Tried it, the quality was terribly inconsistency and FaceTime’s use of phone number as AppleID and not needing username/password made it much easier to use.
I think Home app tops it. Just try if you have any HomeKit enabled lights for example. I think it's some half-assed attempt at just running the iOS version on the Mac. It's just so hilariously bad - I just now tried it again and I still have no idea how do the most basic of things - change the brightness of a light. There is a slider which on iOS you would intuitively know what to do with, but on this Mac version I have no idea what the input is meant to be.
i’ve never seen an app that can crash or lock the whole operating system
design-wise it looks completely out of place
