Target Display Mode - Thunderbolt 3 HP ZBook
I have a late 2012 iMac and a HP Zbook with thunderbolt 3. I want to use the iMac in target display mode. I bought an official Thunderbolt 3 to thunderbolt 2 adapter and an official thunderbolt 2 cable. All software is up to date. But I can’t get the iMac into target display mode using the Cmd-f2 button press.
Any advice?
