Ten years ago I paid for some proprietary software to help me collate my photographic archive. The project was very successful but the software is also 32bit Intel only. Since Catalina onwards I have not been able to access the archive at all. It causes me a lot of anxiety.
Thanks Adobe / Apple! Hopefully Lightroom 6 runs on Windows, but I just never seem to have gotten around to trying. I think it’s mostly out of fear that it won’t work and I will realize I am shut out of my collection metadata forever.
