I'm attempting to install Arch onto a 2016 Macbook pro - however when the actual installer prompt starts, the screen buffer overflows below the bottom of the screen. As a result, the active prompt is being rendered somewhere below the visible screen, and I can't see what I'm typing nor what the response is (until I press enter a bunch of times to move the text up).
Is there any way to reduce the number of rows the installer terminal renders? I've tried using the vga command line setting in GRUB, but that so far has had no effect.
EDIT: I should mention I have also tried changing the font via setfont - while this does change the font size, the installer still runs off the bottom of the screen once it is reached.
