Is it harder to play PA on a Mac?

Hello,
I can't find any thread about PA on a Mac (the search here doesn't find anything with "Mac" or "OSX" or "OS X"? Weird), so I open a new thread.

Is PA playable on a Mac? I'm having quite an hard time to replicate what I see on YouTube, and my screen is different, plus the way keys are bond doesn't really work for me, it slows me down a ton. And apparently I can't re-bind.

The Zoom also is weird. It is moving way too slow (I'm using the mousewheel), and all suddenly it goes in orbit. Also, I can't see the paths of units, and the paths of the building queue.

This way to properly play I need three hands, a pause option and no AI/adversary on the map. Actually, there is a sandbox where one can practice the most efficient path of building/improvement?

Well, are you having a different, more enjoyable experience? And if so, how can I fix mine?

Thanks in advance. Otherwise the game is awesome.
