Administrators Hervé Posted August 9, 2017 Administrators Share Posted August 9, 2017 macOS Sierra and later no longer allow all apps to run by default. Instead, GateKeeper protection was beefed up and it now limits execution to apps downloaded from AppStore or AppStore & identified developers. As such, some downloaded apps cannot be executed without triggering a warning and users may have to go to the Security & Privacy PrefPane to allow the app to run. To change his and allow execution of all downloaded apps by default, type the following Terminal command: sudo spctl --master-disable The restriction will then be lifted and all downloaded apps will be allowed to run. I believe this info was 1st reported by Netkas. Link to comment Share on other sites More sharing options...

Example in Sequoia 15.7.7: Link to comment Share on other sites More sharing options...
