Open unsigned applications on macOS Sequoia: Difference between revisions

Revision as of 03:16, 17 September 2024

As of macOS Sequoia (15), Gatekeeper has tightened restrictions on running unsigned applications. The control-click and Open workaround no longer works. This guide demonstrates how to open these applications. Once an app has been opened once, it can be opened normally in the future.

Through System Settings

Try to open the app. A prompt saying '"My Unsigned App.app" Not Opened' may appear.
Go to System Settings -> Privacy & Security. Scroll down to find the app, and an option to "Open Anyway".
Choose "Open Anyway".
Authenticate as an adminstrator.
The app will now open.

Through Terminal

Use the following command on the application:

xattr -d com.apple.quarantine ./MyApp.app
