Mac Mini will not shut down

[Bacong]

My Late '09 Mac Mini absolutely will not shut down normally through the command. (specs in sig) I went through the command yesterday, took a nap and when I came back to the computer nearly 5 hours later it still hadn't I've fixed permissions. Is there anything I can do?

I don't even know the keyboard command to shut down - I always use the Apple menu.

Use a precision adjustment tool?

I meant that I shut down via the menu.

When you tell it to shut down, do you get the Shut Down dialog box?

Do you let it complete the automatic shut down countdown or do you click the Shut Down button?

When you come back is the Desktop still on the screen?

Have you tried quitting any/all software that you have running before issuing the Shut Down command?

 

[Bacong]

Yes, of course I select the shut down dialog. Everything is normal until it gets to the blue screen right before it would normally shut down, except nothing happens from there.

Give this a try:

Intel-based Macs: Resetting the System Management Controller (SMC)

Boot with OS X install disk
Open Disk Utilities
Repair disk

I'll try both of those suggestions should either fail, thanks.

My drobo control panel stops my mini shutting down. I have to force quit the control panel before my mini will even think about closin down.
