How does one restore default user account login icons?
Howdy - I seem to have lost the ability to select default icons for account logins. I have located the User Pictures folder with the .tif files on my mac (Macintosh HD ->Library-> User Pictures, and confirmed the files exist. I am unclear as to why they do not load under default selections when working within the Users & Groups of System Preferences. Instead, I see "No Items". Is there a simple way to restore them?
Thanks
