I’ve osmc on both hdd and usb, can I force apple tv to boot from the usb instead of the hdd ?

Just install OSMC to USB.

USB is checked first before HDD

It should spin down when not in use if your system idles.

ok, I’m loading osmc from usb now but noticed a strange thing, I had composite enabled when I was running from hdd, surprisingly it works from the usb also without the need to set the /etc/X11/xorg.conf file in the usb!
