Ubuntu Version: 24.10
Desktop Environment (if applicable): Unsure. Can be provided if I’m told where to look!
Problem Description: When I first got my MacBook, the in-built keyboard and touchpad worked as expected. After installing Ubuntu, neither the keyboard nor the touchpad have ever responded to any presses
Mice and keyboards plugged into external docking stations have always worked as expected
Ctrl+Alt+F3 into a virtual terminal and typing does not result in a working keyboard
I have found https://askubuntu.com/questions/1282260/on-board-keyboard-and-trackpad-not-working-20-04/1282269, but the underlying issue was fixed in 2020?
I have seen https://askubuntu.com/questions/1506951/laptop-keyboard-not-working-when-trying-to-install-ubuntu-23-10
The laptop has been restarted many times. I have upgraded to Ubuntu 24.10 today, but the keyboard and touchpad are still unresponse
Relevant System Information: MacBookPro 16.1
