PokerTracker

Hello,
I want to get a HUD working for play money tables in a pokerstars home game. I read that PT3 supports that.

I have the trial version of PT3 on my Mac running. Unfortunately, it doesn't read the play money HHs.

Is that because of Mac or the trial version or am I maybe doing something wrong?

Where did you download the PokerStars client from? You need the .COM client - the .NET client that only supports play money also doesn't write hand histories. The .COM version however will do so.
