While installing a security update I accidentally installed Catalina. I do not have a Time Machine backup for my High Sierra 10.13. So now I have made a Time Machine backup in Catalina and my plan is to wipe the HD and re-install High Sierra. The thing is, is that some of my software will not work with Catalina and I really need them.
Now my question is, once delete everything from my Mac and reinstall High Sierra, what process can I use to bring back the files and apps since Time Machine won’t restore a backup from Catalina to High Sierra?
