I want to upgrade to Mojave but there is no room on my main disk drive to download it. Is it possible to download it to a usb drive and then upgrade the operating system on main disk drive from there?


It is easier if you free space on your main drive, move the stuff to iCloud, Google drive or USB.

You would have to free some space anyway.
