Ensure that your Mac Studio connects properly to your Video I/O device:
1. On the Apple menu, select [Shut Down] to shut down your Mac.
2. Turn on your Mac and continue to press and hold the power button as your Mac starts up.
3. Release the power button when you see the startup options screen, which shows your startup disk and a gear icon labeled [Options]
4. Click [Options], then click [Continue].
5. Click [Utilities], then select [Startup Security Utility].
6. Select the startup disk you wish to use from those displayed, then click [Security Policy].
7. After selecting “Reduced Security,” select “Allow user management of kernel extensions from identified developers” and click [OK].
(We recommend making a note of the settings before making changes so that you can restore the previous security policy after you finish using the app.)
8. Enter the administrator name and password, then click [OK].
9. When setting of the security policy is complete, the following window is displayed.
10. On the Apple menu, select [Restart] to restart your Mac.
