I have an iMac 2.16GHz Intel Core 2 Duo running 10.4.11 and would love to use it to boot my MacBook 2GHz Intel Core Duo running 10.5.4 so I could use the iMac as if it were my own computer (for the bigger screen).
Is this possible via Target Disk Mode?

iMac 2.16GHz Intel Core 2 Duo, Mac OS X (10.4.11)

    If you want to put your MacBook (with Leopard) into FireWire Target Disk Mode and use it's hard drive to boot the iMac, that should be doable. I have a small external FireWire drive with Leopard that I use as an Emergency/Maintenance Startup Disk for a few Macs, PowerPC and Intel. What you propose would not be any different.

    If the MacBook is a newer model that came with Leopard, I would not try it the other way, using the iMac (with Tiger) as the target for the MacBook to boot from, because the MacBook may only support booting Leopard (or later).

    There's also this clever program that uses VNC to let you turn the iMac's screen into a second screen for your MacBook. Or the other way around...


    I use it along with an old laptop running Ubuntu Linux, to give my iMac a THIRD screen.

    I tried ScreenRecycler but the screen resolution prevented me buying the app.
    I'll give the Target Disk Mode a try tomorrow and see how it goes.

    Thanks for the help.

    The resolution can be whatever you want it to be (just change it in System Preferences Displays pane). The refresh rate is a bit slow because it's going over the network. It work much better if you use an Ethernet cable at gigabit speed, versus Airport.

    I have my third (ScreenRecycler) screen showing mostly static windows, such as my email list in Mail.app and Address Book.
