Eject a CD/DVD from the Mac OS X menu bar
There are numerous ways to eject a DVD from a Mac, but using a relatively unknown menubar item you can do this directly from the menubar too.
To enable this feature, navigate to /System/Library/CoreServices/Menu Extras/ and double click on Eject.menu
The easiest way to do this is with the “Go To Folder” key combo, which is Command+Shift+G and then paste in
/System/Library/CoreServices/Menu Extras/ then locate Eject.menu to open it into your menu. Disabling the menubar extra is easy, just hold down Command and drag it out of your menubar.
