Big Sur with Current Photoshop

[David Eichler]

One of my Macs cannot use an OS later than Big Sur, which can't use the latest versions of Lightroom Classic, but can use the latest version of Photoshop/Camera Raw, with some limitations. What are some of the most common or important of those limitations (if any) for standard professional-level photo-editing? I don't normally use this particular computer for editing, but I am wondering how I would be limited if I had to. So far, I am just beginning to explore using the latest features in Lightroom Classic, but already I have found the AI noise reduction to be very useful, and I can see that Point Color will also be quite useful.

Which Mac can't use an OS later than Big Sur (which was awful)?

I didn't go through the list but there is Monterey after Big Sur and it is better.
