Greetings gemara2,

For help transferring photos from your iPhone to your Mac, follow the guidance found here:

Transfer photos and videos from your iPhone, iPad, or iPod touch to your Mac or PC - Apple Support

"Import to your Mac

1. Connect your iPhone, iPad, or iPod touch to your Mac with a USB cable.
2. Open the Photos app on your computer.
3. The Photos app shows an Import screen with all the photos and videos that are on your connected device. If the Import screen doesn't automatically appear, click the device's name in the Photos sidebar.
4. If asked, unlock your iOS or iPadOS device using your passcode. If you see a prompt on your iOS or iPadOS device asking you to Trust This Computer, tap Trust to continue.
5. Choose where you want to import your photos. Next to "Import to," you can choose an existing album or create a new one.
6. Select the photos you want to import and click Import Selected, or click Import All New Photos.
7. 
8. 
   
9. Wait for the process to finish, then disconnect your device from your Mac."

Take care.

I'm getting the same error. Here are the specs of the devices involved:

Computer: iMac (27-inch, late 2012)

macOS: Mojave 10.14.6

Phone: iPhone XR

iOS: 16.0.2

ImageCapture version: 8.0 (1106).

One additional detail I've noticed is that ImageCapture seems to succeed in transferring images that are not photos (e.g. screenshots or images downloaded from other apps), but fails at transferring any photos shot using the iPhone's own camera. (And FWIW, I have the phone configured to save photos in JPEG format, not HEIC.)

I get the same error gemara2 reported (9956). I get this when trying to import pictures from my iPhone XSMax since upgrading to iOS 16. I see picture previews on my Mac and I can delete the photos from my Mac - I just cant import the photos to my Mac. I get the error on my Mac Pro running Mojave, my Wife's iMac Running High Sierra, and the old iMac running El Cap in my basement. I get the error regardless of account login, and I get it across Photos, iPhoto, Aperture, and of course Image Capture. I've tried monkeying around with setting the phone to download compatible or original pictures. I can email, air-drop and iMessage the pictures just fine. I can import the photos by attaching the iPhone with USB to a Windows 11 computer using their standard camera import tool. On the first try I saw a small dialog box that asked me to update a driver on my mac for my iPhone. When that import failed, I tried again on my wife's computer - and refused to install the update when it asked for that. Both with and without updated driver failed, and then I allowed my wife's computer to install that update too. Still failed. The old iMac with ElCap did not ask to install or update a driver for my iPhone, but it failed in exactly the same way. Airdrop isn't so great for me because my network is wired. But - here's another workaround: Open Files on the iPhone and attach to your Mac (e.g. smb://MyMac.local) Then go to Photos, select the ones you want and "share" the pictures to Files - the Mac drive will show up there and it will dump the photos onto your Mac.

gemara2,

Thanks for clarifying this. We'd recommend that you connect with Apple at Apple Support for further guidance.

Take care.

And to clarify: like gemara2, this problem only started happening for me after my phone automatically updated itself to iOS 16.

Having this error also!

I am also now getting this message after having upgraded my iPhone 11 pro to iOS 16

I too am seeing this problem. After years of successful photo imports, I now cannot import my photos after I upgraded my iPhone to iOS 16.0.2.

So I was getting the (Error- 9956). I needed a work around because backwards compatibility ain't a thing. So I used Airdrop and imported the photos from there. It work!

I can confirm that the 16.1 update fixed this problem for me. Everything works again - everywhere. :-)
