For those who didn't know, you can not run exe. applications on a mac. This is a problem because all xbox 360 modding programs (modio, horizon, etc.) wont work. I recently got a mac and learned and this is how you do it.

Step 7: Then click next on the Hard Drive, Hard drive file type, and the Storage on Physical Hard Drive and click next.

Step 8: On the the File and Location page, set the gigabyte number in-between 16 gb and 30 gb, depending on your how much memory you have. Do not go under 16 gb. Windows 7 requires 16 gb to start. For me, I did 20 gb. Then click create.

Step 10: Once Windows has installed you need to download and install the Virtualbox expansion pack.
