Upgrading a Mac:

For reference...

Determining which Update(s) will Install:

I. Verify Compatibility:

A. Start Here: Learn About Compatibility and how to Identify your Specific Mac Model - Apple Support

B. How to Verify:

II. Reveal your Model:

What is the Model of your Mac? To find out...

1. Go to: Apple menu
2. Click: About this Mac
3. View: Second Line-Down

then...

II. Compare the Results:

See if the Model you found is shown here:

• macOS Monterey is Compatible with these Computers - Apple Support
• macOS Big Sur 11 Hardware Requirements - Apple Support
• macOS Catalina 10.15 - Hardware Requirements - Apple Support
• macOS Mojave 10.14 - Hardware Requirements - Apple Support
• macOS High Sierra 10.13 - Hardware Requirements - Apple Support
• macOS Sierra 10.12 - Hardware Requirements - Apple Support

III. If Compatible:

• Back Up your Mac First:  Be certain you Create a Time Machine Backup of your Mac, so that way you can have something to restore your Mac from, should anything go wrong with the reconfiguration.

Do you get the certificate error as well? The certificate is registered to a dns name that is different from the server that tries to use it.

The certificate says "images.apple.com", and the server that seems to send it is "updates-http.cdn-apple.com".

So it seems to be some issue between us and the webserver. But I will not be installing any images from this page until they fix it. I would like to report it somehow, but there seems to be no way to report such issues on their pages. But I'm pretty new here, so maybe someone else have some suggestion on how to report this issue?

I don't know about iron1965, but I see a page about OSX Sierra, and that I should log in to Mac App Store to download and install it. But its not available in the store when I search for it.

But I know I had Catalina running on this Mac before I wiped it. Now El Capitan is the latest available in the "bought" section. And that image puts the Mac in an endless loop of "no eligible packages to install" and reboots. I need to get past El Capitan, and from what I understand, Sierra is a necessary stepping stone because of some filesystem upgrades or something. But as long as this certificate error is present, I am uncomfortable downloading and installing the necessary images.

What exactly happens when you try...

Yes, it should direct you to the AppStore, some have had trouble getting there using FireFox, do you not see this?

Background is 1st link, allowing Appstore is what happens if you view in AppStore...
