Catalina will not install from USB
I had Catalina running fine on this 2013 MacBook pro until a MacOS Update tried to install to only tell me that it could not install on my Macbook. Back to square one. Trying MacOS from the internet installed MacOs Lion....which when installed does work, but I need Catalina which was working just fine. So a nice new copy of "Install macOS Catalina" was put on my new Sandisk USB stick, plugged into the USB port to boot.......and the progress bar goes all the way to the end and hangs....never completing. No shortage of space on the 750g SSD which is empty. Anyone have a clue about why I have this failure?
