Stupidly Bad OS Problem With MBP

Question

I know, it was an incredibly stupid thing to do but I moved a file called 'SKPlugins' out of the core services folder and put it in the trash!! now the dock doesn't load, the side bar doesn't load and worst of all.. drop and drag doesn't load so I can't drag the folder out of the trash and back the the core services!! can anyone suggest anything that could work? is there a way to hook my mbp to a pc as a hard drive and drag it back from there??
Cheers,
James

Answer 1

Try this:
Boot the computer and after the chime press and hold down the COMMAND-S keys until the computer starts up to a black screen with white print. When the startup completes you will see a command line prompt with a white block cursor. Enter the following command lines pressing return after each:
/sbin/mount -uw /
cd /Users/yourusername
ls -l .Trash
Verify that the folder (SKPlugins is a folder not a file) is still in the Trash. It should be listed after the last command issued above. If so continue as follows:
mv .Trash/SKPlugins /System/Library/CoreServices
ls -l /System/Library/S*
The last command should verify that the folder has been moved from the Trash back to it's proper location.
At the prompt enter 'reboot' without quotes to restart the computer. I would repair permissions immediately.
