macOS Catalina download problem
My mac has currently the mac OS Mojave 10.14. I downloaded the mac OS Catalina from the APP store. But when I click the Install button, an error message appears :an error occurred. Try later:. When try again, I had to download the OS again, but during installation, same error message appears. Any suggestions how to successfully install the Catalina OS?
