Dyslex1k
Current if you want to develop Worlds/ Avatars on an Apple Silicon Mac you need to use Rosetta for components of the SDK to still function. This is going to be impossible after in 2028 when Rosetta is removed from Macs. This means it would be ideal if there could be patches made that made the SDK Instruction agonistic.
Currently There is only 1 major area that does not support it in the current SDK version (3.10.4):
  • Harmony errors for memory access:
Exception: mprotect returned EACCES

I understand that Mac may not be a supported platform but it would be really nice for VRChat to implement packages and tools that do also work on Arm processors. Not only could this benefit Mac but also windows and Linux Arm based systems.
