App Fixer

App Fixer removes user preferences and saved application states for apps on your system, also resets Safari to aid recovery from adware hijacks and scams.

Does your favorite app keep crashing on launch, or quit unexpectedly during normal operation? Got an app that keeps starting up with unwanted settings or preferences that you can't seem to shake? App Fixer quickly gets apps like Photoshop, Safari or any other app that's misbehaving back up and running again when their preferences or window states have become corrupted or you just want to return to a defaults launch. App Fixer removes user preference plist files and saved application state files quickly and easily. No more hunting around in your User Library trying to figure out which ones to delete. Just choose the app and click 'Fix!'

• Improved: code-signing requirements are now checked on every launch to harden the app against the possibility of post-Gatekeeper hijacking.
