Add Eject Menu to Mac Menu Bar
To add an eject menu to the Mac OSX menu bar go to HD/System/Library/CoreServices/Menu Extras/Eject.menu, double click that and you can eject your cd tray from the menu bar. Wonderful! (especially for those of us that don't have an eject button on the keyboard)
Also, to remove the menu once it's installed hold down the option key and drag the menu off the menu bar.
