Hello, ? i am trying to install 10.9 to a HP XW8400 with 2x Xeon E5345 2.3GHz 8G Ram and GeForce 9500GT. I made a Stick with MyHack and try to install, when booting with -v -f after loading all Kext, System made a reset. I tried differend Kernels, even some AMD but all the same. Only if i use the Lion Kernel , witch is running fine at this System i get a Panic error after loading the Kext. Before i made the Stick, i loaded a Program called Maverickstester, and here everything is green and as a result i get "Your System is ready to install Mavericks . " Maybe some of you can help me here.
