a) To temporarily allow packages that are unsupported for this system, you can use an environment variable
   for a single invocation of the nix tools.

     $ export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1

b) For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnsupportedSystem = true; }
in configuration.nix to override this.

c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowUnsupportedSystem = true; }
to ~/.config/nixpkgs/config.nix.

All set!

I'm on macOS Monterey 12.0 Beta (21A5543b)

also having a similar issue after upgrade to monterey and new mbp

also having a similar issue after upgrade to monterey and new mbp

In my case, the setting for terminal opening with rosetta2 didn't carry over when i transferred everything to the new mbp. Enabling terminal to open with rosetta2 and reinstalling solved the issue for me

Yeah we don't support m1 natively atm, you need to run dapptools under rosetta until we upgrade to a new version of ghc.

+1 on this, any eta on a possible upgrade to a new version of ghc?

I'm considering to buy a new Apple Silicon MBP, but since I use it to write Solidity, compatibility with dapptool is of importance to me. Can you maybe comment on the difficulty/complexity of supporting a ghc version compatible with e.g. the M1 chip? Thanks

Bump for sadness

Did the { allowUnsupportedSystem = true; } part. Still: error: cannot bootstrap GHC on this platform

Also getting the same issue here:

error: Package ‘ghc-8.10.4’ in /nix/store/wgjf744s860krnci5g5qwlcdsrf1d7iy-nixpkgs-release-21.05/pkgs/development/compilers/ghc/8.10.4.nix:254 is not supported on ‘aarch64-darwin’, refusing to evaluate.

is there a workaround?
