I accidentally clicked the upgrade message, thinking I was upgrading something else, which downloaded Mojave.
I was then presented with a window to install Mojave. I don't want to install Mojave. It appeared I could not close the window, only minimize it. But once I did minimize it I was able to right-click and select Quit.
I would like to completely remove whatever was downloaded because I'm afraid it will install without my consent. Any solutions to remove the download?
