Recently upgarded to mountain lion from snow lepard and having issues with 2008 macbook 5,1 waking from hibernation. the system freezes when attemping to wake from sleep - The system is not stock. I upgraded the HD to SSD and ram to 8GB... the system was fully functional on snow leopard and had no issues with hibernation.
I have tried the following with no luck...
clean installed OS X
adjsuted power saving settings - disabling the hard drive sleep option
updated hibernatemode to 0, 3, and 25
created new profile
Has anyone else run into this issue ? - this is very furstrating and I do not want to downgrade to snow leopard.
MacBook (13-inch Aluminum Late 2008), OS X Mountain Lion
