Getting started the second time: *where* is `nixbld`?

Help
1

Running on macos after an attempt to install this perhaps half a year ago.

Despite following the instructions to uninstall nix, I’m faced with this during installation:

---- oh no! --------------------------------------------------------------------
It seems the build group nixbld already exists, but
with the UID 30000. This script can't really handle
that right now, so I'm going to give up.

You can export NIX_BUILD_GROUP_ID=30000 and re-run.

We'd love to help if you need it.

Question: where on nix / macos are the _nixbld users and group registered? Is it possible to clean them up? I’d like to avoid a snowflake setup if at all possible.

Ah-ha. Looks like the cleanup instructions need to be taught about this. Something like:

for i in {1..32}; do sudo dscl . delete /Users/_nixbld$i; done
sudo dscl . delete /Groups/nixbld

then try again
