Downloading and Installing Mojave
I'm on a 2017 MacBook Pro running Sierra. I want to upgrade to Mojave, can't go any further with the software I need to run. Anyway when I try to download Mojave from the Mac App store it gives an alert saying that "This copy of the Install macOS Mojave.app application is damaged, and can't be used to install macOS." Anybody know why I can't download it? Is there another source to download Mojave?
