Headless Mac mini M2 Pro macOS update requires user interaction

Trying to update to MacOS 27.2 on a headless MacMini that boots from an external NVMe drive.


MacMini M2Pro

MacOS 27.0.1

Is a headless setup and boots from an external 2TB NVMe (i.e. Startup Disk is an external 2TB NVMe in a case)


Any attempted upgrade to MacOS 27.2 always reports "User interaction required" (even after running "sudo softwareupdate -i -a -R" in terminal and rebooting).

Does this mean I have to actually haul a terminal/keyboard/mouse over to the headless MacMini and do whatever "user interaction" is required?


Lame.

If Screen Sharing gets you to the Mac desktop, try running Software Update there while signed in. This update may need an on-screen approval or restart prompt that the terminal command cannot finish. If the prompt is not visible remotely, connecting a display and input devices once should show what it is waiting for.

It may. There are limits to what can be done remotely. Screen Sharing requires a system that's fully operational; I have my doubts that it would work if/when the update/upgrade process requires user input.


FWIW, I have also always found it best to update/upgrade Mac minis using a wired keyboard & mouse.
