Thunderbolt

[harlex]

I have a 17 inch Macbook Pro i7 Late 2012 and a i7 imac late 2011 and have connected them by thunderbolt cable, I have tried to make my iMac into a target display but it will not work. I have pressed cmd +F2 on either the mcp or the iMac.
I know the MBP works with an external display as I have connect it to a pc monitor using mini display port. I haven't tried the iMac yet but maybe I am doing something wrong.
Anybody had this problem if so what is the cure.

Found this via Google:

Success!!! I finally got Target Display mode working. Here's how it's done:

Connect a Mini DisplayPort cable to the ports on each computer.
Boot primary computer (MBA).
Boot target computer (iMac).
Press ⌘-F2 on the keyboard of the external display computer.

The boot order is important - boot the target computer first and Target Mode won't work. This isn't apparent from the documentation.

Audio pass-through worked great too. Yay for Thunderbolt!

Try that maybe? I think the key is to press ⌘-F2 at boot-up, which it does not sound like you were trying to do. Not sure.

Considering that this is only February of 2012, I have no idea how you managed to get ahold of a Late 2012 anything.
