Question

AI Denoise is Not Working with my M1 Ultra Mac Studio, Regardless of File Type

  • August 19, 2025

I am currrently using an M1 Ultra Mac Studio with Lightroom version 8.5 and macOS Sequoia 15.6.  

I am unable to get AI Denoise to work with any file type (DNG, NEF, RAW, etc.). 

I've tried uninstalling/reinstalling Lightroom. Made sure I was using the latest version. Checked to make sure all the file types I was using were supported, but the problem still persists. 

When I try to click on the "Denoise" box, it brings the screen up with the progress bar, and looks like it's running without issue. But after about 2-3 second of running, it just cuts out and does not progress any further (progress bar/box disapears and goes right back to the normal edit screen).  Then when I try to click the "Denoise" box again, it won't even bring up the progress bar screen. 

Other AI/generative functions are working without issue. It's just the Denoise. 

Any guidance/help troubleshooting/resolving the problem would be greatly appreciated. 

Thank you.

    Hey, @helpful_genius0046. Welcome to the Lightroom Community. I'll need more information to help you figure this out. Please share the system information from Lightroom under Help > System info > Copy and paste into a text document > Upload and attach here. 

     

    Are any of the images synced from Lightroom Classic? In Lightroom, open any image & check the 'i' Info panel to find the current sync status. 

     

     

    Let me know how it goes. Thanks!
