Windows itself runs on ARM64 just fine. The third party software usually still requires Microsoft’s emulation layer. I’m not sure that Apple would still maintain Boot Camp, however. I doubt that that matters as much as it used to.
- cbhl 6y agoTo me, it's funny how the newer legacy software that's 64-bit only is going to be the problem in an ARM64 world -- the 32-bit x86 binaries will still be fine.
- Tagbert 6y agoThat might be a problem in the Windows world but it is unlikely to be a problem for Mac OS. This is likely why Apple finally shut down the 32-bit apps last year. Almost any app built using the Apple 64-bit libraries (both Objective-C and Swift) should be relatively easy to recompile with an ARM64 target.
- mappu 6y agoMy impression is that Microsoft are taking a very conservative interpretation of the x86 ISA patents (compared to e.g. qemu-user which has made this available for years now). Patents have a 20 year lifespan, most of the x86_32 ones have expired, but x86_64 is just barely still covered (the first publication was in 2000, and first commercial product was on AMD Opteron/Athlon64 in 2003). So it's probably just a matter of time before the userland emulation stuff is further extended, although we won't get anything newer than SSE2 for the same reason.
