architecture, which is a great idea. But the documentation for these plug-ins is hard to find; I have never found it. Do I blame Quicksilver for the failures of the plug-ins? Well, partly, yes. An end-user perceives it all as one system, and it can be hard to figure out. The real way to figure out these issues is to visit the forums.

I like QS a lot, I think it has a great deal of potential, and one day I might switch back, for now I am using Butler. I find that app to be quite fast and efficient. It's only taking up 126 MB of RAM on my machine, whereas on my laptop, QS is using 262 -- and I expect that to go up over time.

Verdict: QS is a great program but it needs TLC with a view to fixing crashiness, speeding up the app greatly, and using system resources more gently, before it will be the top choice.  
(Version 1.0b48)

~HELL  I simply couldn't work without Quicksilver any more. At first I did not really grasp the main idea behind it apart from being a launcher app. But as I dug deeper into its functionality, I barely work without touching Quicksilver every couple of minutes to find, launch, play, move, copy, whatever anything.

Excellent software! This shows why the Mac is so great.  
(Version 1.0b48)

JROSSOL  Has anyone tried running this on an INTEL machine?

Perhaps the developer could comment on whether he/she plans on making a universal binary.

I use this app more than anything else on my computer and I want to make sure it will still be available should I choose to upgrade!!!  
(Version 1.0b48)

AMSONX  Quicksilver is the best utlity for the macosx , i think taht apple can include them by default in macosx   
(Version 1.0b48)

APFHEX  At first glance I didn't fully understand the functionality of Quicksilver and so I never really used it. But once I gave it a real, long try, I really liked it. As an application launcher it's awesome, but it also does other things. I use Triggers to control iTunes VIA hotkeys. Integrates with Growl which is just great. Lots of customizability. Takes a little while to setup when you first launch it, but it's smooth sailing from there.  
(Version 1.0b48)

TREACLE  It's an impressive programme, but after several try-outs over a couple of years, I've decided this definitely isn't for me. It takes three times as long to launch an application as, say, F10 LS, or even DragThing.

The trouble is I like to use the mouse whenever possible (particularly now I'm forced to work in English on a French keyboard...) and this is an app. for people who are much cleverer than me and use the keyboard for nearly everything.

Great app., well supported, but no use at all to us mouse-users.  
(Version 1.0b48)

MACSTERDAM  Yes, Quicksilver is without a doubt nothing short of amazing! But please, fix it's speed. Just try Launchbar for a minute and then switch back to Quicksilver. It's like trading in a Ferrari for a bicycle. Other than that, no complaints!  
(Version 1.0b48)

HAPLO  Although the occasional beta will crash and not come back till you update or revert, this is probably the single most useful application ever developed for OSX. As an application launcher, it's the fastest and most effective I've ever used on any platform. I used to use it to control iTunes (although that's only good if you actually know the artist/name of the song you want to listen to next) and it was great for that too. It's especially good for programs you use occasionally or even a lot, but don't want to put on the dock. It's really even faster than the dock, so I use it for things I put on the dock, too, on the occasion.  
(Version 1.0b48)

SKIMPSON  QS is simply the best thing on OS X! yes it does have a less than instant learning curve, probably like 10mins, but thats simply bkz of how much it can freakin do! seriously, give it a chance. and for those who say its not updated enough try changing your update settings to "Development Version" then you will get an update every couple of days it seems!

BMEGUY  This is one of the most used pieces of software on my machine. If you only use it as an application launcher, it's worth it. (but to be honest I've never tried Butler or Lauchbar, both of which seem to have very loyal user bases.)

However, it can really be so much more, if you're trying it out (or even using it regularly as just a laucher) try out these functions:

clipboard history

shelf module

append to file...

open URL

process text with your own Applescript

move files around on your system  
(Version 1.0b47)

MANNYMIX03  works really good, the interface is clear and easy to use. The only thing is that if you use spotlight and most your programs are in the dock then there is really no use for it.  
(Version 1.0b46)

MACSTERDAM  This is an outstanding little program, with amazing features. However, I switched back to Launchbar because of speed issues. QS is waaaaay slower than Launchbar unfortunately, which is a shame as it beat Launchbar in any other area.

