Let’s just say yes up front.
If you’re a Mac user, now or at any point, you probably remember the models you used with great, perhaps alarming, clarity. Perhaps the first one was at school, or a friend’s house. Most likely not the office, but there are exceptions. You may have vivid memories of some aspects of the then-current OS: some version of 7 or 8, or, if you’re on that side of thirty, maybe Jaguar or Panther. Maybe even iOS. Maybe you remember beige Macs; maybe bondi. Maybe all you know is aluminum and white polycarbonate.
