I wanted to run the TuN software on my Macbook Pro instead of buying a new laptop just to run TuN. I did this for free, so I'd imagine if you have a few tech savvy friends that they can get you a product key for Windows. Anyone in college should have access to majorly discounted copies of Windows. A guy at my work had a Windows 7 Professional key, so I downloaded it online and used the key he gave me.
I used a Oracle software called Virtual Box downloaded from their website for free. It allows you to partition your hard drive and install Windows on your Mac.
Here's a great video on how to get Virtual Box installed and running: https://www.youtube.com/watch?v=-TCgmY3kkC4

I tried using Apple's Boot Camp but couldn't figure out how to write Windows to a USB flash drive, the option didn't exist on my machine when I opened Boot Camp for some reason. I googled around and tried to get the option to appear but failed.
So I installed VB, ran it and installed Windows 7 Professional. It works pretty good on my Mac, I designated 2GB of the 4GB I have in this machine to the Windows side of things during the setup just for reference. Then I installed the JL TuN software. At first TuN wouldn't fit into the VB window, it was in scaled mode. I switched it to Full screen mode and that got the resolution high enough to fit the entire TuN program on my screen.
There was a few tricky things I had to do to get Windows to recognize my TwK. Here's the steps I took to get Windows (running in VB) to see the TwK.
1. Create a USB filter in your VB settings while the TwK is plugged in and POWERED ON. Delete all values except VendorID and ProductID.
2. Unplug the TwK from your Mac.
3. Start Windows (the one that you applied the filter to). Let it start completely.
4. Log in if you have to.
5. Plug the TwK back in. The filter should capture it and pass control to your guest.
I had to do it in this order to get Windows to see the TwK since there's no way to eject the TwK from my Macbook, at least that I know of.
I hope this helps some of you guys that may only have a Macbook and don't want to buy a Windows machine just to run this Tun software.
Now I just have to wait for Spectrum Labs to get the UMIK-1 back in stock so I can start tuning with REW.
Good luck guys!
