Apple Event: May 7th at 7 am PT
I currently run Mac OS 10.13.6 Sierra and want to make the jump to Mojave. Every Mojave download that I find is a supplement to the base version. Is the base version available anywhere for download?

I have this same problem. Thanks for your suggestion, but the reason we're asking is because those precise steps don't work. The upgrade to Mojave never completes.
I suspect we may need to upgrade to 10.14 before updating to the current version, 10.14.6, but cannot find the base file anywhere on Apple's site or in the App Store.
For anyone who gets this warning: “An error occurred while preparing the installation. Try running this application again,” consider trying the following:
Do a Spotlight search for "Install MacOS". It will find all the MacOS X installers on your hard drive(s).
Once you see it, "Install MacOS Mojave", scroll down to the Spotlight search results to the bottom to where it will read, "Open All in Finder". Select that, and a Finder window will appear with items grouped together.
Look for the grouping of Applications and you should find the installer. Select the installer, then either right-click and select "Move to Trash", or left-click and hold on the installer for Mojave and drag it to the Trash, located on the Dock at the bottom of the screen. If you are left-handed and have your mouse configured as such, reverse the left and right instruction from before. Empty the Trash.
When you click the link to return to the MacOS Mojave page on the Mac App Store, you'll note its button will have changed from "Open" to "Download". Download a clean copy (ideally with no other programs, especially web browsers, open), and the fresh, clean copy of the installer should launch and run without a hitch.
Hope this helps!
My MacOS Mojave install was performed on a Mac Pro mid-2010 tower.
I am also having trouble with Mojave. I have a Mac mini Late 2012 with 2.3 GHz Intel Core i7 and 16GB of RAM and the Intel HD Graphics 4000 running 10.13.6, which is not very stable sadly, and every time I try to download from the App Store by clicking the Open button on the macOS Mojave page I get this - This copy of the Install macOS Mojave application is damaged, and can‘t be used to install macOS.

thanks. the only one that comes up in the Spotlight search is High Sierra, which is what I have currently - 10.13.6.
maybe I'll just stay there. the iMovie update was the only thing that I was interested in, which won't work below 10.14 Mojave.
Boot into Safe Mode and try starting the upgrade from there.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing some system cache cleaning, volume verifying and directory repairing.
Here is what I found on Apple's support page: https://apps.apple.com/us/app/macos-mojave/id1398502828?ls=1&mt=12
"This copy of the Install macOS Mojave.app application is damaged, and can't be used to install macOS."
Problem is repeatable.
Direct link is https://apps.apple.com/us/app/macos-mojave/id1398502828
Try it without the last part of the link, this worked for me just now.
If Sierra is working I would tell you that Mojave could be a problem. I am having problems since installing it. Once you install Mojave there is no going back.
I am using macOS Sierra and I have an exact same question and I don't want to jump to Catalina either.
Please provide a solution/link which updates to macOS Mojave from Sierra.
Starting in Safe Mode allowed the Mojave installer to run. Problem solved.
thanks. that didn't work -
Your request produced an error.
