Hi - In section 4 on this web page, https://support.apple.com/en-us/HT208969, when I click on the link "Get macOS High Sierra", I get this error message: "This copy of the Install macOS High Sierra application is damaged, and can‘t be used to install macOS." Then how can I install High Sierra? I cannot otherwise find it in the App Store. Please advise how I can download High Sierra after all. Thank you in advance.
Hello, 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.
