There's a huge class of application and professional tools that will not survive a hypothetical transition from x86 to ARM. That is indisputably correct, and the people in this thread who are worried about having to switch platforms in order to keep using the tools and applications they are using in macOS today have legitimate concerns.
Gaming is not one of those things. The only reason you can't run iRacing on ARM is because iRacing is a boutique game written by a small software shop that doesn't even support macOS on x86 any more. They used to, but they dropped support because the market was too small to justify the expense. However -- that's not a fundamental architectural limitation of ARM. It's just a marketplace reality. ARM -- the architecture -- is just as capable of supporting graphics and CPU performance to compete with x86.
@Bruno Castelló is completely off in the weeds when he says that ARM is incapable of the performance needed to run his favorite games. It can't because those games don't exist for ARM. They could. But they don't. They probably never will, either, so he's got an echo of factual basis in his protest, but he is correct for very wrong reasons. iRacing will never run on macOS ARM because iRacing doesn't even run on current macOS X86.
In a world where macOS is on ARM there's no
technical barrier that prevent high-end games being ported to the platform. It's tough to imagine the market leading to that future though especially since the market has already shown us that there's no money to be made porting games to macOS on x86 either.
So that brings us back to people who are worried because Boot Camp, VMware, Parallels, Docker, and other virtualization tools are impossible to port to ARM. That's totally true. And if
@Bruno Castelló is using Boot Camp to run Windows games on his current Mac, then he's in that boat too. Unless the good folks at iRacing port their game to macOS
again. Seems unlikely.
