Godot Exported Game Blocked on macOS: Developer Cannot Be Verified

Share
Workaround available macOS Updated November 14, 2026Based on 3 user reportsHow we research

Quick answer

macOS only runs signed and notarized apps by default. Notarize with an Apple Developer ID, or tell players to right-click Open or remove the quarantine flag.

Most likely fix: Sign and notarize

How to fix it

Try these in order — the most common fix is first.

  1. 1. Sign and notarize

    1. Join the Apple Developer Program and create a Developer ID Application certificate
    2. Set it in the macOS export preset and enable notarization
    Did this fix it?

  2. 2. Ad-hoc sign without a developer account

    1. Choose Built-in (ad-hoc only) for codesign and disable notarization
    2. Players will still need the workaround below
    Did this fix it?

  3. 3. Player workaround

    1. Right-click the app and choose Open, or allow it in Privacy & Security
    2. Or run xattr -cr on the app in Terminal to clear quarantine
    Did this fix it?
