macOS Sierra - Airdrop disappeared

I had the same issue exactly. Just bought a new mac book pro retina 13'' with touch bar and process advised upgrade after first reboot. Then airdrop disappeared.

I spend almost 1-2 hour with apple chat support.

Normal support, Senior support and even engineers couldn't bring me a solution.

I was waiting final reply by engineers since yesterday. Their offered solution is ''Re-install OS'' .

And they are asking this even without understanding if i am using TimeCapsule or have backup or any sensitive information stored on computer ? Or some activated license issue ?.. Its very wrong advice without asking any circumstances.

Then i found the solution by myself.

Open Terminal under Applications>Utilities folder.

First disable Airdrop by enter this line :

defaults write com.apple.NetworkBrowser DisableAirDrop -bool YES

Then activate it again :

defaults write com.apple.NetworkBrowser DisableAirDrop -bool NO

After from Apple icon click Force Quit and then choose Finder and click Relaunch.

Here we go Airdrop is back. Alternatively of Force Quit you can restart your computer too.

I write as simple as possible to help everyone who had this issue.

Thank You

I have had this prob ever since I had to upgrade to Sierra to run WOW. I had forgotten just how handy that Airdrop was/is.

Thanks again

Thank you rhnlty ! It works !

I could not boot in safe mode (it gets stuck on loading bar for a while without actually booting)

I log as a Guest user and see that airdrop was working for the guest user. Then I tried your method in my own session and boom airdrop is back.

I am not sure but after restarting finder I think airdrop was not clearly visible in finder so I used Spotlight and search for airdrop and then it was back in Finder again.

Welcome to Apple Support Communities, michaelsoe.
From your post, it appears that since upgrading your MacBook Pro to macOS Sierra, AirDrop isn't available at all either in Finder or searching for it through Spotlight. I'll be glad to help you with this.
Try safe mode if your Mac doesn‘t finish starting up -- Safe mode will make sure your Mac starts up correctly. See if you are able to locate AirDrop while in Safe Mode. If there are no issues, reboot normally and test in your own user account.
How to test an issue in another user account on your Mac -- If you're unable to locate AirDrop while in safe mode, use this article to test another user account. Since AirDrop is part of the operating system, this will demonstrate if the issue is isolated to your account, or if it's system wide.

Let me know how that goes and take care!

Thanks you so much! 🙂

after reading so many articles about this problem, yours solution work perfectly!)
