AirDrop conitnually Failing between iPhone and MacBook

Same issue, I've used Airdrop on this Mac Studio hundreds of times to upload photos ... now, after the latest Sonoma upgrade (14.4.1 to 14.5) it doesn't work. I've done the defaults write to com.apple.mDNSResponder.plist thing, I'm not using a VPN, and I've looked for other computers with a similar name in my AirDrop list of devices (all various 'fixes' that people have mentioned in this thread), but none of that worked or was applicable.

I did monitor my Console while trying to send something and found some timeout errors, but don't know how to interpret them:

Failed to resolve peer device 'IDS 599E8B32, Nm 'Mac Studio', Md 'Mac14,13', SF 0x80000A0302 < BLE DuetSync WiFiP2P Friend Owner AirDropUsable >, DFl 0x1 < Info >, AcLv = Screen (7)'. Error - Error Domain=RPErrorDomain Code=-6722 "kTimeoutErr (Request timed out before send)" UserInfo={cuErrorMsg=Request timed out before send, NSLocalizedDescription=kTimeoutErr (Request timed out before send), cuErrorDesc=kTimeoutErr (Request timed out before send)}

Just before that is:

### Session start send failed: Service com.apple.sharingd.AirDrop, PeerID 599E8B32-B55D-4785-A0ED-9AD550D9165A, CSID 0x6D01D41B, kTimeoutErr (Request timed out before send)

and before that (from the AirDrop process):

Failed to log access with error: access=<private>, error=Error Domain=NSCocoaErrorDomain Code=4097 "connection to service with pid 250 named com.apple.privacyaccountingd" UserInfo={NSDebugDescription=connection to service with pid 250 named com.apple.privacyaccountingd}

and before that, three things, all from the Airdrop process, related to CAML:

CAML error:47: `o' element must have `type' attribute

CAML error:47: Unknown value element `LKEventHandler'

CAML error:47: No such class `LKEventHandler'

I have the same issue. Sonoma 14.0, and 17.0.0 on 14Pro. I can Airdrop FROM MBP to iPhone, but not the reverse. Airdop of anything large or small fails from phone to laptop.

Yea, I realized I hadn't written down phone was on .0.3, but it is. I toggled AD on & off on both devices, and did the trusty reboot on both too.

The phone sees the laptop as a destination, along with other iOS devices. When I select the MBP, the AirDrop just fails after some time. I feel like it's Sonoma.

I have similar issue, Macbook pro 14" MacOs Sonoma and iphone 15 promax iOS 17.0.3, see each other, iphone can send to macbook, macbook can send small image to iphone, but a MOV video file ~500MB, the transfer was good until in the end, it show "failed" on iphone and "cancel" on macbook

Same issue. Since updating my computer and phone to current releases, airdrop continuously fails. Have tried restarting both devices, disabling and re-enabling airdrop on both ends, turning bluetooth off and on, and still fails.

It worked seamlessly prior to updating my computer and phone.

It is Sonoma 14. I tried everything bbesspete recommended and every other response in this thread. I googled and did many things, but it boils down to the laptop and Sonoma 14. Are we going to have to go to the previous iOS? Before the iOS update, I could do everything just fine. Now what?

I am experiencing persistent AirDrop issues on my iPhone 16 Pro (iOS 17.0.3) and both my MacBook Pro 14” (Sonoma 14.1) and MacBook Air 13 M2, disrupting my workflow for over six months. Despite exhaustive troubleshooting, including Wi-Fi and Bluetooth resets, software updates, and even system reinstalls, the problem endures. The items are recognised, I just always get a “failure” notice. The correct device name appears for AirDrop etc. Very occasionally a duplicate listing with an incorrect icon allows file transfer, hinting at a systemic inconsistency. This issue has not only persisted across different phones but also through recent software updates and even after a complete reinstallation of the operating system on my MacBook Pro.

I have the same problem since updating my macbook air M2 to Sonoma. I can't Airdrop from the macbook air (MacOS 14.1) to a macbook pro 2016 with Monterey. It is working in the other way, from the macbook pro to the macbook air...

Glad it fixed it for you. I’ve updated to 14.1.1 and

1. airdrop doesn’t work
2. External USB drive no longer works (on two separate 14.1.1 machines)
3. internet drops regularly. ( I don’t mind blaming the router for this but with the other two items, it’s a bit suspicious)

I'm having this exact same issue of not being able to airdrop from my iPhone to MBA M2 after upgrading to Sonoma 14.2.1 from Ventura yesterday. The other direction (Mac to iPhone works though). Everything was working fine before upgrading to Sonoma.

This fix worked for me. When AirDrop failed going from iPhone to Mac, I noticed that the Mac Airdrop icon was generic. After running the sudo command, the Mac Airdop icon switched to my current wallpaper.

Tried everything else in this thread and it didn't work for me. Thanks Blade 996 and Arman Rajabzadeh!

Hi this has started happening to me too since i bought a 15 Pro. Airdrop constantly fails between my phone and my Macbook Pro. It has ALWAYS worked previously. I have followed all online suggestions about rebooting both devices, turning bluetooth and wifi off and on again.....nothing works and it is really frustrating...kinda negates buying Apple products for the interoperability....PLEASE HELP!

Hi again, looks like I spoke too soon. Worked last night after I followed the instructions but went to Airdrop a particularly cute photo of my husky from my phone to my Macbook and it kept failing. I am not particularly technical anymore but could you tell me what that line of code is supposed to do and what the actual issue is that prevnts this from being its normal reliable self please? Thanks!

Who else gets excited to know they can spend oodles more money than the ordinary people pay who buy ordinary devices only to discover that their devices -- not to allow any confusing antecedents here, by "their" I mean the devices of those of us giddy enough to buy Apple products -- are replete with bugs. Not just any bugs, but APPLE bugs. These bugs are extraordinary because they can inflict a harsh sense of "WTF?!?!" and "Not AGAIN!?!" and a whole host of other perplexing and annoying emotions.

It makes me laugh to be told, when Airdrop repeatedly fails to function, "Every now and then you just need to reboot your devices." Really? How simple. Who'd a thunk.

Well, tell you what. REBOOT this! <insert gif of penguin staring at monitor whilst excitedly typing S-A-M-S-U-N-G on the keyboard>
