Macbook Pro won't shut down I recently bought the 13"Macbook Pro retina (mid 2014). When I try to shut the laptop down, it doesn't work. I tried by manually closing all open applications but nothing happens when I press Apple Menu &gt; Shutdown. I also tried by pressing control+option+cmd+off but same results.
To find out which app is preventing the shutdown use

alt + cmd + esc

Try to force quit it from that screen.

If all fails hold the Power button for 10 seconds. 

That is the most crude way to shut down and as last option.
