Hello. Today I ran a routine Software Update, installing most of the recommended available updates namely updates for iPhoto (2009), my Canon printer, and a Java update. After they finished installing, Firefox promptly stopped working and now suffers from chronic beachball syndrome upon starting. I've tried all the possible troubleshooting methods within the application, so I'm starting to become pretty sure that the culprit is the Java update. Apple.com had a page on how to deactivate installed updates, but that appears to only apply to OS X <= 10.5, and since I'm running 10.7, that's no good (I tried, of course). Does anyone around here know how I would go about deactivating and/or rolling back an already installed update? Thanks in advance.
