Latest PM6 Color Management broken
« on: March 31, 2025, 12:30:03 AM »
On macOS 15.3.2 color management in the latest (last) version of Photo Mechanic 6, build 7269 thumbnails and previews look flat. This is for JPEG images with embedded sRGB and Adobe RGB (1998) profiles.

Reverted to Photo Mechanic 6 build R7212 and colour is accurate.

I compared the images with Lightroom and Photoshop, both Adobe apps show/read the color profiles correctly.

Please try deleting your cache folder.

1. Quit Photo Mechanic and open a Finder window.
2. Click on the 'Go' menu at the top of your screen.
3. Hold down the 'Option' key and a 'Library' folder will appear in the menu. Click on that to open the User's Library folder.
4. In the 'Library' folder, find the 'Caches' folder and in that folder find the 'PhotoMechanic' folder and delete it.
5. Then, launch Photo Mechanic 6 and see if the problem persists.

Thanks I followed your steps several times and the issue remained.

A workaround is in Settings, I set the "Default ICC profile if undetermined:" to "No default profile", so all the good!

FWIW for decades I've had it set to "sRGB" to show embedded JPEGs in raw files accurately, and this still works in Photo Mechanic 6 build R7212.

In Photo Mechanic 6, build 7269 it doesn't - unless you view at 100%. Deleting the cache between launches fixes it for a while.
