Recovering from a failed installation on macOS

Run the uninstaller

If /nix/nix-installer exists, run the built-in uninstaller:

sudo /nix/nix-installer uninstall

Typically, the Determinate Nix Installer (opens in a new tab)'s uninstall phase is thorough and complete. In rare cases, further steps may be necessary.

Delete the "Nix Store" volume

Typically, the Determinate Nix Installer's uninstall phase is thorough and complete. In rare cases, further steps may be necessary.

If the Nix Store volume exists, delete it.

1. Open "Disk Utility"
2. Right click "Nix Store"
3. Click "Delete APFS Volume..."

If the volume does not exist, move on to the next step.

Delete secrets from Keychain

1. Open "Keychain Access"
2. Search for "Determinate"
3. Delete the entry for "Determinate Nix Store encryption key" if it exists
4. Delete the entry for "Determinate Nix" if it exists

If neither of these entries are in Keychain, move on to the next step.

Complete

Determinate should now be uninstalled. Try running the installer again:

curl --proto '=https' --tlsv1.2 -sSf -L \
  https://install.determinate.systems/nix | sh -s -- install --determinate
