Denoise AI on working

[Christopher_54]

Denoise AI suddenly stopped working on my M1 Studio running OS 15.3. Strangly, it seems to run ok on my M2 MacBook Pro also runnig OS 15.3. LrC version is 14.1.1 on both. Anyone experiencing somthing similar?

Define 'stopped working'. What happens if you try? Often it only seems that Denoise is not working, because the DNG does not appear where you would expect it. That can be caused by the sorting of the grid view, an active filter that filters out the DNG, or a smart collection that filters out the DNG.

Nothing happens at all when I press denoise. I expect to see the preview screen that allows me to increase or decrease the amount of denoising to apply. But this dialog just doesn't come up.

First, restart your computer. If the problem persists, try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.

Rebooting the computer fixed the issue. Thank you.

The dialog is likely hiding behind another window. This is pretty common and is fixed by changing the window mode and using the mac os tools to gather windows. You can also reset the preferences like @johnrellis suggests.
