No shut down

Not clear on what you mean by "shut down".

Do you mean that your computer won't sleep? You can't shut down the computer with the Power button?

Please clarify...
No when I am done with my MACPRO and go up to the APPLE MENU>SHUTDOWN it will not shut down
 
My guess is there is an app that pops up a dialog "Save work before exiting?..." but is hidden/blocked somehow. Do you also have problems logging out?
 
I've had this as well...

The only thing that worked for me was to
1. Force a shutdown of the computer. pull the plug if you have to.
2. Reset SMC before rebooting
3. Then Do MULTIPLE resets of PRAM, one after another...3 times in a row works for me.
4. Then once you are back up and running, repair disk permissions.

Then try shutting down the computer. It should, hopefully, work then.
 
Yes happens to my macbook air when I plug in my external monitor as well... everytime I shut down I have to disconnect my monitor. Very annoying. Wish apple would fix this asap

What is SMC?
 
Do you use Virtualbox?

I don't know if the issue is still present but as recently as 4.3.2 (last time I verified), VirtualBox would refuse to totally shut down VMs under certain circumstances, even though VirtualBox itself would quit.

This caused Mavericks to be unable to shut down without being forced.
