I have a Macbook Pro and since I upgraded to Catalina I have lost Bluetooth. The logo is greyed out with the message Bluetooth: Not Available.
Any cures?
I have tried deleting the Bluetooth.plist and rebooting, but still not working.
You do not say what exact Mac /model /year /size /retina /touchbar is this
or
what exact macOS you are currently running?
Since you upgraded to 10.15 have you updated as well to 10.15.1 then onto 10.15.2 ? These would be the delta updates stair stepping your way up. Reinstalling the 10.15.2 combo update on top of your existing macOS has been known to sort certain one-off anomalies. Download macOS Catalina 10.15.2 Combo Update - Apple ...
If however you just downloaded the 10.15.2 full installer it would be a moot point.
I do not see a general BT issue associated with Catalina.
Lets see the output from this Terminal command, copy and paste:
networksetup -listallhardwareports
