Installed dp4 and my Mac Pro 2008 can no longer boot it. Stuck on apple logo. Spinning progress indicator spins, then pauses, then spins again getting "darker" each time until it appears black and you can no longer tell its spinning at all. Just a warning...
Update: I was able to get it to boot by unplugging my oculus vr from the dvi port.
