MacPro (2019) Massive Performance problems after updating to MacOS Ventura across all Adobe Apps

 Time Machine only backs up data, not the operating system, so you probably didn't miss much relative to this issue. Even more sophisitcated back-up apps like Carbon Copy Cloner no longer back-up the OS because there are Apple protocols in place that prevent it.

Thank you very much for your words, Mark.

As I'm an Apple user since 1999 I really shoud have known better to not update without a prior TimeMachine backup so, at least at this point I must feel a bit stupid anyway. But I did it because the last time I can remember having trouble with a new MacOs in cambination with Adobe was with the step to Big Sur if I'm right... so some years ago.

The whole M1-thing I did not bear in mind, actually although here's a MacBook Pro M1Max next to me which saves my a** because of the situation. It's still on Monterey and works just fine. But some system critique alongside... calling a 2019 device “outdated” seems a bit problematic to me. But sure.. that's the zeitgeist.

No, I don't think you're stupid. There are all manner of complaints about application performance with Ventura. I'm interested in this topic because I am also on Monterey, and given that everything is working fine for me, on a 2022 Mac Studio Ultra, I am extremely reluctant to install Ventura, and this on a computer that is likely considerably more powerful than a 2019 Intel Mac. So I don't have a solution to the problem, but can suggest a possibility: quite apart from the question about whether a new operating system is ready for prime time and whether app developers are up to date with it, there comes a time when older computers and newer operating systems do not cohere properly and then one runs into these issues. Perhaps that is the issue you are running into. I would wonder also whether Adobe's major focus in its application upgrades is the newer Apple Silicon environment. I mention this because I believe that unless the hardware, the operating system and the applications are ALL well-matched to each other, perhaps one would encounter the kind of operational issues you describe. If you have no particular need for Ventura, perhaps you could get in touch with Apple and ask them how you could back-migrate to Monterey. It's quite a pain, but this may be your best solution for the time being. Personally, I won't upgrade unless there are major application featiures I really want and absolutely need Ventura, and even then I'll think twice. I think we've reached the point with the multiplicity of computing environments that the developers simply can't keep up with catering for every conceivable combination out there, and users are kind of left holding the bag when things don't cohere.

P.S.: My main question is ... When everything worked fine in Monterey, what has changed through the update to Ventura? Maybe it's just a checkbox in the preferences... maybe I'm just stupid
