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, restart, then a new copy can be downloaded


Try reinstalling this in Safe Mode, but not using Firefox...

Safe Boot, (holding Shift key down at startup).
