Marta Reis Posted April 3, 2014 Share Posted April 3, 2014 myHack doesn't validate my system volume and i can't proceed with OS X installation. The OS volume is currently running a UEFI Windows installation on GPT drive. BIOS has AHCI and UEFI boot enabled. I used myHack 3.3.1 and Mountain Lion InstallESD.dmg Thoughts???
