By default, once you enter x86_64 Rosetta 2, macOS will try to run everything in x86_64. So an x86_64 Nix will still try to use x86_64 even when system = aarch64-darwin. To avoid this we can set kern.curproc_arch_affinity sysctl. With kern.curproc_arch_affinity=0, we ignore this preference. This is based on how https://opensource.apple.com/source/system_cmds/system_cmds-880.40.5/arch.tproj/arch.c.auto.html works. Completely undocumented, but seems to work! Note, you can verify this works with this impure Nix expression: ``` { a = derivation { name = "a"; system = "aarch64-darwin"; builder = "/bin/sh"; args = [ "-e" (builtins.toFile "builder" '' [ "$(/usr/bin/arch)" = arm64 ] [ "$(/usr/bin/arch -arch x86_64 /bin/sh -c /usr/bin/arch)" = i386 ] [ "$(/usr/bin/arch -arch arm64 /bin/sh -c /usr/bin/arch)" = arm64 ] /usr/bin/touch $out '') ]; }; b = derivation { name = "b"; system = "x86_64-darwin"; builder = "/bin/sh"; args = [ "-e" (builtins.toFile "builder" '' [ "$(/usr/bin/arch)" = i386 ] [ "$(/usr/bin/arch -arch x86_64 /bin/sh -c /usr/bin/arch)" = i386 ] [ "$(/usr/bin/arch -arch arm64 /bin/sh -c /usr/bin/arch)" = arm64 ] /usr/bin/touch $out '') ]; }; } ``` |
