I run Photolab 9.2 on latest MacOS. since at least a month I cannot run a database backup in Photolab. Every time I do (menu File–Project Database–Create a backup) Photolab crashes with the error message “Attempt to access an object not found in Store”. Once this error show, and I click the Close button on it, the app freezes. The saved backup is tiny in size, so likely an empty file.
Now backups are important. Especially since I use keywords and Projects in Photolab.
Now, that you’ve already used PL to add keywords etc. I propose to create a time machine backup and to check if all images you worked on have either .xmp or .dop sidecars or both.
If you have the TM backup and sidecars, download the installer again and re-install it. Occasionally, you need to trash all the files that are created when PhotoLab is used (except for the license file(s) that I always keep).
I use “Find Any File” or “EasyFind” and search for terms like
begins with com.dxo
begins with dxo
contains photolab
The first two searches help to assess the situation while the search for photolab is more specific. PhotoLab 9 entries come as photolab9, photolab 9 and photolab v9 respectively - and unless the system is set to be case-sensitive, upper- and lowercase letters are treated as same. Experienced fans of the CLI can use the “find” command instead of using a graphical wrapper (e.g. EasyFind) as I do.
MacOS’s Spotlight can be used too, but it does not access all folders in order to protect the user from deleting vital parts of the OS.
