Nix not installing on macOS 15.0

[caldenmic]

Platform

• Linux:
• [ x] macOS
• WSL

Additional information

I was using this command to install nix:
curl -L https://nixos.org/nix/install | sh -s --

Output

Output

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.

It sounds like you've already got a Nix install (or at least remnants of one)--is there any particular reason you're trying to install it again?

I was using devbox but when i run the command "devbox shell" it doesn't run because it can't find /nix

This sounds like the issue/fix in this thread/comment:

• Rebooting always unmount Nix volume in macOS Monterey 12.5 #6839 (comment)

Can you see if that gets it working?

Same issue here after upgrading to macOS 15.0. The two launch items sh are enabled (they were never disabled AFAIK).
I'm not sure how to fix this, but can provide diagnostic data to someone who is.

I managed to reinstall nix again, with allowed my terminal to access full disk. https://nusendra.com/post/fix-nix-after-upgrade-to-sequoia

Thanks for the write-up! I'm sure my installation is fixed once i figure out how to force unmount the drive

What worked for me:

• unmount and delete the Nix Store in Disk Utility (thanks @nusendra)
• Delete nixbld group and users (with these commands)
• Maybe: enable full disk access to my terminal application (iTerm). Although I don't think this helped.

This got me back up and running. No other steps were need.

mine was just ran this command NIX_FIRST_BUILD_UID="3000" sh <(curl -L https://nixos.org/nix/install) (suggested by Nix error message).

Glad u got it working !
