Since I updated to macOS 15.0.1 I have a problem with MetaImage: After (!) editing a file from my Pixel 7 phone (jpg + dng) MetaImage can’t no longer read and preview any image files. Instead of thumbnails I see spinning wheels. Because of that, also selecting images for editing doesn’t work. The app does not hang, operations not linked to image files, like quitting, work normally.
Restart of MetaImage doesn’t help, but restart of macOS does. Nevertheless, quicklook in Finder works totally normal with these files from the Pixel 7 device (and others).
I have experienced this now a couple of times, unfortunately, trying to trigger the problem directly after reboot did not work. There must be some additional condition.
Update: The problem is an extremely slow preview of files from my Pixel 7. If I wait long enough – several minutes –, it then functions normally until I select another image.
Logging out and back in resolves the situation (no reboot required).
