Running OS X on an Intel PC - Virtualization Method (VMware Workstation/VMware Player)
The second major way to run Mac OS X on an Intel PC is to use virtualization software such as VMware Workstation/VMware Player to install OS X inside of Windows. This method has several distinct advantages. Notably, this method is good because it allows you to run a solid base OS X. With the Hackintosh method mentioned above, you are running a modified version of Mac OS X on an Intel PC directly from the hard drive. Meaning, OS X is the base operating system.This could prove to be unstable over a prolonged period of time. Things like Mac OS X updates are not certain. After all, Mac OS X is not designed to run on a PC, and that's what the objective is.
The virtualization method allows you to run Mac OS X on an Intel PC within Windows. Because Windows is made to be installed on a PC, your base operating system will be solid, secure, and stable. Mac OS X simply installs inside of Windows, and allows you to run both Windows and Mac OS X simultaneously.
Running Mac OS X on a PC using VMware Workstation/VMware Player does have one distinct disadvantage as well. Because it requires two operating systems to run at the same time, it's eats up more of your computer's resources. This is not a strong disadvantage, but it may slow down your computer slightly. It is recommended that you upgrade the RAM memory on your computer to at least 2GB, preferably 4GB, if you don't already have that much RAM. This will help your computer to multitask more efficiently, thus allowing both Windows and Mac OS X to run smoother. For example, you will be able to designate 2GB of RAM for Windows to use and 2GB of RAM for Mac OS X to use.
We actually have a step by step guide for the virtualization/VMware Workstation/VMware Player method.
If you are to use this method, you must have a PC with an Intel processor that supports virtualization. To learn about more about processors that support virtualization, check out this page.
