Microsoft says the updated word and ppt. can only be used on Mac that are 11 or above.
Microsoft's policy these days is to only support the three most recent versions of macOS. Right now, those are Big Sur, Monterey, and Ventura. When Sonoma comes out, Big Sur will fall off the list.
I bought my macbook in 2012 and it is still working fine. Can I go back to the previous system so I can use word and ppt. and get my desktop info back?
Yes, you can go back – but you'll have to either do a full restore from a backup, or do a "clean install" (where you erase the volume on which you are going to install the older OS). That's because you can't install an older OS "in place" over top of a newer one.
If you do a clean install, you'll want to back up your current system to a spare drive first (a good idea, anyway) … then start up from a drive other than the one you want to do the installation on. (Say, start up from the backup.) After you do the clean install, you can go about manually reinstalling applications and data (and entering "license keys" and such).
