+### xv6 stuck on qemu-system-i386 macOS Apple Silicon
+
+If your shell is stuck on  `qemu-system-i386 -nographic -drive ...` after running `make qemu-nox` or returns an error `rosetta error: Unimplemented syscall number 282`, you may need to disable Rosetta emulation in Docker.
+
+Uncheck the "Use Rosetta for x86/amd64 emulation on Apple Silicon" option in Docker Settings > General. (thank you to @WardahJabeen for this suggestion in [#13](https://github.com/camerondurham/cs350-docker/issues/13#issuecomment-1904634853)!).

 ### xv6 stuck on qemu-system-i386 Windows
 
 If your shell is stuck at `qemu-system-i386 -nographic -drive file=fs.img,index=1,media=disk,format=raw -drive file=xv6.img,index=0,media=disk,format=raw -smp 2 -m 512` after running `make qemu-nox`, it probably means you don't have WSL/WSL2 enabled properly.
