Topaz Photo AI [v3.4.1] on [Mac mini M2 Pro Sequoia 15.2]

Apple photos plugin functionality is not great to begin with. I constantly run into issues even with just straight JPG’s, where after processing in PhotoAI I am unable to save it back to Apple Photos.

Hello @pascal-6073

If the files were shot on iOS 18, Apple changed the way they encode metadata, and this creates issues in multiple programs, such as Topaz.

  • Until the development team supports the new way Apple encodes metadata, you can convert the HEIC files shot on iOS 18 to JPEG, or TIFF, or you can revert to iOS 17.
  • You can also make sure, if you stay on iOS 18, to put your settings to shoot in JPEG, not HEIC.

The development team ticket working on the support of this new encoding, and we can circle back here once it is officially supported!

Errm, no. Apple doesn’t sign any iOS 17 version anymore (at least on the iPhone 15 devices) thus making a downgrade impossible.

There is ways to downgrade, however its complicated. Make sure to turn your files to JPEG or TIFF until we support this new encoding.

This issue thread was closed for comment automatically, but I believe the issue is still open (thread is still noted as investigating):

HEIC photos will not open in Photo AI 3.2.1 from Apple Photos)

Is there an ETA for a fix please? Thanks


Topaz Photo AI [v3.3.3] on [Mac]

I should have mentioned, I am getting the same error when opening HEIC files from a local linux file share (not directly from apple photos)

Please could an update be provided on this open bug that is a showstopper for using the product with a common file type.

After upgraded MacOS to Sequoia 15.0 and Photos apps upgraded to 10.0.

Steps to reproduce issue:

  1. Open Photo
  2. Click Edit button on top right corner
  3. Click Extension option
  4. Click Edit in Topaz Photo AI
  5. Error message prompted:
    “Cannot open Apple Photos Image.heic
    Invalid input: Unspecified: Metadata not correctly assigned to image”"

I tried delete the Photo AI and reinstall. However, the problem still existed.

Topaz Photo AI [v3.2.1] on [Mac]

Please follow the instructions below to perform a clean install to troubleshoot better why you had this problem with Topaz Photo AI:

  1. Be sure you have fully closed any plugins, such as Lightroom Classic, Photoshop, etc.
  2. Clear any previous plist files on your computer for Topaz Photo AI | Topaz Photo AI | plist Files Mac
  3. Disable any antivirus, firewall, VPN, or proxy software that might be active on your computer. These tools sometimes interfere with the installer’s ability to download the model files.
  4. Ensure that the Topaz Photo AI installer has all the proper settings in your system by going to your Mac System Settings > Privacy & Security tab and scrolling down to the security section. You will want to make sure you have ‘App Store and identified developers’ selected | MacOS | Example of Proper System Preferences
  5. Rerun the installer. You can download a new installer from your account’s download page | Topaz Labs | My Account | Download Page

Let me know how that goes for you and I’ll keep an eye out for your reply.

I’ve never seen this one before. I dragged an image from my iPhone to both PAI and PAI Beta and they returned the same error message:

Cannot open

B44E-OF96CFEBAE7D.heic

Invalid input: Unspecified: Too many auxiliary image referencesPlease describe your issue here. Try to include logs (Help → Logging) and add screenshots if necessary.]

Steps to reproduce issue:

  1. Step 1. Take photo on iPhone 15Pro
  2. Step 2 Attempt to open in PAI (both beta and current version
  3. Step 3. Receive error message.

Topaz Photo AI [v1.x.x] on [Windows/Mac]

I have the same issue. Followed the steps by John S, problem persists. Kindly help please!

This behavior started again suddenly.


There was an update to 3.2.1 so I updated and tried again.

Steps to reproduce issue:

  1. Edit a photo in Apple Photos
  2. Select “Edit in Photo AI” from the plug-ins menu
  3. Photo AI opens
  4. Photo AI generates a message that it cannot open this file.
  5. Click OK and Photo AI shuts down

PNG and JPG images open OK, just not HEIC.


Topaz Photo AI [v3.2.1] on [Mac]. MacOS 15.0

Can you edit them if you use TPAI in standalone mode? I certainly can (sorry, I don’t use Apple Photos so can’t test that for you). Given the concerns about the new EULA, I am still on v 3.2.0!

OK, I set up Apple Photos to see what happens for me.Is this the correct way to send to TPAI?


If so, I notice that the HEIC is converted to a TIFF, but then the image won’t save back to Apple Photos. Maybe I am not doing this right!

We do support HEIC; however, it is important to note that we do not support ProRAW files.

There have been a few users who have reported that Apple’s recent iOS update has changed the way they encode HEIC files, which has created some problems.

To help the developers investigate why this might be occurring and to find a solution to this issue would you mind sharing a HEIC file that you are having trouble using with Photo AI?

You can securely submit your image(s) to my Dropbox using the link below.

Dropbox File Request

Please be sure to send me a note to let me know if you send something.

I’ve added this ticket to a support ticket we opened with our development team. I will contact you once this issue has been resolved and update you on this email thread.

In the meantime, the current workaround would be to convert those HEIC files to either JPEG or TIFF .

Let me know if you have any other questions in the meantime and I will be sure to keep you updated :slightly_smiling_face:

The dropbox link doesn’t seem to work for me, I just get a blank browser screen. I tried to send two photos but the email was bounced back. This one image is 2.4MB, so I hope this gets to you…

Also, note that for images shot with my iPhone 14 Pro and Pro Max, they seem to work OK with Luminar Neo, either as an Apple Photo extension or “standalone”. This is just happening with photos from my iPhone 15 Pro.

Thanks,
JE

Dropbox servers were having issues yesterday; this has now been resolved. Would you mind trying the Dropbox link above again?

Please be sure to send a note when you send something in.

I will note that the iPhone 15 ProRAW files are not currently supported by Photo AI. However, our development team is currently investigating an issue with the most recent iOS update. Were these images taken with an iPhone using the latest iOS18 update?

Thanks, I uploaded two photos that won’t open to your DropBox. Neither are Raw files. Yes, I took the photos with iOS 18 on my iPhone 15 Pro. It was version 18.0. I haven’t upgraded to 18.1 yet.

The two images I uploaded into your dropbox:

IMG_0614 as exported.heic: this is the image exported from Apple Photos.
IMG_0614.heic: this is the original image without edits from Apple Photos Neo.

Both generate “Invalid Input: Unspecified: Metadat not correctly assigned to image"

Cheers,
JE

Thanks for sending in those files. I’ve added this information to an ongoing support ticket we have open with the development team, who are investigating this problem with the recent iOS update and HEIC files.

We will be sure to reach out to you on this forum thread once we have released a new version that address this problem.

In the meantime, if you have any other questions please feel free to send us an email at help@topazlabs.com
