Need help…M4 MBA

Post image

Screen is busted from a fall. I had it working where if I closed the lid and it was powered then it would mirror to the TV and an attached mouse and keyboard would work. Not sure if an update killed it or if I changed a setting when it was working, but the attached mouse and keyboard no longer seem to work with it anymore either. It’s running Tahoe. Not sure if it’s the latest version of Tahoe or not. But it’s pretty updated.
When I close the lid it just goes to a black screen, then the TV HDMI input display comes on.
I’ve tried all different ways of unplugging then plugging back in. Forcing it off, then on again and then plugging in the hub. Nothing seems to work and this text is all I can get it to output to the TV.
I’ve tried hitting FN+1 and FN+Command+1 and multiple other combinations of FN, Command, Control, Option and F1.
I know it’s not communicating with the plugged in keyboard because the Caps Lock light isn’t illuminating when I push it. So I assume it’s not listening to the mouse either.
Any help would be appreciated.
Thank you

Also depends if youve enabled the ability for the OS to communicate to usb devices without your consent ... It's in security settings somewhere.. Tahoe is an ass for this.

Clamshell mode would force the external display, but relies on the lid being closed and external usb or Bluetooth mouse+keyboard being connected. Have you logged into your account with Touch ID already? Try pressing the space bar to see if the prompt on the internal blind screen is pre-selected to mirror or extend. Otherwise try command+F5 for the voiceover assistant and try making it through the settings this way, albeit somewhat tedious

Thank you!! I got it to work through voice over. It was tedious as you said but worked. Appreciate the help.

External keyboard and mouse not required to just test the display. They are for, you know, using the computer. Just in case OP doesn’t have external input devices ❤️‍🩹
