IMac fails repeatedly - Hardware, Firmware, os Software?
I have been having problems with this computer - long boot time, poor response, no boot. At a suggestion I removed Norton, booted from the backup partishion. Repaired the disk and reloaded Mountain Lion. It worked for a few hours and then the disk corruped again. Not sure what is wrong. I am running now from clone on a portable disk.
iMac, OS X Mountain Lion (10.8.2), Early 2008
