My bad - I misread your post. Its the update to OS X that did it....yes, so far so good for me as well.

Excellent! Has the update been published on Steam? I haven't seen POE updated recently.

Aarik D - thanks for the post. Being the Mac tester, are you able to get the game to run in full-screen by doing a CMD+F toggle multiple times until it "sticks" on full screen (as i posted above)? And if so, what does that tell you about the source of the problem? Thanks!

Interesting. I did not run any sort of script, but just using Ctrl+F to switch back and forth the setting eventually "stuck" and I can play full screen (2560x1440) no problems. However, I have to do this each time I start the game. This seems to indicate that is it (possibly) not a driver problem (I have many other games that work fine fullscreen after El Capitan), and that a client update to correct this issue should be possible?
