airdrop cannot see my mac
I relaunch the same problem as Ycui in a different thread:
1) I can see my iPhone X in AirDrop from my iMac (10.15.7).
2) I can see some iPhones nearby in AirDrop from my iPhone.
3) I can't see my iMac in AirDrop from any iPhone.
4) I have tried to (a) turn off Firewall or (b) turn on Firewall with "Block all incoming connections" off on my MacBook, with no luck.
5) Both MacBook and iPhones are set "discovered by: Everyone".
6) VPN is disconnected
7) my iMac was visible one month ago, i did not change the settings.
iMac 27″, macOS 10.15
