A week ago I upgraded my 2.16 GHz Intel Core 2 Duo 20" iMac with 2 GB of
RAM from 10.4.11 to 10.5.2, and the automatic Sleep was working just fine
(according to my Energy Saver settings). Then I applied the Apple
Security
Update 2008-002, and now it won't automatically sleep! I tried futzing
with
the Sleep settings, but it didn't help. I have it set to put the computer
to sleep when it is inactive for 20 minutes, sleep the display after 10
minutes, with Wake for Ethernet network administrator access UNCHECKED.
How
do I fix this?
