Airdrop does not work after MacOS 13.2 and iOS 16.3 updates
My iMac is 2020 build. I have the latest updates, plenty of memory. Wifi working, Firewall set up and settings to accept transfers from "contacts only" and tried "everyone". Multiple issues when I check settings on my iMac and iPhone 11 Pro Max.
Basically after the update I could no longer transfer photos from my iPhone to my iMac via Airdrop.
Finder shows AirDrop recognizes iPhone. My iMac is found on the phone's bluetooth but when I go to connect it "xxxxx iMac is not supported. Just once yesterday it did give me the code to use to pair the devices but after I tried to pair them, it gave me the same error message.
Another issue, I can go into my phone settings and change them back to where they were for AirDrop to work. Even after I hard boot both devices those setting changes go back to what they were before they were changes, preventing any kind of transfer.
I suspect this is from my choice to choose the new iOS 16 policy for higher security on file transfers.
Any ideas or suggestions on how to fix this?
