I don't really understand how Airdrop works under the hood, but...
My wife's MBA and my MBP can usually connect via Airdrop (usually). We are both on Capitan.
BUT, why is my transfer rate so slow? We're on the same wi-fi.
I can copy an AVI to a USB drive and copy it to her computer in 1-2 minutes. Airdrop will do the same in about 30 minutes.
Is that right?
