I’m not sure if you can run Alby Hub itself  on macOS. Umbrel and Start9 can be installed on a mini PC and they have Alby installers. I access my Alby Hub on Umbrel with my MacBook. Go to nostr:npub1rxysxnjkhrmqd3ey73dp9n5y5yvyzcs64acc9g0k2epcpwwyya4spvhnp8 profile and find the video on Alby, it’s good.
