- Open Terminal. You will need to convert the file to XML (from binary) so you can edit it in TextEdit. The command you need is
plutil -convert xml1 ~/Library/Preferences/com.apple.spotlight.plist
- Edit this file in a text editor. Just before at the bottom, add the following:
<dict>
<key>enabled</key>
<false/>
<key>name</key>
<string>SOURCE</string>
</dict>
- Convert the file back to binary using
plutil -convert binary1 ~/Library/Preferences/com.apple.spotlight.plist
- Log out and back in again.
