I switched my MacBook airs OS to Fyde about a year ago, but I want to try to switch it back to the Mac OS, but I can figure out how to do it. I’ve tried using the Boot from a drive option on the starting screen, but it doesn’t work. Typically, you would be able to boot from a drive to install a new OS on other platforms like Windows or Mac, but I don’t know how I would do that with Fyde.
Booting an OS on a particular device usually has nothing to do with the existing OS. With an (earlier model) of Macbook Air, it’s usually pressing alt key whilst booting up to bring up the bootable media selection screen, then you can select a USB bootable device with your desired OS flashed onto it.
