Hi, I have a mac pro 13 inch retina mid 2014 with 3GHZ intel core i7 and 8GB RAM, graphics - Intel Iris 1536mb. Can I install windows and run games like COD MW3 on my mac?? thanks

Yes. I believe there are even Mac versions of those games.

Windows on Intel Macs

There are presently several alternatives for running Windows on Intel Macs.

1. Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
2. Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
3. VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.

Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox.Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.

You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

You may not need to install Windows to run COD MW3 which is a major endeavor for just one game.

what they said: You may not have to do so. Recently, I ran into the same problem as you have now. I wanted to run some windows games, and that's it. Didn't want to go out and buy a copy of the Windows OS, install that, and then install my game, just wanted the darn thing to run-decently, if possible

try wineskin. go to portingteam.com and look for a game port of your game. you might get lucky on that, or as Carolyn S. said, you might want to just buy the Mac version and leave it at that.
