Anyone else experiencing this problem? Everything was fine before today. I downloaded and installed all the OS X and iOS updates today (a whole crap load of them! ) and now Aperture crashes every time I launch it. Sometimes it says the database is corrupted and wants to rebuild it, which it does, and then it again crashes. Other times it just crashes immediately. Hmm.... this is bad. Of course, I filed a bug report and uploaded all of the crash reports. Meanwhile, does anyone know how to revert an update?
