Can I use my Macbook Pro Retina as extra monitor for my iMac through Thunderbolt I just bought a new late 2013 iMac and a new late 2013 Macbook Pro retina. Also bought an Apple thunderbolt cable.

Pressing CMD+F2 (enabling Apples "Target Display Mode") on my iMac lets me use the iMac as external monitor for the MB Pro, but I'd like it the other way around (which doesn't seem to work).

Does anyone know how I through Thunderbolt (for speed, am aware that apps like Air Display and Screen Recycler can do it through WiFi) so that my MB Pro becomes an extra external monitor for my iMac?

While this question addresses this problem for earlier hardware and software, I'm looking for a solution that supports using a thunderbolt cable and works with late 2013 Macs with OS X Mavericks.
If you really don't want to do it over the network, the retina MBP's display uses DisplayPort internally. You could disassemble your machine and use this pinout to connect it via Thunderbolt.
