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.
Version 1.5.3 eliminates the need to restart your system after having slimmed signed applications that access the Keychain, thus avoiding the problem of certain apps apparently forgetting their keychain-stored passwords until the next reboot, if they had been used prior to slimming. It also includes a fix for a potential crash that could happen when installing a license containing a malformed date format.
Core slim improvements
- Signed apps no longer seem to forget their keychain-stored passwords. When slimming signed applications that store passwords in the Keychain, they sometimes seemed to forget them until the next reboot. This was caused by the system caches becoming confused after the application files had been modified, and thus only happened if the applications had been used before slimming them. The slim process has been reworked to avoid this effect, so the user should no longer need to reboot after slimming signed apps.
- Improved fidelity to original app file attributes. The slim process will try to replicate whenever possible the original file attributes, such as modification time stamps, of slimmed files.
Bug fixes
- Potential crasher fixed. Previous versions of Xslimmer could potentially crash when trying to register a license containing a malformed date format. Such a license has never been issued, so no users have been affected by this bug.
Mac OS X 10.3.9 or later.
