Why is AirDrop transfer failing?

I am having the same exact issue, my girlfriend's Macbook Pro can send files to my MacBook Pro (same year) but I cannot send them to her?

Same issue here.

Exactly the same problem from a Mac Mini Early 2010 to a MacBook Pro 13" Early 2011 (Lion, french).

Everything worked fine until the copy of a big file from an external drive failed.

Now I have the message : «Le transfert a échoué. Reéessayez».

Still works fine from Macbook Pro to Mac Mini.

Anyway to restart Airdrop ? Or check Preferences ?

Another post says that one should force quit Finder on both machines, and then it will work. This is what I did, and it did work after not working for a few days.

Having the same issue. Airdrop was working a few days ago, now all of a sudden sending files from my MBP the transfer fails, but when my gf sends me a file from her MBP it goes thru right away, and works the way its supposed to.

I have tried restarting, and relaunching Finder, but to no avail.

using a USB key for now.... 😐 😠

I too had the same error in Console. Following the suggestion to Force Quit Finder, I relaunched Finder on both systems. Now I can connect. I have a feeling that if a computer has slept for a while it ends up with an old SSL certificate of some sort and it will fail against a newer one. Or some nonsense like that.

Anyway... I now have a 16GB file transferring over (an Aperture library), bypassing my server, and it is rather nice.

that worked perfectly!! Thanks a lot!

Force to quit finder in both computers and it will work fine, I just did it!!!

Sorry but how do you force quit finder? No option while right clicking?

Option and Right-Click on the Finder icon in the dock to find "Relaunch" in the pop-up menu.

Go to apple logo and make click. There is an option force to quit.

A dialog box appear with all your programs open. Select finder and make click on relaunch button. That will close and open Finder.

You are right. Go to apple logo and select force to quit in the dialog box select finder and click on relaunch button. That will work. Do that on both computers.

I have the same issue between my late 2010 iMac and my late 2011 Macbook Air.

When I try to send from the iMac, everything works as normal. When i try to send from the Macbook air, I get the norwegian translation of "transfer failed, try again" (Overføringen mislyktes. Prøv igjen.).

I have tried to flash the finder and restart the computer but nothing happens.

In my case, the problem was resolved by restarting the iMac (the resceiving computer).

Same here. Even after force quit the finder on both Macs I'm only able to copy files from one machine to the other but not vice versa. Have this issue since LIon came out.
