Flyover country checking in. Non- or semi-technical bigcos of the sort with big IT departments who take most of a week to get you your laptop when you start, are almost all Windows but may tolerate some macOS. Technical bigcos are mixed Win/macOS, with the business side preferring Windows and the tech people all on Macs. Smaller tech companies are all Mac, pretty much universally. Every now and then you get the one weirdo whose laptop can never connect to the projector and whose screen sharing always fucks up on calls or takes 5 minutes to get their bluetooth headset working, because they're on Linux (disclaimer: many years ago, I've been that weirdo). I've only seen one shop that was mostly Linux + Windows with little or no Mac presence, and they were in hardware (drivers or proprietary libs for embedded devices can be hard to come by Macs).

I can firmly say this does not match the United States at all.

Occasionally you have a need for an iOS dev, but outside of that Mac's are not used professionally.
