I’ve had the opposite experience; I’ve literally never seen anyone using Safari on a Mac. Even tech illiterate people always seem to end up with Chrome somehow.
Lol, no. An important reason for me to not use Safari is that it doesn't support uBlock Origin, 'tech illiterate people' rarely care about ad-blocking.
I used Firefox before safari because of uBlock Origin, but performance and battery life were big problems. There are ad blockers in Safari gives me the same end result as uBlock Origin.
Anecdotally, GSuite works a lot better on Chrome than any other browsers I've tried. Unsurprisingly companies opting for GSuite will see a larger share of chrome use, it might as well be preinstalled when handing down the computer or mandated at IT level when the intranet and other corporate SaaS is explicitely tested for chrome first.
