The iPad Pro has a gorgeous display, so it makes sense to want to use it as a wireless display for your computer. The Luna Display dongle can help. It is a clever tool that turns your iPad Pro into a second display for your Mac Mini. It is available in USB-C and Mini DisplayPort versions.
As soon as you activate Luna, you will be able to run macOS on your iPad. You can interact with your apps using Apple Pencil and simple touch gestures. Connection is made over WiFi.
