Now that Mac OS X computers are powered by Intel processors, Mac and PC hardware is the same, opening a new world up to Mac owners. Not just in the realm of some new software, but also being able to run Windows on our Macs. Think of all you could do by having both. You obviously already have since you’re here. But consider it a bit more in-depth, as the reasons for your wanting to use Windows on your Mac will help make sure that you have two smooth running operating systems. To do that though, you will need to choose a program to help run Windows on your Mac.

Will You Need Windows?

If you haven’t already chosen and purchased a copy of Windows you will need to do that before you install most of these programs. There is one exception though, and that is if you’re using a program called CrossOver, but you can read more about that below. To know which Windows version you should use, you can go to “Run Which Windows on Mac”. Along with this article, it’s part of my series on “How to Run Windows on a Mac”. Don’t worry, you’re still fine as we’re just on step 2. Step 3 will be next and will cover the actual installation of the two. Until then, read on…

Boot Me Up Scotty!

Yes, I know, it’s “beam me up” but that didn’t fit, and we’re all techies here so we get the reference. Booting up your Windows operating system on your Mac will require a program. There are several to choose from, including ones that will simply boot it up as another OS, and others that will allow Windows to run virtually alongside your Mac’s OS X. So, which to choose?

There are many alternatives for you to choose from, but only 4 that truly stand out. Your 4 choices are:

Apple’s Boot Camp: This program gives you the option to boot directly into Windows when you start your Mac.

CrossOver (a.k.a. CodeWeavers): The only one to not require a copy of Windows, this program tricks your Windows applications into thinking that there really is a copy of Windows installed.

Parallels Desktop & VM Fusion: These are not the same program, but they work the same way. Which is by allowing you to install and run a copy of Windows from inside your Mac OS X.

Now that you understand some of their differences, you now need to know how these differences can affect the programs you’ll be using. That’s why I asked you to put on your thinking cap earlier when asking you to consider the reasons you’re using Windows on Mac. If your answer was that you want to play some of your Windows / Microsoft games on your Mac, then which program you use to run Windows will matter. In this case you should use a program that allows you to boot into Windows when you start your Mac. This option would be Apple’s own Boot Camp.

Virtually Thinking?

If you’re repeatedly running Windows on Mac then you should probably go the virtualization route. What this means is that you’ll be able to run the two operating systems side-by-side, without the need to reboot. This is possible with Parallels, VM Fusion, and CrossOver. One of the downsides to these programs, at least with Parallels and Fusion, is that they may negatively affect your Mac’s performance due to the larger demand on its resources.

Each of these programs have a free trial, so if you decide that going the virtualization route is for you, then you can download them and give them each a try. Of course you will need to have a copy of Windows ready for Parallels and Fusion, but when trying out CrossOver you’re good to go. Play around with each one for a few days and try doing similar things on it, like opening Numbers on Mac and Excel in Windows. Then watch to see how each one handles it. It’s a good time to toss some heavier programs at it as well, may as well see how much it can handle before you buy it.

If your choice comes down to Parallels or VM Fusion, you will not likely be disappointed with either one. In fact, in a side-by-side comparison, Fusion beat Parallels by a mere 4%. The only time you may be let down is if, as I said earlier, you’re using it to run games or 3-D programs in Windows. For that you’ll want to use Boot Camp. You can even use Boot Camp in conjunction to these programs, again having the best of both worlds.

Let’s Go!

Where are you going? We’re moving on to step 3, which is where we will now install Windows on your Mac. When you’re done, or even now, you can review a few other considerations that you’ll need to know when running Mac on Windows; such as how much RAM you’ll need to set aside and how to avoid viruses, but for now you’re ready to go. So come on, follow me to Step 3!
