Help ! System preferences disappeared on me !

Question

I just recently started using the iMac so while i was "experimenting" I accidentally dragged the System Preferences icon from the dock and it disappeared with a dust cloud After that i tried to restore it by dragging system preferences from the menu bar to the dock. This didn't work though. Then when I tried to open System Preferences from the menu bar again nothing happened. Can anybody explain to me what i did wrong and how to restore this without having to reinstall everything ???

Answer 1

The "real" System Preferences application is located in your Applications folder. Simply drag the System Preferences icon in the Applications folder to the Dock. That will restore it in the Dock.
Normally System Preferences is not in the Finder's toolbar unless you put it there.
Now, if you cannot find System Preferences in the Applications folder then that means you probably have deleted it. If you have not emptied the Trash then open the Trash (click once on its icon) window and drag System Preferences out of the Trash and back to the Applications folder. If you have emptied the Trash then your life has gotten a bit more complicated, and you will need to extract a new copy from your OS X Installer Disc. To do that see the following:
How to Use Pacifist to Replace Deleted OS X Applications
Insert the OS X Installer DVD into the optical drive. Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items. Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
defaults write com.apple.finder AppleShowAllFiles Yes
Press RETURN.
To turn off the display of invisible files repeat the above command substituting No for Yes.
The install packages are located in the /System/Installation/ folder on the DVD.
Download the shareware utility Pacifist from VersionTracker or MacUpdate. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
