USB screen mirroring not working

Check the connection first, then whether macOS allows Rotato to access the connected device.

Check the phone and cable

Use a data-capable USB cable, unlock the phone, and accept the trust prompt when it appears. Check whether the phone is visible in Finder.

Check camera permission

Open System Settings → Privacy & Security → Camera and check Rotato's permission. If changing it requires restarting the app, save your project first and follow the macOS prompt.

Compare with QuickTime Player

Open a new movie recording in QuickTime Player and inspect its input menu. Check whether the iPhone appears as a screen source.

If neither app can see it, focus on the USB connection and device permissions. If QuickTime can see it but Rotato cannot, send support details, including your macOS and Rotato versions.
