I want to know if anyone else is experiencing this. Two days ago, i updated an Adobe app on my machine (I believe it was Acrobat, but not sure). Later that day, I noticed that a page seemed to have had frozen. I rebooted my system and it froze at the boot screen. The only way I can access my machine is to boot in safe mode, and then I have no sound, and other features. Has anyone experienced this as well? Also, how do you uninstall an updated app on the IMAC?I have Mac OS X v 10.6.7 and the IMAC with 2 gb memory and 1.83 GHz Intel Core Duo. I know, I know, time to upgrade.....but until then??? Thanks!
