I managed to download FAF on the second try without any restrictive warnings. It found 16 items of which I've been able to delete 7. The following 9 won't delete or move to trash. A message appears as follows. 'There was an error (code -5000): Permission denied. Try "Move to Trash" or using "Find All" instead' and this message also ' “AdobeHeitiStd-Regular.fontinfo” can’t be modified or deleted because it’s required by macOS'. Any further advice appreciated.
