Set up ThreadMyMac

Download the app, open it once, switch on one permission and paste your license key. It takes about a minute.

  1. Download and install

    Open the downloaded file and drag ThreadMyMac into your Applications folder.

    Download ThreadMyMac 1.0.0

    Version 1.0.0, 3 MB. Needs macOS 13 Ventura or later, on Apple silicon or Intel.

  2. Allow it to open

    ThreadMyMac is sold directly rather than through the App Store, so macOS asks you to allow it once.

    1. Open ThreadMyMac from Applications. When macOS says it can't verify the app, click Done.
    2. Open System Settings, then Privacy & Security, and scroll down to Security.
    3. Next to the message about ThreadMyMac, click Open Anyway and confirm with your password or Touch ID.

    If you prefer Terminal, this does the same:

    xattr -dr com.apple.quarantine /Applications/ThreadMyMac.app

  3. Switch on Accessibility

    The welcome window asks for Accessibility, the permission every window manager needs to move windows. Click Open System Settings and turn ThreadMyMac on. It's the only permission the app asks for.

  4. Activate your license

    Paste the license key from your purchase email into the License page and click Activate. Your windows line up on the strip straight away.

    No key yet? Buy ThreadMyMac for $19.

If something doesn't work

  • Windows don't move. Check that ThreadMyMac is on in System Settings, Privacy & Security, Accessibility. If it is, turn it off and on again.
  • Swipes do nothing. Open ThreadMyMac Settings, then Mac Setup. It lists any trackpad gesture or other window tool in the way, with the fix.
  • You got a new Mac. In Settings, then License, click Deactivate this Mac, then activate the same key on the new Mac.
