Eh? I'm running the entire Adobe suite, including Lightroom and Photoshop, on MacOS 12—as well as several other current photographic post-processing applications.
OK, one last time. I am running Catalina. I cannot upgrade easily to a higher OS. Easily, I said, but, not worth my time and effort, especially since, as I was informed today, I will not be able to load anything beyond Monterrey on this computer, ever, so, really, why bother, since the computer will be ineffective in a year or two. I've been here, done it. You may be cruising fine right now with the old Trashcan, but, think of it as having cancer and it only has so long to live. I'm fine, it works great, I get plenty done as it is, but, shopping for a new one. No rush.
Now let me get out of there before that dawg chases me again. Bye.
