High Sierra Download

Tried to instal HS from the App Store but the download says the OS is damaged and I cannot instal it!

Any suggestions.

Thanks

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...


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


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