Indeed, and what I am talking about happened after the Mac being released.
> By this point, in the late 1980s, the market was moving towards C++, and the beta version of Apple C++ compiler appeared in 1989, around the MacApp 2.0 release.[5] At the same time, Apple was deep in the effort to release System 7, which had a number of major new features. The decision was made to transition to an entirely new version of MacApp, 3.0, which would use C++ in place of Object Pascal. This move was subject to a long and heated debate between proponents of Object Pascal and C++ in the Usenet and other forums. Nevertheless, 3.0 managed to garner a reasonable following after its release in 1991, even though the developer suite, MPW, was growing outdated. Apple then downsized the entire developer tools group, leaving both MacApp and MPW understaffed.
