Can't download High Sierra full installer.

Help. I'm currently running High Sierra, but I keep getting network related errors. Apple Support wants me to reinstall High Sierra to fix the errors. When I go to app store, High Sierra page, and hit "download", I get the error:


"macOS High Sierra failed to download / Use the Purchased page to try again."


Well, High Sierra isn't on my purchased page.

How do I get around this?


Thanks

That is not how you get High Sierra in 2023. Using Safari only, select High Sierra from its link in How to download and install macOS - Apple Support and that will open a panel on the Mac App Store from which you download the full High Sierra 10.13.6 installer application into your /Applications folder. Cancel if it wants to proceed with the installation.


If you have a spare 8GB USB stick, you can also make a bootable installer from the High Sierra installer app following the instructions at Create a bootable installer for macOS - Apple Support


Here is an example in the Terminal of how I created a bootable USB installer for Sierra. Just change the installer name to High Sierra with the appropriate escapes (\) for white-space.

Also, I don't see this mentioned in the thread, but have you tried to reinstall the High Sierra app by booting into Recovery? (Option-Command-R)
Reinstall macOS - Apple Support

Forget that method. As I've been telling you it won't work. The Recovery method of installing HS is gone.

Can you elaborate on this, please?

Is it deprecated or just broken?
