When paired with an Apple Pencil, they can use their iPad to draw, sketch or write in any Mac app that supports stylus input. For users on the go, Sidecar makes it easy to bring an extended display with them so they can spread their work out over two displays wherever they happen to be.

“With Sidecar, iPad can be used as an extended display for Mac and a high-precision drawing tablet across supported Mac apps.

“Users will appreciate how they can expand their workspace with Sidecar, enabling new ways of interacting with Mac apps using iPad and Apple Pencil.” In its press release announcing the feature, Apple’s senior vice president of software engineering, Craig Federighi, said: (The latter lets you write on your iPad to draw, sketch, or write in any Mac app that supports stylus input.) What does Apple say about Sidecar? Or you can use your iPad as a graphics tablet for drawing with your Apple Pencil. When in use, you can use your iPad to mirror your Mac display or as a second display for additional screen space. I'm not sure I'd be comfortable with that.You’ll also see a control that lets you enter this mode when you hover your cursor above the green traffic light at the top left of a Mac app (on your Mac). Unfortunately no FileVault and auto-login enabled means any data on your Mac mini is super vulnerable, especially since you'll be travelling with it. I'm not sure if the FileVault password can be entered blindly, but I know I wouldn't want to fiddle with that if I was on the road. For Luna to work 'headlessly' you need to set up the Mac to not ask for any login credentials (including FileVault) when it starts up (so auto-login needs to be enabled). The key thing is that before you enter the password, the Mac does not run any other applications, so the Luna desktop software is not running, hence no image is output to your iPad mini and you can't see what you're doing. If you have FileVault enabled, fully powering down the Mac causes it to ask you for the FileVault password when you turn it back on again (could be just your user account password, which then uses Keychain to unlock FileVault). Traditionally you connect to them remotely from another computer with Remote Desktop or VNC, but apparently Luna also calls a setup where an iPad is your only monitor for a Mac mini 'headless'. The term 'headless' is generally used to refer to a computer that is running without a monitor.
