We are continuing to investigate and improve compatibility with Apple M6 machines running macOS 27.
Our initial findings with v1.7.1 suggest that the app may appear frozen during the first image analysis, when it is actually taking significantly longer to initialize the AI models.
Depending on the image size and models being used, the initial load may take 15–30 minutes. Once the models have loaded and their cache has been built, subsequent processing should return to normal speeds.
These initial loading times are not expected behavior, and our development team is actively working to improve them. If you’re experiencing this issue, try allowing the initial analysis to complete and let us know whether processing improves afterward. If the issue persists, share your app logs with our Support team. Your findings and logs will be forwarded to our development team as part of the ongoing M6 compatibility investigation.

It took 16 minutes for the initial analysis of the photo when I opened a photo in the standalone app. When I opened the second photo the time for analysis was very short. I then opened Lightroom classic and opened Topaz Photo(Studio) option under Photo>Edit in>Topaz Photo(Studio) and the analysis was very quick. If I then made changes and it was “Previewing” and after several minutes I Force Quit the Topaz app. Some progress at least. Thanks
@james.whittle For the remaining crash you mentioned at the end of your post, can you confirm whether you’re using the same AI model that you previously loaded successfully? It can take up to 30 minutes. The model you’re using through Lightroom Classic’s Edit In workflow may be different from the one you’re invoking through the plugin, so it may need to go through that initial loading process as well.
Another possibility is a macOS disk permissions issue with Lightroom Classic, preventing the plugin from accessing the Topaz Photo models. Could you try these steps?
Make sure to apply these permissions to Adobe Lightroom Classic
If the issue continues, it could be something else happening in the plugin workflow by sending in your app logs to Support. You can find Logs in Topaz Photo > Help > Open Logs Folder. Send all the files to support@topazlabs.com so we can review what’s happening and involve the development team if issues remain!
Things seem to be working very well. I had the initial 16 minutes for the first image to be analyzed but no further issues with delays. I have had no other issues with “previewing” taking a long time . My only question is when in Lightroom Classic and I select Edit in ,my Topaz Choices are Topaz Denoise AI , Topaz Gigapixel (Studio), Topaz Gigapixel AI, Topaz Photo (Studio), Topaz Photo AI, Topaz Sharpen AI. I select Topaz Photo (Studio) and all works well. Do I need to remove the others and how to do so? The old version of Topaz Photo I was using was OK but I primarily did sharpening. This new version is phenomenal. Right now everything seems OK, thanks for your hard work. Jim Whittle
@james.whittle - Glad to hear that once the initial model unpacking was done, everything started working normally and processing speeds are back to normal!
For the lingering plugins, here’s how to clean them up on your M6 Mac:
Close all applications.
Open Finder > Applications and move any unused legacy Topaz apps to the Trash. From the list you shared, these would be Sharpen AI, DeNoise AI, Photo AI, and Gigapixel AI (the older apps with “AI” in their names).
In Finder, go to this folder: Macintosh HD/Library/Application Support/Adobe/Plug-Ins/CC
Look for the plugins belonging to those legacy Topaz apps and move them to the Trash. Make sure you leave the plugins for your current Topaz apps untouched.
As an extra cleanup step, you can also remove any remaining preference files associated with the legacy apps using this guide: How to Delete Your Plist Files.
Empty the Trash.
Restart your Mac.
This should remove the lingering legacy plugins from Adobe and free up quite a bit of disk space by uninstalling the older apps you no longer use!
(If in future or for an older computer you need to use the Legacy apps again, they will remain in your Legacy Apps Page and you can install them from there as needed)
