Don't forget that Apple was a heavy Pascal user in the 80s. Wirth designed Clascal (used with the Apple Lisa computer) for them, which then got morphed into Object Pascal for the Mac. Many applications were written in Object Pascal. Apple developed Lisa Toolkit (an application framework) for Clascal. This was then morphed into MacApp for Object Pascal.
