Don't I need a version of Windows?
I am a mac guy, and have been one since the begining (1984). I have been running RF 7 on my Macbook Pro 15" (2.7 ghz Intel Core i7, early 2013) since it came out. I have avoided the 7.5 "upgrade" due my resistance to send these people any more of my money.
You first have to get a version of windows that is not an upgrade but a full copy. You can get either the full retail or a OEM kit. The OEM is cheaper, but it the serial number is locked to a specific laptop or computer. The retail version can be moved if you are planning on a new laptop in the future. I would recommend Windows 7 over 8, at least until MS fixes it one more time.
The next step is to partition your hard drive. This is relatively simple, but you will need a large enough one to accommodate all of windows. With the newer laptops with flash based drives this can be a problem. I currently have 120 gb for my windows partition. If you need all the space for OS 10, and don't have enough room for windows then I would not bother. Before RF I have gotten away with a 16 to 32 gb partition with no issues. Just like most video games, RF takes up a lot of disc space.
For flying CP helicopters I have switched to using CGM Heli Simulator. It is native mac application. I can even use my RF controller.
