I updated to Sequoia 15.8 a few days ago and I am experiencing the bug discussed below. QuickLook for raw images (NEF, in my case) does not work. Relaunching the Finder briefly helps. Unmounting my camera cards after importing NEF images fails requiring a Force Eject.
Fortunately, Adobe Lightroom seems to work so I can still import and edit images.
I can wait for Apple to fix this or go the nuclear option and downgrade to 15.7.9. ![]()
Edit to Add: Have filed a bug report with Apple.
