Apple and games....
The iPhone is so popular that gaming devs have taken to it. And Apple has noticed that, seeing some easy money coming in, and now Apple are investing and advertising the gaming capabilities of the iPhone.
The Mac?
M1 / M2 Max / Ultra have very decent hardware capabilities for gaming.
Apple is not doing nothing to make games on Mac work well, but they're not exactly helping enthusiastically either:
Years and years of lagging implementations of OpenGL and below-par 3D grfx hardware in Macs (only the later Intel Macs and Apple Silicon have decent hardware), the removal of 32 bit support, introducing Metal (although good API, still, it is "the alternative" to the much wider used Vulkan, which makes game devs think twice about supporting it), and of course the pretty low marketshare of the Mac in general. Add to that, only the higher-end Macs are (were..) capable of running games decently really.
Another thing: Apple's supposedly native support for the G29 racing which was announced druing WWDC 2022 for macOS Ventura. It never came... Now with RC of Sonoma available, the whole native wheel item is "just disappeared", I am sure game devs love that sort of dedication...
It has always been love - hate with Apple and games on Mac... (mentioned this below somewhere before here..)
• Intro iMac in 1998: Unreal is available (!), but completely unplayable on an iMac. Even the G3 Power Mac had no decent 3D card to play it on mediocre settings...
• Quake 3 Arena demo during Mac OS X demos: crashed during the live demo on stage (Apple must have hared that..)
• Doom 3: showing off GeForce 3 on Power Mac G4....but, it took years and years after launching Doom 3 for PC that the Mac port became available
• More of this.. demos on stage, announcements made.... but stuff actual released: too little too late.
BUT....For me, I love to play games on my Mac Studio M1 Max. I do not want to buy an additional PC, just for gaming.
So, for me it will do with the games I enjoy: X-Plane 12, GRID and DiRT games.
