Greetings, I have a dual 2.0 G5 with 2gb of ram. I would appreciate anyones help. Ever since upgrading to 10.4.8 a few weeks ago I have the following two problems: I can't put my computer to sleep The fan revs really high periodically (at least once, twice per week). Then I have to force restart. I haven't changed anything since installing Tiger. I did repair my disk permissions. Waiting for the upgrade to Disk Warrior.. glad they make upgrading customers wait 4 plus weeks.. Thanks in advance.
