Awesome.
Personally, I don't use the wifi anyway (too slow), so that's not a problem. Bought a USB3<->1GbE adapter (AX88179 based) for wired connection, which seems good. ~70MB/s sustained transfer rates.
For audio, using a USB headset (working ok).
Not using the inbuilt the keyboard/trackpad. Instead, using a separate keyboard, tablet, and a 2nd monitor.
I'll give Sierra a shot at a later date, now you've mentioned the Clover thing. When I was first attempting to Hackintosh this thing I didn't realise that the USB port on the front right side gets treated differently from the one on the front left side.
The USB stick I have wouldn't UEFI boot (was using the front right side port), so went with the Legacy mode.
Only discovered later on (accidentally) that the same USB stick boots UEFI fine... when plugged into front left USB port.
Seems a bit weird, but I guess it's just the way the internal's are wired together in the laptop.
