Well.... sidecar is in system properties. It appears to be working...
sadly I don' t have the hardware to check...
I have it in system preferences, no problem. It even appears on the top ready to connect. However, when I select my iPad it inevitably times out whatever I do. I've tried:
* Numerous updates for kexts and/or plugins.
* Numerous updates to macOS (from 10.15.1 up to 10.15.6)
* Numerous iPadOS updates
* "Reset network settings"
* Sign-out and sign-in on all devices
* Changing brcmfx-country codes
* Changing SMBIOS to MacBookAir 2018
Meanwhile, my iPhone shows ready for an instant hotspot, but times out as well.
Import from iPad and iPhone both show up, but do not work. (time-out every time)
iMessage DOES work
Hand-off DOES work
Continuity DOES work
Copy/paste between devices DOES work
AirDrop DOES work (Albeit it takes a long time to discover the laptop...)
Generally speaking, bluetooth is somewhat problematic - where my MX Master3 mouse sometimes looses connectivity for a few seconds - and then "catches-up" on any actions I've taken with it.
.... suffice to say I am completely baffled! Any advice will be very highly appreciated.
happy hacking!
