Even though on my first restart I got a kernel panic (I guess this was due to a removal of the USB cable connected to my Apple Magic Keyboard 2 while in the FileFaul2 Prebooter), I can confirm, that this method is working (I'm on AORUS Gaming 7 z370 with BIOS V7 and Mojave 10.4.2 with an "iMac18,3" definition).
Besides my iPhone now being charged faster, my Apple Super Drive started working, too (as it is using 500 mA current + 600 mA extra operating current).
This was the last issue I banged my head around bevor completing my (up until now vanilla build) hackintosh. So now I can finally archive my EFI and clone my system to a backup SSD and use this hackintosh for productive work
FYI: There might be a risk of the MoBo getting damaged if more current than defined by the USB 3.0 specs is flowing through the USB 3.0 ports (though this is just an assumtion as I can't really say anything substancial about that because I'm not an electrician).
Therefore, I suggest using only the USB 3.1 ports (= the red USB 3.1 Type A and the USB 3.1 Type C port) for heavy duty charging with more than 1800 mA, since
USB 3.1 ports should be build to provide up tp 5000 mA. For further reading, I also suggest
this article on USB Charging Power.
Thank you very very much for your help,
@jb007 (PS: Your System Info-Screenshot shows your iPhone S/N. You should black that out)!
@HackaShaq: Tremendous work by everyone involved! Awesome build! I suggest you add a link to
@jb007's mini guide in your build guide, since otherwise it might not be found by other users on this more than 100 pages thread, which would be sad.
