Interesting, tried this out but couldn't get it to boot in my Vbox.. Fiddled around with the settings a bit but no dice.
Using Virtualbox 5.0.4, added the OSX_VM.dmg to the storage, set the CPU to 8 processors and vRam to 128. I tested both chipset options but nothing proved successful and EFI on and off. How were you able to get this up and running?
//edit Should've checked the original link. Apparently this still worked with the developer beta, but not the public beta, or in my case, the GM candidate.
