    Didn’t some early 2000s Mac USB cables have a bit sticking out and a notch on the computer so they could only be used with Macs?

      Compliance reasons. USB spec at the time didn’t really allow for extension cables because it added an unknown amount of resistance.

      The notch was a workaround; they were within spec for the intended device both with and without that cable.
