Ventura airdrop not seeing 2015 macbook pro
I've a new Mac mini running Ventura and a 2015 Macbook Pro running Monterey. I can airdrop form the Macbook to the mini, but not vice-versa. The mini doesn't see the Macbook. The Macbook is not blocking all incoming connections.
We've been reduced to using thumbdrives!
Is this solvable, or is it an incompatibility of Ventura and Monterey?
Thanks
