Cannot install MacOS Mojave using the App Store Link in this article

As the Author of this thread, you may need to delete the failed download

and try anew; perhaps try Safe mode startup, to see if there is some glitch?

• Use Safe mode to isolate issues with your Mac - Apple Support

As part of troubleshooting you may also consider using macOS Recovery

& look into tools within that separate startup system to check/repair HDD.

Was the link within the macOS Mojave page online and hidden

so you had to click on other words to get it?

I see one within here:

Upgrade to macOS Mojave - Official Apple Support

https://support.apple.com/macos/mojave

And within that Get macOS Mojave from the App Store>

https://itunes.apple.com/us/app/macos-mojave/id1398502828?mt=12

Or was yours from a different link?

There were more than one; some are depreciated or only go to Catalina now.

Good luck & happy trails!🌞🌻

The link works fine for me, but I have no need to get mojave macOS10.14.6.

Had you tried starting up in Safe mode and see if that helps sort it out?

(from there it starts installing the Installer available in Launchpad/Applications to continue; I quit it.)

Try this. Go to the Applications Folder. See if "Install macOS Mojave.app" is there. If it is drag it to the Trash. Enter your administrative password to trash it. Download a fresh copy of the macOS Mojave installer.

The .app file isn't in my download folder.

The Mojave installer should be in your Applications Folder, not the Download Folder.
