[QUOTE="RadDave, post: 1566389, member: 234411"] Hello All - I started this thread late last year concerning 'spontaneous' reboots of our new iMac - my MBPro purchased a month earlier has never had this behavior - both came w/ Mtn Lion which I upgraded to Mavericks - well, her iMac went for a month or more w/o a reboot, then has now done it twice the last few days. Tonight I ran an AHT (Apple Hardware Test, i.e. a reboot w/ the D key held down) - completed in about 4 minutes and NO problems were found - NOW, I don't know how reliable this test may be in detecting a CPU, Memory, etc. problem but just assume that it is fairly accurate. The messages seem to be the same as posted previously, i.e. the computer had to restart because of a 'problem' - never have gotten the multi-language dialog box, so not sure if these are indeed 'kernel panics' or something less minor? I've look @ multiple logs when these boxes pop up but have no idea what they mean. So, again just asking the best way to pursue this issue - any advice would be appreciated. Thanks - Dave [/QUOTE]
