I’m keen to get started with RancherOS on a group of Intel NUC6CAYH devices. I’ve downloaded rancheros.iso v1.5.1 and used balenaEtcher to create a bootable USB drive from my Mac. The USB drive is not appearing in the boot menu. I also tried versions 1.4.3 and 1.3.0.
Any tips on booting correctly would be much appreciated.
