This will happen in a few stages:

1. Make sure your computer doesn't already have Nix. If it does, I will show you instructions on how to clean up your old install.
2. Show you what I am going to install and where. Then I will ask if you are ready to continue.
3. Create the system users and groups that the Nix daemon uses to run builds.
4. Perform the basic installation of the Nix files daemon.
5. Configure your shell to import special Nix Profile files, so you can use Nix.
6. Start the Nix daemon. Would you like to see a more detailed list of what I will do? [y/n] y I will:
   • make sure your computer doesn't already have Nix files (if it does, I will tell you how to clean them up.)
   • create local users (see the list above for the users I'll make)
   • create a local group (nixbld)
   • install Nix in to /nix
   • create a configuration file in /etc/nix
   • set up the "default profile" by creating some Nix-related files in /var/root
   • back up /etc/bashrc to /etc/bashrc.backup-before-nix
   • update /etc/bashrc to include some Nix configuration
   • back up /etc/zshrc to /etc/zshrc.backup-before-nix
   • update /etc/zshrc to include some Nix configuration
   • create a Nix volume and a LaunchDaemon to mount it

Going forward, please try to either copy the output into the post, or attach an actual plain-text log file. Since PDFs are capable of containing exploits (and the fact that your comment says you attached an rtf, but the actual attachment claims to be a pdf), I had to go find a converter to ensure this was clean before I could take a look.

For reference, the error happens here:

I imagine you already have a user with the UID the installer is trying to use. There may be a better way to do this (I'm not terribly familiar with the macOS user-management commands), but I think you can run /usr/bin/dscl . search /Users UniqueID 301 to directly check.

Let me know what you find, but I imagine the most-likely cases and next steps are:

1. If you have already had Nix on the system before and the command matches a user that is named _nixbld1, we'll need to do a little more digging. (AFAIK the installer should handle existing nixbld users just fine, so we'll need to figure out why it isn't.)
2. If it is some other user, I think you'll have to find an open ID range. You can run something like /usr/bin/dscl . list /Users UniqueID | sort -n -k 2 and check it to see if you can find a sequence of available UIDs in the 200-400 range.
   • To actually use a different starting ID you'll need to either download+modify the install scripts to use it (I can outline the basics if you are you comfortable doing this?), or pre-create _nixbld* users (which the installer should hopefully pick up).

Hello NixOS/nix,

1) Following your instructions, I run :

% /usr/bin/dscl . search /Users UniqueID 301

which gives as result:

SonosDMS UniqueID = ( 301 )

2) Finding an open ID range , I did:

/usr/bin/dscl . list /Users UniqueID 301 | sort -n -k 2

Thanks. I think there are 2 main ways to proceed. I would pick whichever you feel most confident about...

1. I'm not sure what your SonosDMS user is for, but if you think you can change its UID without much hassle, I would try relocating it (perhaps to UID 300?). If you think this will be okay, I think it is fairly simple, something like: sudo dscl . change /Users/SonosDMSUniqueID 301 300
2. Download the installer script bundle, edit the script to change the minimum UID set in NIX_FIRST_BUILD_UID, and then run the installer locally. This will be a little do-it-yourself, but I do have a rough outline of the steps in https://github.com/NixOS/nix/issues/4915#issuecomment-862531976

You could also technically pre-create the build users if you aren't comfortable with the options above, but it will probably take more work all around.