Still, if speed is not an issue, you should get this!  
(Version 1.0b46)

NSTANOSHECK  If you are not downloading the latest version, use the update feature. It updated mine to ß46. Definite improvements! This is even faster than Spotlight!  
(Version 1.0b46)

MATTHEW  It quit half way through it's initial set-up and now just quits whenever I try and open it. Prefs deletion etc. fixed temporarily but once the set up was completed it once again quits upon launch. I'm on a Dual G5 2GHz, 10.4.3, 1.5GB RAM.

Would like to try it but so far I can only give it a big fat zero..... :(

BENE GESSERIT WITCH  Quicksilver has changed my computing experience. I would not switch from OS X to any other platform because of it. Without QS I don't know what I'd do, probably read a book. It is so flexible, extendable, responsive, intuitive. I used to use Launchbore and took a look at Buttler, but QS is by far the best, and a great user group community! Can you tell I've had too much sake? But anyway what I say holds. It will change your wife.   
(Version 1.0b45)

ZWEI  Quicksilver is one of the best free apps available. I only use a small portion of it's functionality (app launcher and triggers), but that functionality along with a seriously sexy interface and a KILLER update mechanism make this app a must have.  
(Version 1.0b45)

MACD  I used to use QuickSilver for a long time, ever since it has been out. But now I am completely switched to Butler. The reason? Well, Quicksilver is a gem in user interface area, but when you need a fast launcher, the word "fast" goes before "beautiful UI", and that's where Quicksilver still has to catch up with Butler. Both are.. fast, not that Quicksilver is slow, but Butler usually comes up with its window perceptually at least twice as fast, when Quicksilver starts scratching my hard disk looking for something, or reviving itself from swap, or.. I don't know.

I really wish Quicksilver would become fast (and no.. turning off all the visual bells&whistles doesn't help a bit), but not Butler is a way to go for me (although a bit cumbersome at configuration, and also not with as pretty interface as QS).

Speed, please!

FRANK H. WU  I loved earlier versions of this program. It runs perfectly on my PowerBook with Tiger, and I must use it hundreds of times every day. But for some reason on my iMac also with Tiger, it suddenly stopped working -- even an uninstall and reinstall didn't fix it. Not sure whether it's an issue with Tiger or something else, but in any event the program is still terrific on the PB.

ANONYMOUS  Seems Quicksilver still has the sleep bug from the 10.3 version. You open Qucksilver, sleep your mac overnight, and wake up sans QS. Other than that, it's a great addition to Spotlight(QS does local user-set searches and Spotlight does global searches).  
(Version 1.0b42)

KERRY CONNOR  Can someone please tell me how to get my QS to look like the screenshot below? I'm not sure if I'm just not using it right or what, but when I use it, it just has a browsing and action field. I've seen several screenshots like below and am not sure how to use it like that. Thank you!  
(Version 1.0b42)

ANONYMOUS  Quick Silver is an evolving system - supporting plugins, so you can say search though your bookmarks, contacts, display phone numbers in giant text etc all from the key board. Spot light is aimed at finding documents, or contents of documents. I think of quick silver as a way of pulling things out of the dock, that I may use often, but do not want to clutter the dock with.

It is very fast for basic search, ie Applications Folder. If you are looking for an application that will find documents, perhaps launcher or spotlight is better.

Very nice User Interface.

Keep up the great work!  
(Version 1.0b42)

ANONYMOUS  Why Launchbar is better than Quicksilver, part 133:

Install Launchbar, activate it, type "tm". Launchbar finds and highlights TextMate, ready for launching.

Install Quicksilver, activate it, type "tm". Quicksilver finds the freaking HTMLRendering.framework from 10.1 that I haven't used in years, on another volume! TextMate may have been listed, but I wasn't about to scroll through all 155 matches looking for it. QS may get better with training, but I really can't be bothered if it's so stupid to begin with.

Worthless.

MRANDRE  I hate using computers that don't have QS on them. Without it, a computer is reduced to a bit-pedaling pile of silicon. With QS, a computer becomes a helper that comes when I call, gives me exactly what I want, and disappears. I only wish more things in life were so well designed and implemented.

Note: Those who say spotlight obviates the need for QuickSilver are smoking the world's finest crack. Addicts: Find these people; they have the goods.  
(Version 1.0b42)

ANONYMOUS  It's unbelievable to me that Apple hasn't yet either copied this program, or asked its developer to help them make it built-in to the OS.

Hands down, the most useful application for MacOS X.  
(Version 1.0b42)

BRILDENLANCH  I have no such problems. And Spotlight and Launchbar making QS redundant is the stupidest thing I've ever heard.  
(Version 1.0b41)

PAUL  It is easy to see why people have their differences about this product because of its unusual nature. A first impression might be that it is obscure and not all that useful, but the reality is that it takes a little effort to get it configured and working in a way that is useful to the individual.

