Airdrop was amazing when it first came out with MacOS. It really just worked. Our lab of mostly Mac users stopped using USB drives to share stuff.
Then they released a new version of it to be compatible with iOS and enable all the continuity and handoff stuff.
Then all the problems started. It simply wouldn’t work. Devices couldn’t be discovered, files couldn’t be sent. Handoff would eat half written emails. The problem was due to the replacement of mDNSresponder with discoveryd which they eventually rolled back.
In fairness it’s been fixed for some time now and I’ve got no more problems with it.
