Nice. Just finished my clean install. Not only did everything work that was working before but also managed to fix 2 bugs (one my own stupid fault):
1) onboard ALC887 sound now seems to work after sleep (yay)
2) I *finally* upgraded the BIOS from F4 to F15 and it got rid of the no entry boot problem that required me to use osxaptiofixdrv, where as any OS after 10.11.2 needed osxaptiofix2drv (that would stop my system booting 50% of the time!!! (YAY)
megasis - haven't tested HDMI audio as I don't use it I'm afraid.
ahubu - defiantly a platinum build. I just hope something this good can be created when it is time for an upgrade. I would love another SATA3 port, and/or M.2 plus another 4 USB3 ports.
Come to think of it, I'd recommend the UniBeast method installing Sierra over your existing install after you back it up. Upon completing the installation, run MultiBeast for Sierra for your configuration. MultiBeast will install an updated version of Clover and the appropriate kexts.
The Direct Update method was used before UniBeast & MultiBeast were updated for Sierra. So using the Uni/MultiBeast method saves you time and frustration.
Thanks but as I said in my post above I did try darkwake=0 but I'd only tried it from the Clover boot screen, so I tried adding it in to my config.plist instead. Still no joy - my machine resets when it wakes up.
