My Mac Pro is in an endless loop at startup, have the Apple on the screen but won't go any further. I need to install the start-up disk but can't get the DVD player open. Keyboard is not available. I know it's something simple but can't find anything in the reference material.

Mac Pro, Mac OS X (10.7.5)

    Five ways to eject a stuck CD or DVD from the optical drive


    Ejecting the stuck disc can usually be done in one of the following ways:


      1. Restart the computer and after the chime press and hold down the

          left mouse button until the disc ejects.


      2. Press the Eject button on your keyboard.


      3. Click on the Eject button in the menubar.


      4. Press COMMAND-E.


      5. If none of the above work try this: Open the Terminal application in

          your Utilities folder. At the prompt enter or paste the following:


            /usr/bin/drutil eject


    If this fails then try this:


    Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

    Thank you so much for your reply but my problem seems to need a way to manually open the DVD drive so that I can insert the start up disk before turning on the computer. On some drives they have a pin hole you can insert a paper clip and release the locking mechanism and this is what I am looking for.


    I do appreciate your response

      Follow the instructions above.  Insert the disc.  Shut down the Pro and restart with the disc in the drive.


      There is a pin hole in the front of the drive, but not usually accessible with the drive in place.  You can remove the side cover, slide out the optical drive bay out to access the pin hole that way.

    Hold down the Alt/Option key as you Restart. This invokes the Startup manager, whose code is all in ROM.


    Over several minutes, it will draw an icon for each potentially-bootable Volume. When has found all available, the watch-cursor disappears and the Eject key on the keyboard goes "live". It can be used to open the drawer, then insert the Disc, push it shut and the Mac will scan for the new Volume and draw an icon for it if it appears potentially-bootable.


    Alternatively, the silver door in front of the drive can be pushed down and the paper clip hole can be accessed through that door, provided you have a bright light at hand to find the hole against the jet black face of the drive itself.
