AirDrop: how to distinguish between iMacs on same network?

[KristenS]

I have three iMacs of various ages. They all have different names in System Preferences > Sharing but if I'm trying to AirDrop something — say a photo from my phone — all three show up in AirDrop as "iMac" with no differentiation. They're all signed into the same iCloud account so the user icon is the same, too. Is there a way to get the Computer Name from the Sharing pane to show up in AirDrop?

So far my workaround is to turn off AirDrop on the iMacs I don't want to talk to at the moment, but I feel like there should be a better way.

For AirDrop, the .local Bonjour name is used. It can be set via Terminal

sudo scutil --set LocalHostName "iMac-Kristen-1"

(no special characters except "-")

Or, via GUI, check the following entries:
System Settings > General > Name
System Settings > General > Sharing > Hostname > Edit (no special characters except "-")
System Settings > Network > [AdapterName] > Details > WINS > NetBIOS name

Any change?

This is weird—the new name appears in AirDrop on my iPad, but not on my MacBook. 🤷🏼‍♀️ Anyway, it worked enough. Thanks!
