Mac OS X Yosemite Installer supports more hardware (including AMD).Normally, you can bypass this limitation on Unibeast by applying the MBR patch however, Mac OS X Yosemite Installer does this for you automatically, saving you one extra step. Therefore, if your computer’s hard drive already has Windows installed on it, you won’t be able to install Mac OS X on there. By default, the Mac OS X installer will not work with hard drives that were originally formatted in Windows. You can install it on a hard drive that already has Windows installed.
