The Firmware updater "KSMK3Updater" does not work although I did everything exactly as described in the installation description. System: Mac mini, M1, 2020.
Can you describe "does not work"? Any error messages would be helpful. Have you tried different ports on the Mini, I found the front ports worked ok but not the back thunderbolt ones. That's on an M4, but might be the same on the M1.
