The guy doesn’t want Windows but is ok with Mac. That’s… not how it works. At all.
I think you’d find that many devs would opt for a Mac over Windows.
Hate both, but I’d run Windows over Mac any day (and I develop in both regularly since I have projects that require Windows and Mac, and will for a long time). But some of this is probably due to having to use the steaming pile of crap that is Xcode.
