I have both a ProBook 4530s, and ProBook 4540s and have been using the hotpatch technique that this guide enables for quite a while.
And Skylake support was only introduced in 10.11 (.?), and only stable enough for use in 10.11.4 or later. Broadwell support in 10.10 is not stable (previous versions no Broadwell support).
Note: For Broadwell and Skylake hardware, you must install at least 10.11. The purpose of this guide is to provide a step-by-step guide to installing Mojave, High Sierra, Sierra, El Capitan, or Yosemite on the ProBook/EliteBook/Zbook equipped with Intel graphics.
