SECOND DISPLAY — INSTALLATION ============================= 1. Drag "Second Display" onto the "Applications" folder in this window. 2. Open Second Display from Applications. macOS will most likely refuse: this app is not notarized by Apple (the author does not pay for a developer account). The app is safe to run if you trust where you got it — the source code is open. 3. Allow it once (pick ONE way): A) System Settings - Open System Settings > Privacy & Security. - Scroll to the Security section; you will see "Second Display was blocked...". Click "Open Anyway". - Confirm with your password / Touch ID, then click "Open". B) Terminal xattr -dr com.apple.quarantine "/Applications/Second Display.app" You only need to do this once per downloaded copy. 4. On first launch, allow Camera and Microphone access. (Change later in System Settings > Privacy & Security.) REQUIREMENTS macOS 26 or newer. UNINSTALL Run this in Terminal to remove the app and every trace it leaves: "/Applications/Second Display.app/Contents/Resources/uninstall.sh"
