[macOS] Emulation speed and CPU usage - benchmarks

So, I've been comparing versions and builds, with various toolchains and Qt versions too.
Tests were done on macOS 10.14 on a 6-core i7-8850H with 16 GB of RAM... results are _odd_.

I'm running releases builds with the following settings: unthrottled speed, no frame-skipping, 2 docks only (LCD and settings) at minimum window size (ROM: 83PCE 5.3.1 / 5.3.1.)
For emulation speed % and wait a few seconds to average the value after the calculator has finished booting (home screen, blinking cursor).

_Note: I'm writing "v1.2-dev" as 6c7b5e0 right now, which is the current master._

What the hell happened with the 10.14 SDK... ?
