When i click on shutdown nothing happens. I've tried repairing and verifying the hard-disks. Rebooting in safe mode, resetting PRAM, SMC. Nothing seems to work.

The only 2 ways i can shutdown now is by pressing and holding the power button and typing "shutdown -h now" in terminal. Can anyone help me?

It would be useful if you'd include the kernel log, especially the shutdown related parts. – Max Ried Dec 14 '11 at 13:27
I think I've experienced the same thing. A background process gets stuck and prevents the shutdown. For me, it doesn't do this if I log out and then shutdown from the login window. – ughoavgfhw Dec 14 '11 at 15:45
If you open Activity Monitor, are there any processes that are red (not responding)? Be sure to look at All Processes (dropdown at the top right). – Mr. Jefferson Dec 14 '11 at 15:55
