where is the page with the Mac OS Catalina 10.15.7
As of today 10/11/2022, FINDER is absent on my iMac running Catalina 10.15.7
I have tried various fixes, spend half an hour this morning on the phone with an Apple tech and he couldn't fix it
I have external hard drives which I am on now, with a working Mojave 10.14.6 and thought that i could download the installer for Catalina 10.15.7 and reinstall it on the iMac internal hard drive or the backup hard drive to which I back up with Carbon Copy Cloner.
I did start up from be backup, which was operation correctly yesterday but it also shows an absent Finder
iMac, OS X 10.11
