Ok so I may have bricked one of my MacBook Airs.
I am writing this post from the MB that's working. I have another one with a dead display. I connected them by Thunderbolt and mounted the broken one as a disk onto the working one using Target Disk mode. Then I used the disk utility to reformat the drive as APFS, Guid Partition. Then I tried to install Catalina but it says "You may not install to this volume because it's a Mac in target disk mode" (see screenshot.)
Have I created an irrecoverable situation?
The only solution I can imagine is to remove the HDD from the bum Mac, put it into the working Mac, install Catalina that way, then put the drive back. Both Macs are out of warranty so it's whatever... but I'm wondering there's a less messy way to get myself out of this hairy situation?
