You can be difficult to develop for if you're in a good position. Sony had to do a lot of work cutting the price, creating exclusives, etc. to get units sold to make the PS3 an actually desirable place for developers to target. Early on there was plenty of "PS3 has no games" memes. Apple hasn't done the work to make the Mac an attractive platform for game developers. It's extra work for a pittance of extra sales.In the end all of this doesn’t really matter. Most of the arguments people have about Mac do not make sense.
“It’s too difficult to develop”
PS3 was very difficult and it did just fine
“macOS is hostile by dropping support for old technologies”
This 32 bit drop again. People do realize this was done to get ready for Apple Silicon Macs right? They gave developers enough notice. It’s not Apple’s fault if developers abandoned their products. And by the way, Windows 11 can’t play every game realized even in the Windows XP days either.
“Linux is overtaken macOS in popularity”
Well valve has an actual product that uses Linux so of course they well prioritize that. Linux gaming sucks if you use an NVIDIA graphics card. Which is what 90% of these gamers on these threads want Apple to use again. Regardless the stats do not reflect this. Even the slight increase is due to the Steam Deck. If Valve actually spent even a minor effort in macOS and made the Steam client nice, people would use it more. I ultimately just re-purchased Factorio on their website and bought some games on the App Store because I just can’t deal with Steam’s issues. I’m tired of it locking up and force closing it every day.
It's not just the 32 bit drop. Apple dropped Classic support with Leopard/Intel, so 1984-2000ish era games became unplayable, they dropped PPC support cutting off early OS X titles, then the 32 bit drop. And I wouldn't be surprised if they drop the depreciated OpenGL support in the near future or Intel support. They have a reputation for doing it repeatedly. Sure, not every Windows XP game works on Windows 11 but it's a great many more than early Mac OS X games (Only one I can think of off the top of my head is Sim City 4, no idea if a PPC Mac CD version of that will even update to be usable on ARM either).
Linux gaming with Nvidia is really not that bad. AMD is better, but I'd wager it's better than macOS.
