I've been looking for an "out of the box" MacOS-friendly mechanical keyboard for a while now. So far, the recent Keychron keyboards seems to be the only real contender, and unfortunately from all reports they are just to tall and cause wrist pain.

This seems like it would be a great alternative where you could have a Mac configuration - with media keys - mapped pretty easily with a custom keycap set (unless I'm misunderstanding?).
