>You’re seriously underestimating the support overhead of having a Mac app.

There doesn't have to be any "support overhead". You can simply offer the app as is, as tons of developers do. At worst, throw a "FAQ/common issues" page and leave it at that.

I have tons of apps, and very successful ones (judging from their publicity/store placement), that offer absolutely no support.

>Let’s say there’s 200k UIKit developers in the world. That’s still clearly less than 10% of professional and hobbyist software developers.

It's still clearly way more than needed to have a huge market. Heck, 5% of pro and hobbyists developers would still be enormously huge.
