Mojave

I am trying to upgrade to macOS Mojave but comes back with the error "This copy of the Install macOs Mojave application is damaged and can't be used to install macOS." I am using 13" Macbook Pro mid 2012 and currently have macOs High Sierra Version 10.13.6 installed. How can i fix this problem?

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 High Sierra App in Applications, so expired Certificates are not expired.


Or... trash the Install MacsOS High Sierra.app in Applications then a new copy more recent version can be downloaded.
