Nix installation fails on macOS (High) Sierra

[ebzzry]

This is the output from

curl -o install-nix https://nixos.org/nix/install
sh install-nix

downloading Nix 1.11.15 binary tarball for x86_64-darwin from 'https://nixos.org/releases/nix/nix-1.11.15/nix-1.11.15-x86_64-darwin.tar.bz2' to '/var/folders/9s/l0ks1r093p786j3nkp5dzv080000gp/T/nix-binary-tarball-unpack.XXXXXXXXXX.7N45JFOM'...
Switching to the Multi-User Darwin Installer
Welcome to the Multi-User Nix Installation

This installation tool will set up your computer with the Nix package
manager. 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 one.

2. Show you what we are going to install and where. Then we 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 we will do?
[y/n]

We 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 we'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/profile to /etc/profile.backup-before-nix
 - update /etc/profile to include some Nix configuration
 - 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
 - load and start a LaunchDaemon (at /Library/LaunchDaemons/org.nixos.nix-daemon.plist) for nix-daemon

---- let's talk about sudo -----------------------------------------------------
This script is going to call sudo a lot. Every time we do, it'll
output exactly what it'll do, and why.

Just like this:

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo echo

to demonstrate how our sudo prompts look


This might look scary, but everything can be undone by running just a
few commands. We used to ask you to confirm each time sudo ran, but it
was too many times. Instead, I'll just ask you this one time:

Can we use sudo?
[y/n]
Yay! Thanks! Let's get going!

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo test -e /var/root/.nix-defexpr

making sure that /var/root/.nix-defexpr doesn't exist

    $ sudo test -e /var/root/.nix-channels

making sure that /var/root/.nix-channels doesn't exist

    $ sudo test -e /var/root/.nix-profile

Something went wrong, and I didn't find Nix installed at

We'd love to help if you need it.

If you can, open an issue at https://github.com/nixos/nix/issues

---- oh no! --------------------------------------------------------------------
Jeeze, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.

I've been trying to reproduce this, but I'm not having any luck. What version, exactly, of HS do you have? Hopefully with the next patch of HS plus #1700 will fix this.

[giorgiga]

I have the same issue on macOS 10.13.2 (17C205) (ie: the latest version) and nix 1.11.16

[giorgiga]

I have been able to determine that the issue is caused by me having umask 0027 in my .bashrc (or, rather, by the install script not working with such umasks).

See PR for a fix.

@vcunat seems like this could probably be closed since the reporter made a PR to fix? NixOS/nixpkgs#39115 might fit better here than at nixpkgs, but it's specifically caused by administrative software such as JAMF

[vcunat]

The PR claiming to fix this (#1825) is merged and released, so I'll assume this is fixed.
