No Boot Menue M1 Mini
I have Mac M1 Mini 2020, it was working fine With Montery 12.6.3, As I want to degrade it, So I formatted the Os and tried to boot with the external bootable drive ...Now the problem is, I am NOT getting the BOOT MENU. I Hv already tried long-pressing the Power key , Nothing appears on the screen and white light keeps on breathing just after the on sound. As soon as I release the power button Light goes orange and keeps blinking for long time and nothing happening..Apple care was also unable to update its firmware...
