Quick Tip: Eject Media from Command Line on Mac OS X
Ever needed to eject a disc, cd, DVD, or media from the command line on a Mac? You can do that from the Terminal, as we’ll show here.
To eject a disc or media from the command line on Mac, open up your Terminal and type the following:
drutil tray open
or you can type to eject directly if you do not have a tray-operated superdrive or disc reader
Both of those commands should work to eject whatever media is stubbornly staying in the drive (unless of course the drive is damaged).
If you’re feeling cheeky and wanted to play a prank on someone, using those commands you could ssh into their machine and eject whatever media is in their drive, but that would be mean. On a more serious note, using the command line does offer remote ejection of media, which can be very helpful.
Perhaps you’ve run into the following problem: some inserted media (either a CD or DVD disc) refuses to eject itself when you hit the eject key. Often a reboot will fix this problem, but before you try rebooting, try the command line trick above, it just may work as well.
