When I go to create a MacOS installer of like Catalina nothing happens on version 3.6. So I downloaded version 4.0 (40059) and it gives me an error saying, “There was an error creating the bootable disk on /Volumes/MyVolume. Please verify that the disk is not write protected and that the macOS installer is not in a protected location.”
When I run this command in the terminal:
“sudo “/Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia” --volume “/Volumes/MyVolume” --nointeraction”
I get this error:
Maybe something changed on the M1 Macs where we can’t create pre-BigSur Installer anymore?

try
nothing changed
Unfortunately both of those commands give the same error as before: “zsh: killed sudo --volume /Volumes/MyVolume --nointeraction”
I have found others here in this discussion at the link below having the same issue I am having. So I think its broke on M1 Macs
I repair Macs, and thus I often need a bootable installer for various macOS versions. I just upgraded to an M1 Macbook Air, and it appears I'm no longer able to use the "createinstallmedia" command line app: it errors out on "Killed: 9":
The same...
I have not looked into it yet, but it does seem to be broken on M1’s. So much new.
