You'll have to follow the uninstall instructions before reinstalling it: https://nixos.org/manual/nix/stable/installation/uninstall.html#macos
For future reference: since you were reinstalling because Nix was missing from your PATH after a macOS update, you don't have to reinstall to fix this. The macOS update is overwriting the shell hook, but you can just replace it. See #3616 for more.
Platform
macOS M3 Pro
Additional information
I have installed Nix before, to install PianoTrans (https://github.com/azuwis/pianotrans) and it worked successfully. However today, I could not launch pianotrans, and whenever I tried to run a Nix command, the terminal did not seem to recognise the command. So I tried to reinstall Nix. It gave me this error and did not show me how to access "/etc/bashrc" or "/etc/bashrc.backup-before-nix" which is why I am now creating this post on the issue. It is likely the "backup before nix" file/folder would have contained my old installation of Nix should the installation have continued which isn't supposed to happen. If anyone knows how to help, that would be greatly appreciated!

```log ---- oh no! -------------------------------------------------------------------- I back up shell profile/rc scripts before I add Nix to them. I need to back up /etc/bashrc to /etc/bashrc.backup-before-nix, but the latter already exists. Here's how to clean up the old backup file: 1. Back up (copy) /etc/bashrc and /etc/bashrc.backup-before-nix to another location, just in case. 2. Ensure /etc/bashrc.backup-before-nix does not have anything Nix-related in it. If it does, something is probably quite wrong. Please open an issue or get in touch immediately. 3. Once you confirm /etc/bashrc is backed up and /etc/bashrc.backup-before-nix doesn't mention Nix, run: mv /etc/bashrc.backup-before-nix /etc/bashrc We'd love to help if you need it.
