| \* macOS 15 Sequoia introduces a change where system upgrade may overwrite the `_nixbld1–4` build users, which breaks Nix sandboxing. A [repair script](https://github.com/DeterminateSystems/nix-installer/releases/tag/v0.26.0) is available via the Determinate Nix Installer and upstream channels. |
There was a problem hiding this comment.
Linking to the determinate installer isn't right here. There's already a migration script in-tree: https://github.com/NixOS/nix/blob/master/scripts/sequoia-nixbld-user-migration.sh.

Updated information relating to compatibility of Nix in different OS, especially macOS.
Motivation
The current documentation on supported macOS versions is outdated. It does not reflect the current minimum system requirements (macOS ≥ 11.3), compatibility with macOS 15 Sequoia, or upcoming support changes planned for future Nixpkgs releases (25.11+). This PR updates the manual to reflect accurate architecture and OS version support as of Nixpkgs 25.05.
Context
This PR improves clarity for users installing or upgrading Nix on macOS. It also ensures developers are aware of changes in OS-level compatibility and platform deprecation. The changes are sourced from:
This change is documentation-only and non-invasive.
