The reason why MacOS grew in popularity is because it started to be used by pros, myself included, i.e., I've switched from Linux to MacOS seeing many top computer scientists using MacOS. However, after over 10 years of using MacOS, I'm actually still not sure whether it was worth it, and I'm considering to go back to Linux since a few years. The main reasons stopping me from switching is a reliable Calendar app and concerns about battery life.
