试试 Luna Display Yes, it is possible to use your iPad as the only display for the Mac mini after you complete the set up for Luna Display. Please note, an external display will be needed during the initial setup process for Luna Display.
If you'd like to avoid using an external display every time you turn the Mac on, you will need to set your Mac mini up for automatic login and disable FileVault. This way when you shut off your computer and allow it to restart any apps upon bootup, your Mac Mini will just autologin and run the Luna software at startup.
