I have a 2012 MacBook pro that I use as a school laptop. It has pretty decent hardware, and I wanted to play D3 so...

I can't stand Windows either.
And Galaxy instead of iPhone because Android

.
More issues with the Mac side of things:
Auction House causes client to crash.
Starting a game from the game options instead of saving and then starting a game from the main menu crashes the client.
Being in a party and having someone start a game in the manner mentioned above crashes the client.
Starting a game in an act you weren't in prior to that crashes the client.
Defeating Magdha on Master difficulty in HC causes your character to die...

.. actually user error there.
Also, the graphics aren't quite right. There are a lot of excess flickering and distortions.
