Trimmit!0.95b

Be aware that apps like Trimmit can break code signed applications such as Mail.app on 10.5 if the strip debug symbols option is enabled. This is why it is a good thing to have the backup option enabled. I can manage to consistently break Mail.app and cause it to popup the password window. It will then never remember the password, attempt to store or attempt to retrieve it from the keychain *if the Application code signature is invalid*. In testing I've tried removing many things from Mail.app such as language files, compressing images, removing redundant unnecessary files and stripping the redundant PowerPC binary and various other things from the bundle. None of this seems to damage Mail.app's code signature. How do you break Mail.app you ask? By stripping the debug symbols from Mail.app using one of many app trimming applications such as Trimmit. Since Mac OS X 10.5 Leopard introduced Code Signing and Apple Mail is code signed my guess is that because the bundle is changed and the code signature is then broken and invalid Apple Mail is then treated as an untrusted application and is refused access to the keychain by SecurityServer. According to http://developer.apple.com/releasenotes/Security/RN-CodeSigning/index.html applications should trigger a popup confirmation to allow the Application to update the keychain but it appears that Mail.app does not do this and SecurityServer suppresses the dialog as the code signature is invalid.

Excellent application for removing excess files and recovering valuable HD space. Works very well with all the applications. I used it to trim Google Earth from 94.7 MB to 49.5 MB. Cyberduck was trimmed from 22MB to 6.6MB. Some people have suggested that their apps seem to open faster, and I agree with it. I would like the ability to trim multiple apps at the same time. Right now it only allows one application at a time.
