    I'm trying to track down issues I'm having with target disk over thunderbolt. Basically you should be able to attach two thunderbolt machines together and make one the external display of the other by hitting cmd + f2. This isn't working on my MBPr for some weird reason. Anyone have any ideas. It's not because it's running on battery power.

    Only iMacs can be put into Target Display Mode.

    But You can enter in Target Disk Mode (press T before boot) on the one MacBook and boot up another MacBook from the first one (press opt before boot).

    Ok, that's what I needed to know. Thanx a ton for the reply. Just trying to get to the bottom of Apple's ridiculous thunderbolt target display mode implementation. I can't seem to get my external displays waking on sleep over thunderbolt. Never had a problem in the pre-thunderbolt days.
