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managed to garner a reasonable following after its release in 1991, even though the developer suite, MPW, was growing outdated.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.

And then most just moved into Codewarrior and PowerPlant anyway.
