I'm on a wifi network with a whole bunch of other computers, all of which have AirDrop set to "Allow me to be discovered by: Everyone." (And I do not control these other computers, so I can't go turn off their AirDrop.)
When I open AirDrop in Finder, I see 8 of these other machines' hostnames, but not the specific one I want to communicate with.
Is there a way to show all AirDroppable machines, not just the first eight?
Even better, is there a way to say "I only care about the machine with hostname
foobar; please show me that one"?
I have found two workarounds:
Carry both computers to a Starbucks or something, where there is a wifi network without so many other Macs on it.
Tunnel via what AirDrop calls an "older Mac". (That is, airdrop the files from the source machine to the older Mac, then airdrop the files from the older Mac onto the destination machine.) This works because the newer Mac can see the older Mac only when the latter has its AirDrop window open, and the older Mac can see the newer Mac only when the latter is "Searching for older Macs...". As long as the wifi network doesn't have eight older Macs on it (and all with their AirDrop windows open!), this will work.
