Noticed today the display on my MBP won't sleep; this is what I've done/tried thus far: - Gone though my programs and none of them seem to be the culprit. - Quitting every app and leaving the computer idle with nothing running, display still doesn't sleep. - Double checked system preferences and made sure nothings conflicting. - Also of note, the screen saver will trigger and work fine. - Permissions repair did nothing Any idea's?
