How is it possible to bring up the new "startup options" on a mac mini or mac pro that is in a distant, locked and cooled data center/IT room, and I only have remote KVM access to it but I am not there physically to press and hold the power button?

I want to be able to select which device to boot from when I reboot the machine on the fly from a keyboard or some other way remotely (like MDM? iLO?), so I can select which boot device to boot from. Is it expected to stand next to the mac with this change for bringing up startup options?

I am really hoping I can still use keyboard or ability to send a command to select boot device remotely.

Pardon me, not sure what the etiquette is. I was told by Apple engineers during WWDC20 to ask questions here and will get answer. Been waiting in the past 3 weeks for an update. Is this the wrong place? What's missing please?

Hi arpadkun,

You can use the Startup Disk Control Panel or 'bless' command in the terminal to set the next boot startup target.

It is a very deliberate thing that you cannot access 1TR unless you have physical access to the machine.
