High Sierra Installer Download?

Clicking on your link works, be a little patient, as the page redirects you to

the App Store High Sierra download page. You must be using Safari to click on the link.

How do you explain that I can click on the link you provided and get through to the App Store

while using Safari, as does everyone else. I think you need to look at your system and see if you

are using any VPN software that could be blocking you or perhaps any AV software that might

interfere with your access to different sites.

Your next question seems to be directed to Apple, Apple is not here just users like yourself.

Many people think the way of downloading the Install apps for OS's like High Sierra, Mojave, Catalina

and Big Sur where the Installer app is downloaded directly to the Applications folder is preferable to

the downloads of Yosemite, El Capitan and Sierra, where there is a three stage process before you get to

the installer app. Even Apples instructions for this process are badly worded and catch a lot of people out.

Keep trying with Safari, as I say check if you are running any software that might interfere with the connection

to the App Store. You can quite clearly see that it works from my screenshot.

Working here as well…

Which Mac and version of macOS are you on?

Running Catalina and Safari Version 14.0.1 with Ad and Stuff Blocker. The link you provided works fine. Safari opens a Tab showing " redirect " and opens Apple Apps Store to the download.

If you haven't done so already, try restarting your Mac.

Can connect and download using Mac OS X El Capitan, macOS Sierra, macOS High Sierra and macOS Mojave.

Come on William the problem is at your end.
