What to Do:

Catalina Install Usb

You need to use Safari for this. Firefox will not work. So, what to do...

Before the clean installation of macOS 10.15 Catalina it’s recommended that you first delete junk and dusty files from the current macOS. There are many free and paid tools to clean junk but the quickest option is to run CleanMyMac X. Macrumors 68040. Create a new partition for Catalina (use a new disk or shrink the Mojave partition), then after Catalina is installed, use Migration Assistant to get your files, apps, and settings from Mojave.
