Just today, my iMac has started a nasty little habit. It has frequently stopped responding. It has happened 4 times today, in the span of about 6 hours. The latest time it happened was during the software update to OSX 10.5.8 Anyone have any general solutions to help repair this problem. The only thing I have really tried is repairing the disk permissions. I've searched a little for a similar posting or forum for this problem but haven't found anything quite useful. If there is a published article or forum posting somewhere i overlooked, i apologize for the thread, and if someone can link the information, I would be greatly appreciative.
