Pros:
Very sophisticated design.
Very efficient and well optimized operating system.
Manufacturing quality.
You need specific software or that works better in the Apple System.
Cons:
More limited software available than in Microsoft and Linux.
Price, it is very expensive.
Very closed environment, you tie to Apple for almost everything.
Very expensive technical service and some parts may not be standard.
Forget playing most games, because it does not support them as it should.
Not all the game, but some games like Diablo 3, Dota 2, HoTs, Overwatch, WoW are well supported. 😬
