Apple Intelligence is now available on iPhone, iPad, and Mac!
Hi, I am trying to upgrade from High Sierra 10.13.6 to Mojave 10.14. When I follow the link to the Mojave update in the App store I get the following error message
This copy of the Install macOS Mojave application is damaged, and can‘t be used to install macOS.
Can anyone help please? Thank you :)

Hi, thank you for your help. This hasn't worked, I've repeated the steps several times and I still get the same error message when I try to install the OS. What else should I try please? Thank you.
Thank you :)
You're welcome.
