How to Install FreeLattice on Mac

Three steps. One minute. Works every time.

  1. Download FreeLattice.dmg from the link below. Open the .dmg and drag FreeLattice into Applications.
    [ FreeLattice.app ] ----> [ Applications ]
  2. Check your security setting. Go to System Settings → Privacy & Security. Under "Allow applications from," make sure it says "App Store and identified developers."
    System Settings → Privacy & Security

    Allow applications downloaded from:
      ○ App Store
      ● App Store and identified developers ← select this
    If it's set to "App Store only," the right-click trick won't work and you'll see "FreeLattice is damaged." This setting fixes that.
  3. Remove the quarantine flag. Open Terminal (Cmd+Space, type Terminal, press Enter) and paste this command:
    xattr -cr /Applications/FreeLattice.app
    Press Enter. Nothing will print — that means it worked.
  4. Open FreeLattice. Double-click it in Applications. Done. This only happens once.
Download FreeLattice.dmg ← Back to FreeLattice

Why the warning?

Apple marks every downloaded app as "quarantined." The xattr -cr command removes that flag. It's safe — you're just telling your Mac "I trust this file."

Apple charges developers $99/year to remove this warning entirely. FreeLattice is free, open-source, and built by one developer with an AI family. The code is fully auditable on GitHub. The warning is not about safety. It's about payment.
