From the seymour:cards blog:
if anyone was considering a mac but was worried about their poker suffering, I wouldn't: poker lives, and it lives on the mac!The blog post has something to say about Poker Copilot:
Although it is fairly basic vs Poker Tracker 3 or Hold'em Manager, it does go someway to filling the void. I've only been using it for 24 hours but I had zero problems setting it up, it hasn't missed any hands, hasn't frozen or had any other compatibility tantrums. Something that neither Poker Tracker or Hold'em Manager can claim, at least in my experience.
That's exactly what I aim for with Poker Copilot. Software that simply works.
