That is OSX.. lets see the 'activity monitor' and a double click on the "CPU usage"
Really?? The screenshot is of OSX, but he's blatantly using TeamViewer to remote into a Windows8 machine that's running 8 instances of CGMiner 3.1.1 to run 76 devices. And that Intel NUC is a 4"x4" little box with a dual-core 1.8GHz CPU. Not exactly beefy.
Sorry I imbued him with a little too much intelligence....
Seems you can get osx running on that intel stack.... with a few hacks, I initially thought he had gone that route.
Anyway .... whilst we are on the number of USB devices
Spotted another serious flaw with trying to 'tree up' a USB port to its maximum.. (actually it was my cat that found it)
A defective plug on a USB cable, allowed the cable to operate out of spec and in doing so took down a section of my miner network
(fortunately i'm on multiple controllers)... unfortunately it also burned out an ATX PSU
So maybe that is an argument for multiple cheap computers....
