Thanks for the guide! Upgraded from Yosemite.
I had to execute the Toleda Audio Patch for sound and re-enable TRIM support.
Also - I'm running little snitch, make sure you update that too.
EDIT - Spoke too soon. USB 2 & 3 work from the back ports - however the front usb headers are not recognized. Small price to pay as I notice that my Safari/youtube performance has dramatically improved. I'll just need to hang more off the back ports. Also - VMWare v8.0.0 and v8.0.1 running with a Win7 guest machine - the guest loses the second monitor. (yes I've reinstalled the vmware tools, etc.)
EDIT 2 - USB now working after applying the Rename patch (Rename EHC1 to EH01 & EHC2 to EH02.) VMWare still acting weird with dual screens - however there is a work around that 're-enabled' the second monitor for guests.
