Thats dumb IMO to discriminate against OS. Very large number of startups do use Mac, do you offer same mentality to them?
We are a business, not a charity daycare, we do have to actually *judge* employees we hire on their merits.

Modern day macOS is "fine" for the people who will be doing everything they do in Google Chrome.
The organizations I tend to frequent are of very high talent density, hence a software developer who forthcomingly prefers macOS and is clueless about *software* (ie operating systems) in a fundamental way is looked down on (and rightly so) by the higher echelon of talent.
