Yes and no. There are so many dofferent parts to an operatong system that you quickly favor the text console because its so easy to do. If you are going to work on a GUI first thing, you might as well forgo the operating system bit and just write it as a program in some other OS while you perfect it
MacOS Classic was GUI first. There was no terminal; the closest thing that came to a console was the MacBugs debugging interface to inspect the assembly instructions.
