So I’m following Mr Macintosh’s video on installing Sonoma onto unsupported Mac, in my case it’s a mid 2012 MBA w Catalina. I follow everything he says but when I come to reboot after downloading the sonoma installer, my “recovery” screen does not offer an “EFI Boot” icon. I only have this “macOS utilities” screen which offers the following options: “Restore from Time Machine Reinstall macOS (Catalina) Get help online Disk utility”. Am I missing something? (In the video he’s doing it on a high sierra machine, and easily copies the high sierra installer onto his usb partition through the terminal commands. This does not allow me to do the same with Catalina after I type “sudo” into the terminal.)
Any advice greatly appreciated!
