[QUOTE="chscag, post: 1597892, member: 46727"] Any activity that would prevent sleep. It could be some background process or just about anything. What don't you try something else for us? Restart your iMac in safe boot mode. (hold down the shift key and restart) Safe boot mode stops all third party drivers, startup programs, and verifies the hard drive. It also kills the sound - you can ignore that. Run that way for awhile and see if it will sleep. Let us know. [/QUOTE]
