If you are seeing the grey progress bar after the machine has been idle for a while, you may want to take a look at this article:
Mac computers: Progress bar appears after waking from sleep
http://support.apple.com/kb/HT1757
With the release of the OS X Mountain Lion v10.8.2 supplemental update 2.0, a new feature was introduced to enter safe sleep after four hours of the computer being connected to AC power. This is an effort to comply with the European Energy Standards (ErP Lot6). This will only occur if there is no wireless or Ethernet activity and no activity from external devices such as USB storage devices.
This is normal behavior for the following units:
- MacBook Pro (13-inch, Mid 2012)
- MacBook Pro (15-inch, Mid 2012)
- MacBook Pro (Retina, Mid 2012 and later)
- MacBook Pro (13-inch, Retina, Late 2012 and later)
- MacBook Air (13-inch, Mid 2012)
- MacBook Air (11-inch, Mid 2012)
- iMac (21.5-inch, Late 2012)
- iMac (27-inch, Late 2012)
- Mac mini (Late 2012)
Cheers,
