When I try to download/open macOS High Sierra 10.13 from the Apple App Store I get an error message that this copy is damaged and cannot be installed. Where can I go to download this OS? I am currently running an older MacBook Pro (early 2011) with Sierra version 10.12.6.
MacBook Pro 13″, macOS 10.12
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 of a more recent version can be downloaded..
Don't use FireFox for this link…
