Windows has a Pictures folder. Before they started screwing with the OneDrive directories, it used to be in ONE location. Now it's in OneDrive\directory location, which works, even if it annoys me. The upside being automatic backup and restore. That Pictures folder is accessible systemwide and is accessible through EVERY application that can browse directories.

The Photos library on the Mac was not accessible via Lightroom Legacy. He (& I) could not locate it through the "Browse" functionality within the application. I think I could open the photos through finder, but could not import them through Lightroom Legacy. I could, however, Open With: from the Photos app, which then imports into the application just fine. This irked him enough to not want to do it, and I explained that it was the only way to do so, or otherwise export and import the desired photos in bulk.

I see what you're saying, but Apple's approach was clearly not intuitive for me, nor the Mac user. It's what it is, but Apple needs to facilitate working with their virtual folders/libraries natively through applications, not force users to resort to using workarounds... to export into interoperable formats for applications that run natively on their OS. Either Adobe is screwy or Apple is screwy here, but I'm leaning on Apple so far.
