The Chooser does not appear in the Apple (

) menu.

If the Chooser isn’t listed in the Apple menu, the System file on your startup
disk may be outdated, or you may have removed the Chooser from the Apple
Menu Items folder in the System Folder on your startup disk. You can obtain
the current system software from an Apple-authorized dealer.

Make sure that you have only one System Folder on your startup disk.
