Sidecar is greyed out in System Preferences.
I'm using a current iMac (9th gen 6 Core i5) and a current iPad Pro.
The iMac is on Catalina and the iPad on 13.1.2
Sidecar is greyed out.
I've tried restarting the Mac and the iPad too.
I use ethernet with the Mac, but have switched over to WiFi and checked that the iPad is on the same network.
I've also tried a USBC cable between the iPad and iMac.
Nothing.
Anyone else having the same experience?
What magical incantation am I missing?
