Installing Snaggle ================== 1. Drag Snaggle to the Applications folder. 2. Open it. macOS will say Snaggle "is not opened because it is from an unidentified developer" (or cannot be verified). This is expected: Snaggle is free software and is not signed with a paid Apple Developer certificate. 3. Open System Settings > Privacy & Security, scroll down to Security, and click "Open Anyway" next to the message about Snaggle. Confirm with your password or Touch ID. (Control-clicking the app and choosing Open no longer works on macOS 15 and later - Apple removed that shortcut.) 4. Snaggle needs Screen Recording permission to capture anything. The first capture triggers the request; enable Snaggle under System Settings > Privacy & Security > Screen Recording, then quit and reopen the app. Snaggle lives in the menu bar, not the Dock - look for the viewfinder icon. Prefer the terminal? This removes the quarantine flag in one step: xattr -dr com.apple.quarantine /Applications/Snaggle.app Snaggle is free software under the GNU GPL v3. Source:
