You can revert from another backup— it doesn't have to be Time Machine.

A boot clone for example.

If you have no backup, you'll have to revert by wiping the hard drive and you'll lose all your data. A backup of your own documents should be fine. Then boot into Recovery Mode and choose erase and install using Shift-Option-⌘-R.

How to reinstall macOS from macOS Recovery - Apple Support

This will reinstall the original OS that shipped with your Mac and you'll need to upgrade from there. After that you can move your own documents back, which should be unaffected by the Catalina upgrade.

I don't have a back-up from yhe OS but just from documents.

Apple is becoming a very sour apple for me for I work with ADOBE Acrobat Pro and Dreamweaver every day and the programmes costed a lot.

I was definitely in favour of Apple, have an iPhone, a MacBook Pro and my my iMac, but what Apple has done now must be repaired by themselves!!!

Thanks for the replies. For me it is too late to respond correctly and completely. An hour ago I started t copy large parts from my iMac to my Time capsule: a map 2017, pictures, applications, crative cloud files and downloads. This will take 8 hours tonight. A map “mappes” appeared to be too large for Time capsule. What to do with that?Tomorrow I have in mind to copy also: webpages, public, music, my albums,films, and maybe also the map dropbox???

Hopefully I do well and understand it well??

Im 77 years old, had a stroke about a month ago and my english and technical understanding is far from perfect. I will continue to sleep now and I hope that tomorrow things will come further.

thank you very much so far.
