curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install linux --no-confirm --determinate
. /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh

works for us on Semaphore CI

Oh, sorry that's for Linux, not Mac.

@fzakaria are these ephemeral installations of macOS, or long running? Either way: is this step part of an orchestration tool or something?

[fzakaria]

Just CI like a GitHub Acrtion

It's already trying root so not sure why still Operation Not Permitted.
