Blacklisted apps will be ignored, and the list will be automatically updated as new troublesome apps are discovered.

To avoid unnecessary headaches Xslimmer uses a downloadable blacklist, which tracks apps that do not allow themselves to be modified - to prevent piracy, usually.

Gain confidence by being warned in advance about side-effects, such as the need to reauthorize access to the Keychain.

Display extra info before slimming your apps, to learn all details about how Xslimmer will modify your application.

Know what you did, when and how much you saved for every application you slimmed down, and if something went wrong with one of those apps, you can restore the situation to its original state and report the app to us, so we can add it to the blacklist!.

Use the familiar drag & drop interface to add the apps you want to slim, or have the Genie find all the apps in your system for you - you may be surprised how many are installed! All found apps will be added as if you had dragged them in, so you can review them before slimming.
