Every time I click on the Download button, I get a tiny 22 MB install file in my Application directory.

Apple should have a way to download the full installer like they did with El Capitan and all reasonably recent versions before it. With 3rd part software there's no way to know if they haven't embedded some spyware or malware or whatever in their utility. And if this 3rd party utility does get the download from Apple then any Apple customer with Apple systems should be able to download it too. I'm holding out for an Apple-only solution. Sounds like Apple screwed up here.

It takes you to an Apple upgrade page that has a "Get MacOS High Sierra" link on it that takes you to the App store but if you click on the Download button, all you get is the 24.5 MB mini-installer file. And note that mini-installer file cannot be used with the createinstallmedia resource to create an installer on a USB flash drive. The complaint is that the mini-installer is not a valid installer application.

In my MacMini, there was a Sierra full installer, a Mojave full installer, and an El Capitan full installer present. I moved these out of the Application directory to another location and then tried to download High Sierra again but I still only get the 24.5 MB file.

In fact I have already downloaded the combo update for 10.13.6 (High Sierra, presumably the last update for that release of MacOS) from Apple Support. I did this on the assumption that the full installer download and upgrade might result in an earlier High Sierra version being installed and I would need to update it to the last/most recent level.

Having done this every time, including High Sierra (in September 2017), I can verify that it worked then too.

It seems to see Mojave and halt. Any idea how to get this older OS to install on this partition? My current boot options are the Mini's onboard drive, which is Mojave, or the other SSD partition, which is Catalina.

But I still can't download it on my Mac at work. I thought that perhaps our IT dept had set up something to disallow downloading of macOS so that folks wouldn't/couldn't reinstall over the "standard system" image. But they said that's not the case. Odd.

This article will discuss where to download and access installers for MacOS Sonoma 14, macOS Ventura 13, MacOS Monterey 12, macOS Big Sur 11, macOS Catalina, MacOS Mojave, MacOS High Sierra, macOS Sierra, Mac OS X El Capitan, OS X Yosemite, OS X Mavericks, Mac OS X Mountain Lion, Mac OS X Lion, Mac OS X Snow Leopard, Mac OS X Leopard, Mac OS X Tiger, and others too.

As you can see the App Store first searched my system and found that I already have macOS Mojave installer.app. Notice that it searches all locations, not just the Applications folder where the installer app normally is stored. It found the macOS Mojave Installer.app in a folder called test.

Software Update will search for the Installer and ask if you are sure you want to download the 6gb Mojave Installer. After clicking download you will get a new prompt for admin credentials to start the download (not to actually install yet). After the download completes you will finally have the latest macOS installer.app.

I was going to explain how to use installinstallmacos.py here but now realize the topic deserves a full article. I did not even get into hardware specific (Forked) builds. As you can see we have a lot to go over, so stay tuned. I will put the link here when complete.

One thing to note is that the installer that I get from the App Store is only 22MB initially, so I had to use the workaround of running the installer and then merging the data into the installer .app (How to Download a Full Size MacOS Mojave Installer ).
