I have a late 2012 model iMac with OS X Mavericks installed. When I go to wake the iMac after a long period of inactivity (2 days for example) it behaves in one of two ways:
- Sometimes the iMac wakes immediately, meaning the desktop shows up right away and all applications are snappy and ready to go.
- Other times after waking, the desktop view is grayed out with a status bar at the bottom of the screen which takes a couple seconds to complete before un-graying the desktop. After the desktop is un-grayed, applications and other user-interactions are slow to respond, as if the computer is still "warming-up".
My Energy Saver preferences are set to put the display to sleep after 5 minutes of inactivity, then the computer to sleep after 10 minutes of inactivity.
Why this inconsistency in waking?
