As a fellow Mac user, I think you’re in for a challenge finding Mac media keys from anyone but Keychron, at least from my observations. Unfortunately most keycap sets don’t even include Command or Option keys. I own one Akko ASA profile set which does include those. I’ve also seen that PBTFans sets generally include Cmd/Opt, but I don’t personally own one. Best of luck!
Yep, for the price Lack can’t be beat. I’ve read that some clever people even use them as server racks since the legs are just the right width.
