Hi guys, this is my second hackintosh build in a couple months. You can find the components to my build here: http://www.kakewalk.se/forums/discussion/3975/check-out-my-build-before-i-buy#Item_4
USB 3 ports are not supported during the installation. Put USB into USB 2.0 port. Hope it helps.
Thanks. I ended up pulling my GPU until after the install. Worked fine that way. Must have also used a different USB port. I can't get the USB 3.0 working.
