The Mojave link in this article does not work. Via Safari it takes you to the App Store. When you start to download, the App Store tells you that the installer is damaged and cannot be used.

The link to the App Store to upgrade from High Sierra to Mojave does not work on my wife's MacBook Pro. When you start download, it stops, and indicates that the Mojave installer is damaged and will not work.

MacBook Pro 13″, OS X 10.11

When the App Store opens at the Mojave download page does it say Open,

it should say Get or Download.


The message means the App Store has detected a copy of the Install macOS Mojave.app

in your Applications folder. Locate it, move it to the Trash, empty the Trash.


Connect your mac to the router via cable.

Restart your mac, go back to the Mojave download page and try downloading it again.

Do not use the mac while it is downloading or any other devices that share the same internet connection.
