I have a MacBook Pro Mid 2012 running latest release OS X. Recently when I am shutting down my computer it just get stuck in the spinner. So the only way is to force shut it down which might not be good for the computer. Do I have to reinstall the firmware or I can do something to help it? Thanks

Note that this doesn't happen when trying to shutdown in recovery mode.

  • @Tetsujin I booted into safe mode and it fixed that problem once, but when I start normal boot, the spinner come again. – Tom Shen Jun 20 '16 at 12:32
  • only 6 other steps to try then ;) though, seriously, you ought to do the safe boot again when you reach that step. – Tetsujin Jun 20 '16 at 12:34
  • @Tetsujin The rest doesn't seems to help, just the safe boot fixed it once. – Tom Shen Jun 20 '16 at 12:58
  • @TomShen is there a message about an app running when you try to shut down? Have you installed any apps recently (right around the time the problem starting occurring)? – owlswipe Jun 21 '16 at 0:09
