Can you not do that from recovery on external media, just like installing the OS?

- Wowfunhappy 3y agoNope. iBoot doesn't support USB at all (including for OS installation), presumably to reduce the vulnerability surface area. While annoying, this makes sense, as the USB stack is quite complex. Apple Silicon Macs can boot from USB, kind of, depending on your definition of "boot"--they have to first boot an OS from the internal hard drive and then boot the OS on the USB.
