What I have done so far:
- installed latest beta of Catalina on my Early 2016 Macbook 12
- installed iPadOS on my iPad Air 2
- Logged out of icloud on both the devices, restarted, logged in on both the devices, restarted.
- Connected ipad and mac through the lightening cable supplied along with the iphone (and a USBC to USB dongle)
- Connected on the same Wi-Fi network
- Connected with bluetooth
- iPad shows up on finder and music
Still I am not able to see the Sidecar menu on the preferences screen. When trying to open through spotlight search, I get an error message.
"It is not available to you at this time. To see this preferences pane you may need to connect a device to your computer."
Any help on what can I do further?
