Recently i've been having alot of issues with my 24" iMac. After reading countless discussions, none seem to have had the same answer as everything i have tried just doesn't seem to have worked?! Hoping you can give me a few more ideas and help narrow it down a little. (Fingers crossed solve it!)
The computer has mood swings - good days and bad days. On a good day it boots in a couple of minutes and on a bad day. I get the flashing folder unable to find a hard drive. Since my last clean install ... i haven't had that folder touch wood! But i do still however get the big bug.
After 10-15 minutes of using the iMac at normal speed whizzing around just doing general things on safari...thats it! its had enough.
Out comes the beach ball and the whole thing freezes apart from the cursor.
Launching a program will make it freeze, currently i launched the app store and its been frozen for a good 20 minutes with nothing.
Cant bring up force quit, either i wait sometimes 10 minutes sometimes an hour...or it has to be powered down by force.
Clean install, no additional software, 500gb harddrive, clean as a whistle!
Things i've tried:
Smart status, verify disk, repair disk, check disk etc..all the usual disk utility bits.
clean install of mountain lion.
-probably a few other bits i cannot think of.
-I cannot paste the actual details from about this mac as its..you guessed it! FROZEN!
From the serial number this is its spec: http://support.apple.com/kb/SP485?viewlocale=en_US&locale=en_US
Let me know any other details you might need. Hope i've posted correctly as this is my first time on the forum. Fingers crossed someone has an answer or had a similar issue and resolution. Thanks, have a great day!
