I'm told that it does. You need to be using our latest Beta version and you must ctrl+click (or right click) the installer and click Open. Other than that once it's installed everything should be business as usual.
The HUD disappears quickly after a few hands. The HUD is still active, but it's not on top of the tables as it should be. I have the newest version of PT3 beta and I play on PokerStars.
Please enable logging (via Configure --> Options --> Logging Enabled), restart PT3 and reproduce this problem, then report it and we'll investigate further for you.
Hello! Same problem for me in France just after the OS X Moutain Lion installation !! I tried to install the 3.13.8 BETA but the problem is still there..