It could be an issue with the current version, but I could not understand why my documents were not being accessed, untill I looked in the preferences and found that only level 1 of my documents folder was cataloged and that it was not possible to change this. I'm assuming this is a bug because it makes not sense. To get around this, I added my documents, and my classic folder as a custom catalog and the program began to get a lot more useful to me.

So, if you are trying this application for the first time, give it chance. In collaboration with spotlight and a few other tools, it should make your life easier. Provided you can get it configured to your liking.

MICHAEL WEISSER  an awesome piece of software! TRY IT!!!

it's not only a great software it's a new (much easier) style of how to work with your computer...

FANTASIC WORK - MANY THANKS  
(Version 1.0b41)

DOUG  I've been using Quicksilver for almost a year now, and people seem to either love it or hate it. If they just don't 'get it', they tend to hate it. My advice to these people is to take a few minutes and give it a chance!

Go here: http://vjarmy.com/archives/2004/03/quicksilver_a_b.php

for a 10 MINUTE tutorial -- kind of old, but helps you get the idea.

It's been BETA software as long as I've been using it, and I've only had a few minor issues.

THIS is the feature that the Finder has been missing all these years! I'd almost give up a command line in leiu of QS functionality.  
(Version 1.0b41)

SCOTT FANNEN  Quicksilver is probably one of the most practical utilities for Mac OS X. When used to its best advantage (and it is far from obvious how to), you'll find yourself getting irritated when it takes more than a few keystrokes to find a friend, a file, a song, or a photo.

Spotlight doesn't replace this (Spotlight doesn't "learn" from your selections for a start) but is something that will augment it.

b40 and above try to use the new technologies introduced with Tiger and there may me a few teething problems (especially getting all the favourite plug-ins updated) but it still is great. It's also currently free so what's to complain about.  
(Version 1.0b41)

GARBAGE  I tried quicksilver in the past. I was impressed by it's ambitiitous design concept but frustrated by it's overwhelming feature set. I stopped using it.

Since installing 10.4 I am a big fan of spotlight because it finds documents & launches applications real quick with a minimum of trouble to the user (me).

IMHO only a small subset are going to want what quicksilver offers.

It will be interesting to note how the developers of QS respond to the challenege...  
(Version 1.0b41)

ANONYMOUS  No better than it ever was. I was hoping the Tiger-only version would leverage Spotlight's metadata, Core Data, or something so it wouldn't prefer Safari bookmarks and Address Book entries to applications I'm trying to launch. Alas, it still insists on doing so, no matter how much I try to 'train' it.

Spotlight + Launchbar makes QS more than redundant.  
(Version 1.0b41)

MRANDRE  Attention Tiger users: Spotlight is not, I repeat, is _not_ a replacement for QuickSilver. It's a watered down version of some of the functionality. Spotlight finds thnigs and opens them. QuickSilver finds, opens, moves, copies, emails, IM's, and accesses many data structures spotlight does not. Don't get me wrong, spotlight is great for what it is. But putting it in the same league as QS is simply wrong.   
(Version 1.0b41)

JCHRYSS  I used the program extensively in panther and loved it. I no longer use it since I installed Tiger. Thanks to the developers for filling a niche before Apple, but I don't need this anymore since I have Tiger. As paris Hilton would say "Spotlight is hot, quicksilver is not hot"  
(Version 1.0b41)

STU WILLIS  b36 was only released last week and is the latest version for Panther. b40 introduces a whole range of new features which -depend- on core Tiger technologies. so if you're upset you can't use this with panther, get b36 from the developer's website.

after all, can we really complain when a program this good is released for free? AND is being developed aggressively.

(Version 1.0b40)

ANONYMOUS  Well i got tiger yesterday and I cant say i will stop using quicksilver as searchlight is more of a search and it does'nt find applications as fast as quicksilver.

I might use searchlight to find files but il definatly keep quicksilver as my favorite launcher  
(Version 1.0b40)

ANONYMOUS  I do believe in taking advantage of what new technologies offer however I find the restriction to the only OS version that has a compiting solution already embedded quite risky.

Quicksilver has been a really useful tool and it would be a shame seeing all this work fading away because of debatable choices.

At this point though there's no point in complaining. Just sit tight and see what happens.

