I would think that installing Catalina on top of an existing installation of Catalina shouldn’t be a problem as long as you use an installer for the same or newer version of Catalina as is currently on your Mac. This should be no different than doing an upgrade.
As with all upgrades, be sure to backup everything you don’t want to risk losing. Then download the installer and give it a try. - Brad - On Nov 26, 2020, at 19:55, 'Robert Cole' via MacVisionaries <macvisionaries@googlegroups.com> wrote: Dear List, Is it possible to reinstall Catalina, by running the installer and not loose my files? My Mac is sluggish and stops responding. I am so tired of hearing the word Busy, Its driving Me nutty! I am not ready for Big Sur yet, so hope that reinstalling Catalina will help. I did not want to do a new install by wiping the drive. Thanks, Rob -- The following information is important for all members of the Mac Visionaries list.
