Okay well elaborate of what you will use it for.

If you are going to be modding with programs such as Modio, Horizon, Profile Editor, or any other modding tool then DO NOT buy a Mac

If you are going to be using Photoshop or any other Adobe software, editing software, anything involving the arts (music, graphic design, etc..) then I recommend that you DO buy a Mac because they are very good for these things.

I am in an Academy course at my high school and we use Mac's everyday as we learn all of the common art programs (illustrator, photoshop, cinema 4d, after effects, etc..)
