    Is there a way I can use my old iMac as an extra display for my new iMac?
    My new iMac uses thunderbolt so I'm curious how I could set this up.
    Here are the specs for my old iMac

    20-inch, Late 2006
    Model Identifier: iMac5,1
    2.16GHz Intel Core 2 Duo
    ATI Radeon X1600 128MB

    and my new iMac..

    27-inch, Mid 2011
    Processor: 3.4 GHz Intel Core i7
    Memory: 12 GB 1333 MHz DDR3
    Graphics: AMD Radeon HD 6970M 2048 MB

    Any help will be greatly appreciated!

    I think the answer is no - it seems target display mode didn't get added until 2009 models.

    Your newer 27" has the capability, but only for other thunderbolt macs. The previous 27"'s could take a mini-display port input.

    I was thinking that maybe if you faked out a second display on the newer machine, you can back-to-my-mac on the old machine to this fake display. But even if that did work, it would probably be pretty clunky - slower updates, having to deal with waken up both machines together, etc.
