Photos Application
Hi, after installing Catalina my photos app failed to open. Each attempt to 'verify' & 'update' failed. I have tried to 'repair' as well but without success. While speaking with an Apple agent, he got me to uninstall photos library and install a fresh one from my external hard drive. Voila! all photos returned and the app worked. Sadly, upon the next reboot photos app was again not working. Any help to recover my 'lost' photos will be greatly appreciated. Many thanks
