I have a Catalina mac which is not compatible with the latest Macosx. Do I have to erase Macintosh HD to clean install Catalina or will it suffice to reinstall the Catalina from USB pendrive??
I have a Catalina on mac which is not compatible with the latest Macosx. Do I have to erase Macintosh HD to clean-install Catalina or will it suffice to reinstall the Catalina from USB pendrive??
Is there any other, simpler method to install Catalina from scratch on the Mac? I simply want to install it anew without applications and settings in order to make it work faster and without errors which have accumulated for years.
Mac mini, macOS 10.15
