Most of my usable applications became non-usable after installing OS 10.15. I presumed they all wanted me to go to their cloud processing so annual charges could be made.
That is an accurate assessment. Don’t forget that this is a conscious decision made by these app developers in 2007. That was the year they decided to move people to a subscription or cloud-based product. How much money have you spent on software since 2007? Were did you spend it? Let that decision drive your purchases going forward.
I had a devil of a time going back to 10.14. Even the Apple recovery system interfered. Finally had to erase the whole disc of OS 10.15, install 10.14 from another computer, and install my ** data from my backup drive.
That is exactly the correct way to do it!
Question is: How can one upgrade to 10.15 w/o losing access to data created with non-cloud applications?
You have a few options:
1) Stay on 10.14. In all honesty, don’t expect 10.15 to be stable for months. I generally don’t upgrade until after Apple announces the next version in June and essentially stops working on the old version. But given the massive changes in Catalina, I might just use it only for testing until 10.16 is stable.
2) Replace your old apps. Now that you have restored 10.14 and your old apps, you can plan for the future. Archive your existing documents and data into a format that is more portable. Then look for replacements. Not all developers are moving to cloud-based apps.
3) Run old apps in a VM. You can have your cake and eat it too. Upgrade your Mac to 10.15 and then install a 10.14 VM for running those old apps. It is a little clunky, but it works. Look at the bright side, that is essentially what Apple is doing with iPad apps in 10.15.
