I'm posting here because I can't pin this issue to a particular version of OS X.
My Early 2009 White MacBook/2.0GHz Core 2 Duo/4Gb RAM/OS X 10.6.7 (Build 10J869) will
sleep if I invoke the Apple Menu or function-control-eject > S, but will not
sleep based on my SysPrefs > Energy Saver settings.
- trashed HD/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
- logged in to my test user account
- zapped PRAM
- safe booted
- booted into my Leopard 10.5.6 volume
all with no joy.
The only on-the-markGoogle hit
I found did not reach a solution.
Can anybody offer any insights or suggestions. (I'm not
looking for a 3rd party solution such as is mentioned in the linked doc.
PS: I had turned "Safe Sleep" off and cleared its file in /var/vm, but clearing the above plist reset the pref and restored the file; my sleep issue manifested itself under both sets of circumstances.
