Hi Vilap23!
I play on a macbook pro as well. I must say playing on a mac can be hard from time to time.
Like you said Pokerstars do have the software as does PartyPoker. And it looks like a lot of rooms are creating mac software. I'm not sure which once have it already and which once don't
And I see you have poker tracker, thats good since HEM doesn't have mac software yet. A lot of rooms provide an instant play option. Which is playing in your internet screen. But for a true grinder that is crap 
I installed parallels on my macbook with xp on it. I only use it to play poker though. If you're not sure how it works and you want to see it add me in community and I'll gladly give you a demo.
If you have any questions just shoot!
