Late 2013 MacBook Pro Retina + 2 Thunderbolt displays + Apple Cinema Display @2560x1440? I saw this answer by griewei here:
https://apple.stackexchange.com/a/124479/81640

Unfortunately I don't have enough rep to comment.

What I would like to do is something similar e.g.
 - one latest greatest Mac Book Pro Retina
 - 2x Thunderbolt Displays
 - 1 Apple Cinema Display via HDMI adapter etc.

@griewei said he was doing this and it was working; does anyone know if the Apple Cinema display is scaled at 2560 x 1440 in this configuration?

I know it was not possible in Mountain Lion but I heard it was possible in Mavericks

Thanks!
This is my current setup with a late 2013 MacBook Pro
