That won't make a difference -Mac OS X does not work in the same way as Windows.
1. Open a Finder window.
2. Click on your Home folder (with the house icon).
3. Click on the Library folder then the Preferences sub folder.
4. Move the file "com.apple.iTunes.plist" to the trash.
5. iTunes will now start with default settings and the plist file will be recreated.