It can be one's "go to" function for easily accessing all of one's files and apps. Easier, more intuitive and faster than anytthing I have ever used before. You will not regret trying this out.

If you are still on Panther, remember to download any older version than the one currently listed above.

CAFFEINE  I like this app except i found 2 bugs in it.

1 - If I put my mac to sleep and is re-awakened, Quicksilver is no longer running. Its as if it quit while my mac was asleep.

2. It can't properly make apps run as root because when Quicksilver tries, the app just bounces for a seconds or 2 then goes away.

Those are the only 2 problems I have found so far.

BRNRDRGN  You can do almost anything in Quicksilver(run apps as root, set desktop pix, play tracks in iTunes, etc.). And it learns from your user habits to modify itself and be faster for you.

Why Dragthing is less than zero - too many open processes

Launchbar? Never heard of it.

And it's free. Are Lunchbar(sic) and Dragthing free?  
(Version 1.0b35)

ANONYMOUS  In many user interface studies they always find two pertinent facts:

• Test subjects consistently report that keyboarding is faster than mousing.

• The stopwatch consistently proves mousing is faster than keyboarding.

This contradiction between user-experience and reality apparently forms the basis for many user/developers’ belief that the keyboard is *always* faster, and Quicksilver (and LaunchBar for that matter) symbolize that phenomenon. Now, I gave Quicksilver (as well as LaunchBar) a serious try, and I found out that while they both worked okay as a quick search tool it wasn't even close to becoming a true "cure all" launcher as many advocates seem to claim these days.

The keyboard shortcut of any sort is useful and effective when the user can select with one hand on the keyboard and act with the other with the mouse. Two-handed input can result in solid productivity gains, but "Do-It-All-on-Keyboard" can be quite opposite of that, and I am afraid Quicksilver is a prime example.

I agree with the previous reviewer on QS being a bloatware. Quicksilver is trying to do way too much. Even used strictly as a quick search tool LaunchBar was still far better in guessing the right object for my abbreviation.

I would also like to note that, quite contrary to what some other reviewers mention, Tiger's Spotlight is NOT quite the same thing as Quicksilver or LaunchBar. Spotlight goes way beyond that, it is able to work with file contents beyond just metadata, while Quicksilver and LaunchBar mainly works with file names.

Overall, I was quite unimpressed, and as the previous reviewer say, I couldn't see what the big deal was about this software. There are other "Find file" type tools that are better than Quicksilver/LaunchBar, and it is simpler to just click on a dock icon than activating QS, type a few characters and scroll down the list of object.  
(Version 1.0b35)

ANONYMOUS  I can't see what the big deal is about this thing. It's like a slow piggish version of Launchbar or Butler plus a few tons of useless lard and bloat.  
(Version 1.0b35)

ANONYMOUS  1.0b35 is also named 1C38. This makes using the MacUpdate Desktop app to keep track of newer versions quite impossible, as MacUpdate shows 1.0b35, but the application itself identifies as 1C38.

BIRCHMAN  This is an amazing product. it's a shame that when spotlight is released in tiger, the user base will dwindle. oh well...

anyways, this is the best launcher out there (launchbar can cram it). i think i speak for many people when i say this is the single best addition to OSX. i love this brilliant (free!) product.  
(Version 1.0b35)

RAWSWEETS  This is truly a awesome app.

I've used it to accidentally come across scores of files that I've long forgotten, by simply typing a few keys.

It's not the end all be all, because typing can take longer than clicking in a dock or dock-like app (I use dragthing), especially when what you're looking for is similarly named to other items - like "photoshop". In that case, you could type "pshop" and it will liekly list it first, but my point remains; two clicks or a hot-key can do it better.

And, although this app has hot-key support, so do many other apps and it's not unique in that regard. I personally like to bind launcher hot-keys within one app. Quicksilver is great for hot-keying actions, like "email file to tommy", etc.

All in all, I've had it for two weeks and don't use it so. I'm a web dev, and I'm either not doing much or am tired of figuring out which "index.html" file I'm working on - via QS's drop down lists.

What I look forward to with QS's development is the incorporation of Spotlight, or a faster cataloging method. I sometimes want to use QS to "action" files I've recently acquired, but these usually aren't cataloged immediately. I'd also like a module to handle selected items, like finder items or perhaps selected text - enabling QS as a kind of interactive services menu.

Well, it's a wonderful app with plenty good and more to come. Great work and highly recommended!
