Yeah but in game dev increasingly the tooling is integrated in the engine and so doing assets on a mac, then bringing them over to a PC and putting them into the game is an incredible unnecessary and annoying friction point.

Increasingly rare to find an artist that only works in photoshop and isn't working in the engine, directly putting their work into the game.

Accordingly even the art side is using PCs.

Yes but to try and experiment with those assets "in game", they'd need to use a PC.
