nsurlstoraged and CPU usage
Solution 1:
This solved the issue for me:
- Make sure you have a recent backup
- Quit Safari (if it is running)
- In Finder, type Shift-Cmd-G and enter
~/Library/Caches/com.apple.Safari - A Finder window will open, with the
com.apple.Safarifolder selected - Delete the whole folder
- Restart Safari
