UPDATE: For Mac OS X Sierra please follow this post How to install Mac OS X Sierra 10.12 on VirtualBox?
Years ago I wrote a post for installing Mac OS X on VirtualBox. At that time, the version of Mac OS X was 10.7.3 Lion. The installation may not work with current version of VirtualBox anymore. Therefore, I would like to make another post for updating this hack. This time, we’ll use VirtualBox 4.3.26 for hosting Mac OS X Yosemite 10.10 in Windows 8.
