When it’s time to install a new version of macOS or download a new update, nearly everyone turns to the Mac App Store to start the process. While the App Store makes OS installations easy. An old installer image is also incredibly handy if you’re reliant on 32-bit apps and haven’t updated to macOS Catalina yet. As we’ve covered previously, you can actually set up a Mac virtual machine using a virtualization app like VirtualBox.

Most of the time, you can re-download the current version of macOS via the Mac App Store, and older ones via these links:
However, I’ve run into a situation several times where the Software Update mechanism simply refuses to initiate a download:
Thankfully, macOS installers can be downloaded via Terminal in macOS Catalina. This command will download the most recent version of macOS, depositing it in your Applications folder:
softwareupdate --fetch-full-installer
The softwareupdate command has some neat tricks up its sleeve, as pointed out by Armin Briegel:
The --fetch-full-installer flag has a sub-flag: --full-installer-version which allows you to download a specific version.

During my testing in the Catalina beta version I was able to download 10.15, 10.14.6, 10.14.5, and 10.13.6. I was not able to test if 10.13.6 would download the hardware specific build of 10.13.6 for the 2018 MacBook Pro, since I do not have that hardware.

So, to pull 10.13.6 down, you’d use:

softwareupdate --fetch-full-installer --full-installer-version 10.13.6
I wish Apple would just have a support document up with direct downloads for all of this stuff, but this tool is not a bad alternative.
