I never understood this, because surely some huge percentage of developers use Macs. Enterprises buy stacks of them nonstop. Just making that group happy would get you the reputation of being a developers machine, for serious computer people, which could translate into laymen purchases too.
Would developers really be happy with containers running macOS inside? Production is running Linux, so they need two sets of images and their local image will be different from the one running in production.
I'm really not sure what comment you're replying to but Mac developers write code that runs on linux primarily using Docker and "VMs" that run linux on docker. Like; probably 75% of the devs on the west coast do this.
