Mac Pro won't go to sleep automatically

[davidmac27]

I have set the Energy Saver option to 10 minutes for both display and computer. However, after 10 minutes of inactivity, only the display goes to sleep. How do I fix this?

I have this same exact problem. My Mac Pro always went to sleep fine, and i changed the setting once so it wouldnt sleep at all, and now after i change it back to about 10min, it never wants to sleep...regardless of what i change it to. Anyone know how to fix this?

Dave, I have researched this through several forums and in Apple Support and you are the first to describe exactly the actions that have caused my MBP to not automatically go to sleep. Interestingly, I have moved the settings and it will sometimes go to sleep on its own Have you had any luck with the issue? The Apple Support forums are saying it could be Parallels, the PMC? may need resetting, etc, but I have not found a definitive answer. - Matt

Never had a problem with mine.

The problem seems to be isolated to the Macbooks and MacBook Pro's.

Yet two people are posting that they are having problems with the Mac Pro.

Update to 10.4.10 and make you have the latest firmware updates.

Mine has/had this problem too. When I uninstalled the Last.FM client it slept like it should -- when I reinstalled I had to force sleep it.
