I've got myself in a spot of bother on my PI4. I set up omxplayer to play a video on repeat at startup not realizing that I wouldn't be able to interact with it - meaning I cannot close it.
I've tried blindly launching terminal in the background with CTRL+ALT+T and typing "killall omxplayer", it didn't work. I also tried "sudo killall omxplayer" but this also did not work.
I also tried plugging the SD card into my macbook and editing the boot text file, but it doesn't look like OSX is able to write to whatever filesystem the card is formatted in.
Unfortunately my PI doesn't have SSH enabled either.
I was hoping that there was a key combo I could press at startup to send me straight to the shell, but from my research it doesn't seem like there is?
