macOS High sierra
I am trying to download a copy of high sierra. I have seen the replies that have a link that redirects to the app store. When I get there the button says open. When I click on open it tells me the install file is damaged. I am not sure if there is a damaged version on my macbook that I am unaware of. I just need to download and install high sierra so I can upgrade to newer OS.
MacBook Pro 13", macOS 10.12
