That Steam stat is probably a chicken and the egg situation. I know I don’t run Steam on my Macbook because there’s nothing I want to play — but I would if there was.
Still the Mac marketshare is not that high (~15%?) but might start looking attractive to developers looking to “get in first” when hardware that can actually run games becomes available (cough).
I mean, it’s similar to Linux, right? Linux has about 2% on Steam, and that’s with compatibility layers like wine allowing many windows games to run cross platform. This [0] puts Mac at 9.5% of operating systems overall and Linux at 2.4%.
But games with native Linux support are not very common compared to Windows, even though it’s mainly a matter of supporting Vulkan, which many modern games already do. My point is that even though Linux should be relatively easy to support natively (compared to mac not supporting cross-platform graphics APIs out of the box), devs aren’t putting the effort in.
I really hope this changes, and hopefully mac “gaming-level” hardware could help push cross-platform work along.
