App icons not showing in Time Machine backup
The icons of all my applications have suddenly stopped displaying in my Time Machine backup. The applications themselves seem to have been backed up - judging from the size of the files - but instead of the icon there's now a default Apple icon (indicating that the file is missing – see attached screenshot).
The app icons on my MacBook are displaying fine.
Does anyone know what to do about this?
