Developer website: If Then Software
Killustrator addresses a few outstanding bugs in Adobe Illustrator 10 (for OS X only) including the dreaded crash during the loading of fonts at program startup. The program also can remove the main Illustrator preferences & Adobe online preferences, which are also known problematic Illustrator files. The software can run automatically on launch, and most choices are preferences that can be saved. The program can even quit itself & launch Adobe Illustrator when it has completed running. Even if you don't have the aforementioned problems yet, Killustrator is a great program to keep by your side when you do get the Illustrator strangeness.
Mac OS X 10.2 or later, Adobe Illustrator 10.0 or later
