I chose a large image by mistake and now that part of System Preferences is trying to load images endlessly. I need to know how to stop the process.
Nothing loads so you can't stop it and can't access any other preferences.
Things I've tried that on't work:
- Force quit: it quits but same problem when you open System Preferences to try again.
- Chose a tiny image to replace the large one, by option-clicking on that image.
