Any idea what's causing my kernel panics?
I leave my Macbook with an external 4K monitor connected via USB-C/Displayport.
I come back and it's 'forgotten' I have a 4K monitor.
I unplug and replug - instant frozen screen, then pink screen and restart.
I don't appreciate Tim Cook flogging me an experimental toy as a work machine.
