TyrnBeta

macOS

Tyrn runs on macOS on Apple silicon or Intel. For Linux, see Linux.

Install

Tyrn is in private beta: request access with GitHub at tyrn.dev and we email you the download link. Open it, accept the license agreement and drag Tyrn to Applications. The app is notarized, so Gatekeeper opens it without extra steps.

Install the CLI

Choose Install CLI from the Tyrn app menu. It links /usr/local/bin/tyrn to the app’s command line tool. If your account can’t write there, macOS asks for an administrator password. See Command line.

Can’t install CLI

If you cancel the administrator prompt, nothing happens. If the install fails, for example because your account isn’t an administrator, Tyrn shows “Couldn’t install the Tyrn CLI” with a Show me how link to this page.

Create the link yourself from a terminal with an administrator account:

Terminal window
sudo mkdir -p /usr/local/bin
sudo ln -sf "/Applications/Tyrn.app/Contents/MacOS/cli" /usr/local/bin/tyrn

If you don’t have administrator rights, link it into a folder you own and add that folder to your PATH:

Terminal window
mkdir -p ~/bin
ln -sf "/Applications/Tyrn.app/Contents/MacOS/cli" ~/bin/tyrn

Permissions

Tyrn may ask for access to files and folders, or an administrator password for Install CLI. Programs that run inside Tyrn, such as a harness or a terminal command, can trigger macOS prompts for things like the camera, microphone, contacts or location. Those prompts name Tyrn. Allow only what the task needs. You can change them in System Settings > Privacy & Security.
