Mac is good computer. I have one I use only for patients. Security was a big point in buying it.
But Apple has not yet put out a dedicated gamer (or graphics ) machine that the PC market did.

I've had dell or Alienware. Alienware is putting out a nice 13" for $899. I have that because the
Large 18mx is not as portable.
I know Alienware is trying to focus on the entry gamer laptops for a reasonable price.

Be nice if Apple did too. And a price that is reasonable. Right now you have to be careful and make sure your computer
Will handle what you need. There are Apple forums. Just google that. Helpful people and they usually
help people to buy or upgrade when needed.
