They were not. The early Mac operating system and Toolbox were written in assembly, with a Pascal API. MacApp was ported to C++ in the late 1980s and went C++ only in the very early 1990s, about 1991-2 with MacApp 3.
MacApp was the framework Apple wrote and promoted, but it wasn’t the primary API; lots of developers wrote directly for the Mac Toolbox or used any of a number of other frameworks like THINK Class Library.
