If you get a corrupted message...

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


If you’re short of bandwidth or data… 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.

Troubleshooting macOS Install:

Contact Apple Support:

If you cannot access this service, then contact Apple Support.

Apple Contact Info:

  • Contact Us - Choose Locations
  • Proceed from there, as necessary
  • Why the Wait: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)


Screensharing with the Apple Rep:

To troubleshoot this over the phone with the Apple Rep screenshare the camera of your iPhone and/or that of your Mac. Ask a friend, or family member if you may use their phone, if you do not have one handy.
