    Hi guys,

    I own a 2006 24" iMac, and a (slightly) newer Macbook Pro (2008).

    Can I use the iMac's monitor with a third party software like this or like Synergy?

    My biggest issue is I need Mountain Lion to install a program, but I need the big screen to use it properly.

    Please don't tell me "just buy a new iMac". Thanks

    No target display mode did not come into play until 2009 see apples notes here.

    Your best bet might be to sell the iMac and use the money to buy monitor for your macbook.
