DESCRIPTION
Xslimmer removes wasted space on your Mac's hard drive by removing the binary from either its PowerPC or Intel code (depending on the system architecture used). The result users report is that you can save 47% of your disk space.
For example, when running Xslimmer on Google Earth 4, it shrinks the size from 101MB to 52.8MB, which is a 47% reduction.
As the developer states, the driving goal of Xslimmer is to achieve size reduction without compromising functionality. As of version 1.2, the option to strip applications from unwanted language files and localizations is added. Version 1.2.7 improves Leopard support by automatically excluding Time Machine paths from the analysis process.
Additional features for safe use include a "blacklist" and a custom folder list (which is by default populated with key system locations). This prevents problems with applications (or the system itself) that will no longer work after size reduction.
With the "App Finder Genie", a user can list all size reducible applications on the hard disk and choose to slim them and save a considerable amount of hard disk space.
WHAT'S NEW
Version 1.6.3:
- File ownership/mode not accurately preserved in rare occasions. Xslimmer 1.5.3 would sometimes not correctly preserve all metadata information of slimmed files. This was an infrequent problem; in addition, most times it had no impact on the slimmed app. A few apps, however, were reported for blacklist inclusion due to this bug, when in fact they should not need to be blacklisted. Thanks a lot to Thomas Clement, the author of TimeMachineEditor, for alerting us about this issue!
- Potential crash fixed. A rare crasher that could happen on a disk error condition has been prevented.
REQUIREMENTS
Mac OS X 10.3.9 or later.

GARY30 I have used this application for over two years and never had a problem. Nevertheless, it would be foolhardy to use a produce like this without taking some elementary precautions. Xslimmer gives the option to back up the files it slims and produces a log. So if i ever have a problem I am confident I could restore the files with no problem. I also have Time machine and Super Duper. One thing that surprises me with 1.6.3 is that the Adobe CS4 applications are NOT blacklisted. Adobe has always been a problem and its bloatware is something i would definitely like to slim. For now, I have subtracted them from the Xslimmer list on my own machine. If anyone has had success slimming CS4 applications that information would be most welcome.

RICOBLUES Great software. I run it on all application of my MacBookPro. No problems and fast loading of apps. I'm very satisfied. Have a nice day, Riccardo.

CASTLE I ran Xslimmer on all the apps in my app folder that weren't blacklisted. I'd say about half now won't launch and are having to be re-downloaded. Examples include LiquidCD, MacPAR Deluxe and Wallet.

CASTLE That's one hell of a coincidence, then. All of these stopped working IMMEDIATELY following my use of Xslimmer, and have worked perfectly since I reinstalled them (and haven't used Xslimmer since doing so).

SIMONM Some of the gains are amazing, especially on the Apple apps. Mail from 289 to 40 Mb, iChat, 115 to 17.4, iCal, 94 to 16 etc etc! The interface could use a little improvement, like being able to sort the list of apps prior to slimming based on potential saving and being able to export slimming log, but the guts of the program run fine! Saved over 4 Gb on my nearly full laptop drive.

GARY30 I have been using this program for almost two years and had only one problem. I just replaced the slimmed file with a backup which was generated by the program. As with any software that utility that you know is going to poke through your files, you will want to make sure you have a current backup before running. You can use a program such as "Easyfind" to see if (or where) there are leftover "lproj" resources. You can also use a number of programs that are indiscriminate to varying degrees to remove all such files from all packages (except a language you want to keep). I think Xslimmer is a reasonably safe and convenient option.

DANA SUTTON I wouldn't touch a program like this. Mucking around with programs' code sounds like a great way of inviting trouble. And what's the benefit of shrinking programs' sizes in a day and age when disk space is so cheap and plentiful?

PMASON Now Xslimmer has really done it. On a 2.4 Ghz Intel Core 2 Duo machine, the application wrongly figured it was running on a Power PC processor and proceeded to merrily remove the wrong code from hundreds of applications. I sent the developer a screenshot showing the "About this Macintosh" Finder window and the About window from Xslimmer, side by side. The Finder reports "2.4 Ghz Intel Core 2 Duo", Xslimmer says "Running on PPC". These crippled applications will have to be reinstalled. These results are forcing me to conclude that Xslimmer is dangerous. Earlier this month the developer offered my money back. I said never mind. But as I wrote to him a few minutes ago, now I'm taking their offer. Santiago, Chile

PMASON Further to yesterday's comment, a check of applications that had unwanted language packs removed by Xslimmer shows that, in fact, these were removed from the first level only. While a Get Info on the application will show that only the desired language(s) remain(s), in fact hundreds of unwanted language packs still reside inside these applications, only at deeper levels. These will not show in a Get Info window. As such, you will not notice unless you check the application package contents, either manually or with a file finder utility. It therefore appears that Xslimmer doesn't work recursively, which means that the point of removing unnecessary material is being achieved only partially.

PMASON Trouble in paradise. Running a fresh Leopard install on a PPC machine, Xslimmer 1.5.3 has just stripped Spanish language packages from some applications, although Spanish is selected as one of my two language preferences (after English) in the International panel of System Preferences. Most strange of all, I'm now finding that random components in the (expressly excluded) System and Library folders have also been stripped of Spanish language packages. I have two internal discs with identical Leopard installations, so comparison is easy and definitive. The more I compare, the more components with missing Spanish language packages I'm finding. Where this has happened, the component has been left with only an English language package, whereas the identical component on the other internal disc has both English and Spanish language packages. I normally run in English, so this is not an immediate disaster. But it does mean that my computer can no longer startup in Spanish. Given the circumstances, I won't even try. Getting my machine back to pre-Xslimmer state will require a complete reinstallation. I'm not amused.
