I'm trying to update my operating system from Sierra to High Sierra. At the Mac App Store, when I clicked on the link to upgrade to that version, I got a message stating that that link was damaged and could not be used. Can anyone help me? I can't find any other link. Thanks!
Ah, so much for Apple's error codes...
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 can be downloaded.
Thank you! I was able to reach Apple Chat and he suggested the second option which worked. Thanks so much for your help, too!
Good work, take care my friend. :)
