People always say this but there is no real relationship there. When hardware vendors add security technologies to the hardware, the major third party operating systems add support to use it pretty much immediately, and in many cases before the hardware even ships because the hardware vendor publishes the documentation ahead of time.

Try to name something where Apple was the first to support something (by a non-trivial amount of time) not because they were the first to add hardware support but because they released the combination of hardware and software in the time between when e.g. Intel or Qualcomm added hardware support and when Linux or Windows added software support to use it.
