+1 for Keychron (also not affiliated), the C2 in my case since I don't need wireless. It's hard to find pre-built mechanical keyboards with Mac layouts. I previously had a WASD but made the mistake of going with clear switches that hurt my hand after extended typing sessions. That's not WASD's fault—it's otherwise a good keyboard—but there's no way to change the switches on that one. The Keychron can even be hot-swappable, and it was less than half the price of the WASD for comparable build quality.
