Hi there!

I'd like to play TR:A on MAC, but here's the thing I don't know if the game on MAC it's like a STEAM game that uses a key for activation of it or it's like a regular PC released of the game that you can install it without need a key.

So Can I buy a used copy of the game or I need to buy a new copy because of the key need it for activate the game.

Thank you!

I bought a mac recently and i think it has Mojave on it. I tried to install older versions of Mac software on it and forget about it.

I bought parallels for mac and installed linux and windows on it and installed all my favorite apps on it no problem. 

So if you get Parallels and install Windows even linux (mint in my case) and then steam you'll probably be better off.

I know they say Macs are so wonderful but I think they are only good for certain things.  Steam Links
