I am following that. And the errors above are not now appearing.  The nix-build of server and client worked ok after rerunning a few times. However the step of running nix-shell is now giving an error.

The previous errors with file descriptors I suspect are from corrupt download of cache or corrupt cache.

No it does not affect at all because GHC comes with Nix. When you enter a in a shell you already have access to all plutus dependencies.

I am seeing an error building Plutus-Apps on Mac M1.
After precisely following
https://github.com/renzwo/cardano-plutus-apps-install-m1/blob/main/README.md
UPDATE: This did resolve. These errors appears to be due to corrupted cache in nix store from download on in the cache itself.

> **username_0**: I am following that. And the errors above are not now appearing.  The nix-build of server and client worked ok after rerunning a few times. However the step of running nix-shell is now giving an error.
