Comment on Some basic info about USB

  The only devices that don’t have at least Thunderbolt 3 on all ports do use the Thunderbolt logo on the ones that support it, except the short-lived 12-inch MacBook (non-Pro, non-Air). Basically, for data transfer:

  • If it’s a 12-inch MacBook, the single USB-C port doesn’t support Thunderbolt, and only supports USB 3.1 Gen 1.
  • In all other devices, if the ports are unmarked, they all support Thunderbolt 3 or higher
  • If the ports are marked with Thunderbolt symbols, those ports support Thunderbolt but the unmarked ports on the same computer don’t.

  For power delivery, every USB-C port in every Apple laptop supports at least first generation USB-PD.

  For display, every USB-C port in every Apple laptop (and maybe even the desktops) supports DisplayPort alt mode.

  It’s annoying but not actually that hard to remember in the wild.

    I completely forgot the 12-inch one existed.

  Okay, the old ones that apparently have both do have the Thunderbolt symbol on the ones that are, though, so what’s the problem?
