After about an hour I managed to install PT3 on my macbook (with OSX Lion)
When I run PT3 and use the auto import, and start playing, no HUD shows up, I also notice that it does not seem to be importing hands, and when I tried to import one manually, it said unrecognisable file.
It's all running in English, and it matched up with the auto detect fine.

I'm using the trial version if that makes a difference
