As I have mentioned before I regularly listen to several podcasts. One of those I follow is Tech Stuff and I recently listened to their three-part episode on the Macintosh. These three aired on June 2, 7 and 9 of 2017 (Yeah, I am way behind on my listening). These comprise about 3 hours and 40 minutes of information on how the Apple Macintosh was conceived, how it developed and where it is today.
If you are interested in the Mac, you may want to download and listen to these three episodes.
