Oops. I accidentally broke the Mavericks support while making it Yosemite compatible. This version works on both Mavericks and Yosemite.

However, the old version is included in Psychtoolbox, so you'll need to remove the old version from Psychtoolbox in order to get MATLAB to use the new version.

Resent, as the forum software is acting up again :(  
  
Ok, the new one is merged for a future beta. But if i remember correctly, i tested the old one on OSX 10.10.2 or 10.10.3 on my 2010 MacBookPro single display, and it worked - i don't have any 10.9 anymore so it must have been 10.10. If it needs now special cases on your machine to work on 10.10 then that hints to some potential funny new compatibility problems even on the same OSX version.
