Whenever I try booting from my Unibeast USB to the 10.10 Yosemite installer, I get this kernel panic. I tried removing the kext dev mode, but I still got the kextd and deadbeef error. Apparently, it only successfully boots to the install screen if I boot with verbose (-v). I am trying to install Yosemite on my June 2014 Computer Build. Please help! Also, I would like to know if the serial number will change or be removed after installing Yosemite. If yes, will it count to the limit of changes?
