Can anyone help me with a problem I've just encountered with a 2009 MBP, I've just installed a new 500gb hard drive in the MBP and then cloned a clean install of os x 10.7 on to the new drive.

I then updated the 10.7 to 10.7.5, and have just realised that when I shut the MBP down the machine just restarts.

Any solutions anyone?

Based off the replies in the comments, this is what I suggest doing:

In terminal, type the following command:

cd /Library/Preferences/SystemConfiguration/

sudo rm

sudo rm

(Do the "rm" commands separately). Note: might not exist. Then, shut down your mac, if it re-starts, just shut it down again and hopefully everything will be ok.

I hope this works.
