Getting startedDeploy Determinate with MDM

Deploy Determinate with MDM

💡

Most users should use the standard getting started guide.

  • Audience: IT administrators
  • Technical assumptions: JAMF, Mosyle, or a similar MDM provider for macOS

Create a “self-service” application which executes the script at the end of this article.

Security considerations

This script behaves similarly to Installomator, and validates the package before installing:

  • The package isn’t re-installed if there is no update.
  • The package is signed by our Apple Developer ID (X3JQ4VPJZ6).

A non-root user with administrative privileges needs to execute this script.

Handling updates

Re-run the installation script to update Determinate and Nix.

Uninstallation

To uninstall Determinate:

Uninstall Nix
sudo /nix/nix-installer uninstall
