That’s a really strange hill to die on. I know I learnt Pascal as a teenager on a Mac Plus. It had several third party development environments and there was a thriving shareware/freeware scene, developer tools were there. In the end what harmed the Mac was that it was much more expensive than PC clones.
Even when a BASIC implementation was built in, getting a better one from third parties was very common on all platforms. You can look at magazines from the time if you don’t believe it. The Mac was by design more of an appliance than the Apple ][, but it was not the black box some people here seem to think it was. This whole thread is full of assertions that are demonstrably false in about 10s worth of Google search.
