Hi @ljrk0 ! I'm only seeing your issue now, the darwin-aarch64 package should be available now. We're building it using Github Apple M1 runner since #741

Can you confirm it works ?

Thank you for coming back to me! I missed though that the core issue is not the CI but the build flake for Nix not claiming macOS on ARM support. Had some time to investigate and add the small fix :)
