Hi,
I understand now that I can’t open Photos on Time Machine Backup, The only reason I wanted to open it was to check inside to make sure it had backed up all of my Photos inside, Am I right in assuming theres no way of being certain that all my Photos have been backed up, I now realise I can’t use Time Machine Backup to randomly open Folders & Files ( thanks for pointing that out ), I am using:- macOS Sierra 10.12.6 ( iMac 22.5” 2017 ).
John.
