I have made external USB (or SD) installers for MacOS for years, and they have been very useful to me. I made one for Mojave 10.14 when I first downloaded it. Now, I find that unlike in previous versions of MacOS, I can only download an updater, not a full installation of of the installer version 10.14.3. My machine is a "supported" one, not a "hackintosh." Is there a way to overcome this? Google has not helped. I found the Combo Updater to 10.14.3 on Apple's site, but it's not at all the same thing as a full installation.
