I needed to boot my old iMac into Recovery Mode last night, and I couldn’t get it to work with either my Model 01 or my Atreus. (And I was surprised to realize that other than those two keyboards, a home-built Atreus with unknown firmware, and a half-disassembled Planck, I have no other keyboards in the house.)
I couldn’t get the Mac to recognize the Cmd-R on booting. I tried it with both keyboards on two different Macs (an 8yo iMac and a 2yo Macbook Air), and it didn’t work with either of them.
I ended up fixing the problem by making a bootable USB and using that, but it would be very useful to be able to do this with just the keyboard.
Has anyone else seen this? Is this expected?
