After reading the other posts here are my thoughts. I generally shut down my machines at night. Like Tee it is a force of habit from way back, another reason is that with my G3 on OS X it doesn't go to sleep properly so I don't get the power saving benefits of a sleeping computer. I also have my Energy Saver panel preferences set to screen saver after 15 minutes, hard drive sleep whenever possible and auto-shut off at 12:30 each evening (morning?), usually auto on at 8 AM during the week, which I change depending whether I'm going to be home or not. This way I don't have to remember whether I've shut the computer off or not. Talking about sleep - this is the same as turning your computer off with respect to daily, weekly and monthly maintenance scripts that OS X runs at pre-scheduled times. You would still need to use something like MacJanitor to ensure this gets done. You could also try a program called OnyX which can do many additional maintenance things that Mac Janitor doesn't. It comes in a 10.4.x version and a 10.3.x version; pick your flavour. It is freeware and avaialble at the following link: http://www.titanium.free.fr Martin On Apr 10,2007, at 9:47 PM, Gerhard Kuhn wrote: > Shutting down the Mac each night is actually not recommended as some > maintenance utilities run during the night.
