I just noticed that you're using a Mac mini. If this is the 2018 model, then your computer uses an integrated GPU (Intel UHD Graphics 630) which has got access to around 1.5GB of shared system memory.  The system requirements for LrC 12.x are linked to below. Note the minium GPU memory is 2GB. I suspect this is the reason Denoise doesn't work on your system.

 

Worth noting for the future - always include your 'System Info'. This ensures that folk trying to help don't end up second guessing possi

@rodrigounda, do the menu command Help > System Info and copy/paste the entire output here, so we can see which hardware and versions of software LR thinks you're running.

"DirectX: NVIDIA Quadro P400 (31.0.15.3179)

Dedicated GPU memory used by Lightroom: 1949,5MB / 1980,4MB (98%)"

 

You've got a 6-year-old card with just shy of LR's required minimum 2 GB of GPU memory. Older cards with 2 GB of memory have lots of problems with Denoise reported here.

 

Your driver version, 531.79, isn't listed on Nvidia's Advanced Driver Search for that card:

 

https://www.nvidia.com/Download/Find.aspx?lang=en-us 

johnrellis_0-1683354799445.png

 

I suggest you install the most recent driver listed there (528.95):

https://www.nvidia.com/download/driverResults.aspx/204574/en-us/

 

Nvidia calls this a Production Branch driver, "designed and tested to provide long-term stability and availability.".  (There are no Studio drivers provided for this card.)

 

If LR still chokes on that latest driver, then I think it's unlikely that Denoise will ever work with your graphics card, and you'll have to upgrade. It appears that the graphics manufacturers don't pay much attention to driver problems with their older hardware.

"Funny thing it was working 2 days ago."

 

Perhaps your graphics driver got auto-updated to the currently installed version, 531.79.  I now see that 531.79 is what Nvidia calls a Game Ready driver, which are tested for games, not creative apps, and which tend not to be as stable.  Since 531.79 isn't even listed for your card, it may not be compatible at all.

Above usually occurs when the GPU test failed when LrC launched. You'll need to follow the steps provided below to reset same. However, given that the VRAM on your card is less than the minimum 2GB I suspect the test will fail again at some point. You'll also need to check whether the driver is up to date as described above.

 

  1. Quit Lightroom Classic.

  2. Locate the Camera Raw GPU Config.txt file.

    • (macOS) /Users/[user name]/Library/Application Support/Adobe/CameraRaw/GPU/Adobe Photoshop Lightroom Classic/Camera Raw GPU Config.txt
    • (Windows) \Users\[user name]\AppData\Roaming\Adobe\CameraRaw\GPU\Adobe Photoshop Lightroom Classic\Camera Raw GPU Config.txt

    The user Library folder is hidden by default in macOS X 10.7 and later releases. Use the directions here.

  3. Manually delete the Camera Raw GPU Config.txt file.

  4. Relaunch Lightroom Classic.

Hi, I am also getting the same "Denoise was not applied" error with my new machine (Mac Studio). Not sure if there was a solution to this yet? It was working just fine and denoising within seconds, but then stopped working. Thanks.

@Keyvantmwrote, "I am also getting the same "Denoise was not applied" error".

 

That's a different error than what some others have reported here. Please post a screenshot (not a phone pic) of the full error message.

 

You're on Mac OS 12.4, which is a year old. On Mac, the only way to get updated graphics drivers is to update to the latest version of Mac OS (13.3.1). LR's AI commands are very sensitive to bugs in graphics drivers (of which there are many, which is why the manufacturers frequently release updates).

@Keyvantm, to build on Ian's reply, by sharing one of the problem files, we can see if the issue is with the file itself or your configuration.

 

You've got an Apple Silicon M1 Max with 65 GB running Mac OS 13.3.1, so your computer is fully capable of running Denoise.  The error message "There was an error writing the file" is curious:

suggesting that the issue is not producing the denoised DNG but rather writing it to disk.  (Hard to know since LR's error messages can be less than informative about the underlying cause and sometimes just wrong.) A couple more troubleshooting steps:

 

1. Ensure LR is granted Full Disk Access (not Files And Folders) permission:
https://community.adobe.com/t5/lightroom-classic-discussions/quick-tips-how-to-give-full-disk-access...

 

Without Full Disk Access, LR can do all sorts of screwy things. Let us know whether that fixes the problem.

 

2. Try putting a copy of that .cr3 on your Desktop and importing it from there with the Add option (so that it stays on the Desktop in your catalog). Verify that the imported copy is still on the Desktop by right-clicking it in the LR catalog and doing Show In Finder.

 

Then do Denoise on that copy.  That should cause the DNG to be written to the Desktop.  Does that work?

Thank you so much John and Ian. I think the issue was indeed caused by access to (external) drive and now seems to be resolved and working just fine. Thanks again for looking into it!

@Vladimir23773166z0w9, please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

 

Click the Apple icon in the upper-left corner and do About This Mac. Post a full-resolution screenshot (not a phone pic) of the About window.

I have a Mac Mini 2018 (my specs listed below).
I initially had the same error, but I noticed that I received it when I started the process and went ahead opening Chrome. However, even with Chrome closed after, I kept getting the error. I simply Quit LrC, allowed back up, reopen LrC and proceeded to try again. This time I ensured not to open any other software. Just allowed it to continue. Denoise was set to 50%. Estimated was 6mins, but I think it finished much faster.

I ended up buying an eGPU to get rid of those pesky errors (and enable some 3D gaming as a bonus). Works like a charm now.

I have the exact same problem. I have a Sony A7 (1st gen), and I get an error on all my ARW images. I have a 16" MacBook Pro with AMD Radeon Pro 5500M with 4GB of GPU RAM. Intel Core-i9 8-Core, 2.3GHz, 16GB RAM running Lightroom Classic. All software (Lighroom, Creative Cloud and MacOS 13.4 up to date). 

 

I am a long-time Lightroom Classic user and this issue is very dissapointing (and frustrating).

 

I am about to try Rikk Flohr's suggestion of uninstalling LrC and it's preferences. I'll report back later.

I have finally solved my Denoise AI problem. Firstly, resetting Lightroom preferences or re-installing Lightroom does not fix the issue, at least for me.. it seems related to Intel Turbo Boost. I installed a free tool called Turbo Boost Switcher that sits in the MacOS menu bar, which allows you to disable Turbo. Doing so, and waiting for the CPU temperature to cool and fall under 80'C, Lightroom's Denoise worked a charm. I've gone back and tried dozens of photos that failed and all of them now work !! 

 

Give it a try, I hope it give you some level of success.

Strange, I just checked Denoise on a  2019 MacBook Pro with exactly the specs that you mention above. It was using LrC 12.4 I ran Denoise 5 times with Sony A7 MkIII files and repeated with 5 much more onerous Canon EOS R5 files. I monitored CPU, GPU temperatures and useage during each test, and on each occcasion the turbo CPU cores were barely active, likewise the main CPU cores. Denoise mainly uses the GPU.  Even so, the maxium CPU and GPU temperatures never exceeded 80 deg C

 

As a further check, I batch denoised the 5 Sony and 5 Canon files (i.e. 10 files in a single batch) with the same results as above.

The later models of Intel Macbook Pros are notorious for overheating due to clogged fan vents.  Use the free Intel Power Gadget to see if the CPU temperature is approaching 100C. If it is, then try cleaning the vents yourself or take it to a certified repair.

 

A correctly operating Macbook Pro will never overheat.
