which user's perspective? i mean, are you speaking for yourself, or are you endeavoring to speak for everyone?Ideologically, yes it is progress, but from the user perspective is a regression as an app that worked in say 10.14 won't work in 10.15. Maintaining 32bit compatibility is costly as it needs at least some work.
Yes I use Darktable on Ubuntu instead of Lightroom that is a progress![]()
it is up to the app developer to keep up with new OSes, not apple's job to hold back their tech to accomodate older apps. hence, the developer betas, etc.
