Mac OS X 10.4: "The ‘%@‘ preferences pane could not be removed" alert

If you've installed third-party applications that install their own preference panes in System Preferences, you can easily remove the third-party panes. However, sometimes the instructions may not work for you. For example, you may get the following alert when you try to remove a pane:

If so, use these steps instead:

1. Close System Preferences if it's open.
2. In the Finder, choose Go to Folder from the Go menu.
3. In the resulting dialog, type /Library/PreferencePanes/
4. Click Go (or press Return) to open the PreferencePanes folder.
5. Locate your third-party preference pane files (they end with ".prefPane"), and move the ones you don't want out of the folder or put them in the Trash (enter an administrator's password if prompted).

Note: If you want to reinstall the third-party preference pane, use the third-party software's installer. Make sure you're using a current and compatible version of the software.
