How do you manage to run Mountain Lion on a PM G5? I'm guessing you are running a Mac Pro generation 3 or higher.
You might instead try to determine why your computer will not wake from sleep properly.
Try creating a new user account with admin status. Log out of your account and log into the new account. Does the problem persist. If not, then you have something in your user account that is causing the wake from sleep problem. Now comes the hard part - finding the cause.
Hi, Thanks for your response.
I have a
Intel Power Mac
2.66 GHz Quad-Core Intel Xeon
not a G5.
I have been trying to find out a solution to how to fix my not waking from sleep problem, but I cannot find the answer. It seems like a lot of other people are having the same issue as me. It only started to happen after I upgraded to Mountain Lion last week.
I usually did put my Mac to sleep before this started to happen.
Now I'm wondering if I should just leave it on or turn it off when I'm not going to use it for a few hours.
Thanks in advance.
Well, try my suggestion from my previous post. Unless you have a hardware problem this is a fixable problem. I've been using a Mac Pro since 2006 and have not had such a problem. Often they trace down to a corrupted file that is preventing some process from waking up or sleeping properly.
You can leave it on all the time if you prefer, but it would be better to fix the problem.
If Kappy's suggestion doesn't isolate the problem, you might try booting into the Safe Mode as it resets some things.
The following has worked for some Macbooks, and the same might apply.
Boot to Recovery drive (command - R). Run Disk Utility/Repair Permissions and Repair Disk. Reboot to startup disk. Hold down the option key while using the Finder "Go To Folder" command. Enter ~`/Library. Delete Cache folder and Cookies folder. Empty trash.
