i'm still using el capitan and wanted to upgrade to mojave as i need some programs which don't run on the newest upgrade (e.g. myob). whenever i want to download mojave it comes up with: "This copy of the Install macOS Mojave.app application is damaged, and can‘t be used to install macOS."
is there anything that can be done? Thanks for any help and suggestion
MacBook Pro 13″, OS X 10.11
Are you using the Safari browser to click on the link, Firefox will not work.

That error message usually means that the App Store has detected a copy of Install macOS Mojave.app
in your Applications folder. Locate it, move it to the Trash, empty the Trash.
Connect your mac to your router via cable rather than rely on WiFi.
Restart your mac and go back to the App Store Mojave page, it should now say 'Get' or 'Download'.
Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading
and do not use any other devices that share the same internet connection.
If the App Store says ‘Open’ then it is detecting a previous download of the install app
go to the Applications folder locate Install macOS Mojave.app.
Move it to the Trash, empty the Trash.
Restart, click on the link again, the App Store should say ‘Get' or 'Download'.
thank you eau rouge, in the meantime i had spoken to apple support and he told me that i cannot upgrade from el capitan to mojave directly. i have to upgrade to high sierra first and from there to mojave.
i had read all of this before contacting apple. now i have updated to high sierra but it still won't let me continue to mojave. i click on the link and it asks me then to choose my application! if i choose iTunes it keeps telling me that it is not available in australia (where i'm based), when i choose AppStore it doesn't come up at all.
i might have to contact apple again...
Not true.
If you read section 1 in this link,
How to upgrade to macOS Mojave - Apple Support
you will see that the minimum OS requirement for upgrading to Mojave is
10.8 mountain Lion.
thank you so very much Eau Rouge - that was the problem as i was using firefox! all good now and in the final stages of updating :) have a wonderful day!
Yes, I should have said to use Safari and not Firefox in my first post.
updating from el capitan to mojave not working - anyone else has this problem?
