I think it’s safe to say that Steam stats undercount the potential size of the Mac gaming market. There are a few reasons for this:

- The trailing effect of Apple’s underpowered Intel Macs. For many years the average Mac was an Intel MacBook Air, which never had a hope of running many contemporary games.

- As a result, few developers tried to target Macs, which meant Steam felt like a bit of a ghost town for Mac users.

- Store fragmentation with the App Store and Apple Arcade.

I think given the switch to Apple Silicon, and the fact that Apple platform users are typically willing to pay money for things, that the potential revenue share from Mac users could be a lot higher than 2.45% of the PC gaming market if the games were there.

EDIT: I do think that unless Apple does something more to jump start gaming on their platforms that it will never reach its potential. I think they should acquire some studios and pay for exclusives like their competitors do.
