Requirements

  • macOS 15 Sequoia or later.
  • An Apple Silicon or Intel Mac.
  • Free disk space for the app and the models you download.
Apple Silicon uses Metal GPU acceleration. Intel Macs use CPU inference. See Hardware for memory and performance guidance.

​
Install from the terminal

The installer selects Apple Silicon or Intel automatically, verifies the download, installs Magnitude in /Applications, and registers the magnitude CLI. Open a new terminal to use the command. Open Magnitude from Applications and follow Quick start. For a headless session, run magnitude serve instead; the installer does not require opening the desktop app.

​
Download the installer

  1. Visit Download Magnitude.
  2. Choose the download for your Mac. If you’re unsure, open Apple menu → About This Mac: a chip named Apple M1, M2, or another M-series chip is Apple Silicon; an Intel processor uses the Intel download.
  3. Open the .dmg and drag Magnitude into Applications.
  4. Open Magnitude from Applications, then follow Quick start. Opening the app registers the CLI; use a new terminal for the magnitude command.
To run Magnitude as a service on a Mac that serves other computers, see Remote server.

​
Updates and removal

Check Settings → Application updates to download and install updates. Restarting to update stops the running model and service. To remove the app, quit Magnitude and move it from Applications to Trash. Your downloaded models and settings live separately under ~/.magnitude; removing the app does not mean that data has been deleted. Keep that folder if you intend to reinstall.
