Most Apple podcasts react to this week’s news; this one tells one story per episode, at length — episode 0 spends 94 minutes on the company’s 1970s origins, and the current five-parter walks minute-by-minute through the death of classic Mac OS, ending with episode 6, “Apple’s Mac OS Crisis: Copland (Part 2).” Seven episodes are out, all free to stream, with membership adding early access and ad-free listening.
