Connect a 2019 IMAC to a 2020 Macbook AIr to extend desktops displays?
Is it possible to connect a 2019 IMAC to a 2020 Macbook AIr to extend desktops? I want to use the Macbook Air as a secondary monitor. I am using the Apple .8 meter thunderbolt3 to tb3 cable, but the arrange icons do not show up under system prefs/display on either computer.
