M1 Mac "Failed to scan system volumes" error

Current Behavior: If I leave PhotoStructure running for a few hours or more -not sure of the exact time frame unfortunately, I get the dreaded “failed to scan system volumes” error. Initial startup and processing works fine after some tinkering with other settings specified in the large library tune-up tips post, it’s only after leaving PS to work by itself for a while that it runs into trouble.

System: Mac OS Big Sur (11.4) on a 2020 M1 Mac Mini
Edition: PhotoStructure for Desktops (beta channel)
Version: 1.0.0-beta 9

Sorry for the bother, and thanks for the report!

I’m hoping beta.10 will address this for you: I parallelized the volume metadata fetching and added timeouts.
