Does anyone know the difference between sleep vs. doze under OS X (10.3.9 specifically)? Now that I am fully backed up, I have once again set my iMac to allow sleep and am still having problems, but only when it is allowed to sleep for a large chunk of time. I'm trying to get more info so I can try to pinpoint the problem. Trouble always occurs when I wake it after it has "slept" overnight, even when booted from the TechTools CD instead of the hard drive. I have been unable to replicate it during the day, and I'm wondering how long the machine must be in "doze" mode before it goes to "sleep". Thanks! Samantha
