Or if he installs Boot Camp on the Mac, he can just use that (though I'd think that a 2011 MacBook Pro might be a bit underpowered for a newly released game like Civ 6). That way he can have computers with two different operating systems in the house, and play on whichever one he wants. I'd say if the OP wants to cover his bases, then buying through Steam is the way to go. As it is, I have access to both versions of both games because they came through Steam. Since some of the best mods for Civ 5 are Windows only, I tend to play Civ 5 on Windows using Boot Camp, But I play Europa Universalis using the Mac version. In fact, I'd say that buying games on the Mac App Store is generally a bad idea precisely because you do not then have access to the Windows version, which you do get on Steam. You could purchase the Mac version of Civ 5 through Steam and happily play that version and take no notice of whether or not a version was available on the Mac App Store.
