With some more path checking we could make this accessible to both Linux and Mac devs.

Then I'll have to look into potential deployment options.

@rods-honorio Off the top of my head, if we just check for the existence of macOS specific paths before trying to back them up, this should be pretty easily doable. But I'm probably overlooking something, so a thorough code review is going to be needed for this issue. I'll spin up a VM to test this on once we're feeling good about it.
