Issue description

It seems the test suite fails on x86 darwin, which is an issue for distribution in nixpkgs.

Expected behavior

success

I don't have a mac myself, so i cannot help test this, CC @happysalada

The error makes sense but we also test on all platforms so I would expect us to catch it before nix pkgs. Going to have a look.

[ruben-arts]

Already found it. We're testing on macOS-latest which was changed to also be a ARM machine....

[ruben-arts]

That said, it won't fix these specific issues. As you're apparently running on a macos 10 as build machine. :fearful:

[ruben-arts]

Question for the team, are we going to support MacOS 10.16 as a supported platform to run the tests on?

This would require to test on it and add the system-requirements to the test manifests where that is important.

[baszalmstra]

I dont think we should add CI resources to test specifically for 10.16. But I did fix this issue in #1855
