Post https://support.apple.com/en-us/HT209594 warns that Apple Aperture will not work in the next release after MacOS Mojave, for technical reasons. There is advice on how to migrate your Aperture Library to Photos, or to Lightroom Classic, but not to Luminar or Capture One Pro. I guess ApertureExporter would be helpful, though I have not yet tried using it. I believe there is an Aperture importer tool in Capture One; has anyone any experience with this?
I’ve been putting some metadata in filenames, eg film stock, film camera used etc, so I’m currently undertaking the rather massive task of transferring this metadata to keywords. (I’ll try doing the same for albums.) However, in the process I’ve had warnings that some files are not available at full resolution. I’m presuming these might be from my experiments with referenced files, rather than those in the Aperture Library (the vast majority). Can anyone confirm this? Is there a way to get referenced files into the Aperture Library (or even find out which projects are referenced)?
