Earlier quoted context omitted.
Photos will never be a viable replacement for the full Aperture professional use cases -- they have different goals. Aperture might or might not run on HS (not sure), but holding to it until Photos catches up is not very good strategy, at some point it will just stop working (and it's not getting any new fixes, updates, etc). Better move to Lightroom or something similar.
> Better move to Lightroom or something similar. I don't want to rent software, and I don't want to install the dreaded Adobe installer. What other good alternatives are there? Darktable doesn't pass the test.
So, basically Lightroom.
