That is because it's an Upgrade, Updates would be like 10.13.5 to 10.13.6, upgrades would be like 10.13.x to 10.14.x or 10.15.x, etc.


Don't use FireFox or WaterFox for this link. it'll mess it up...

If you get a corrupted message...

Naw, not damaged, it's just that you have an old copy already in Applications, there are 2 cures...


Disconnect from the Internet & set the Date back to 2014, then you can run the Install MacsOS Mohave App in Applications, so expired Certificates are not expired.


Or... trash the Install MacsOS Mojave.app in Applications then a new copy can be downloaded.
