Query: If you have a macbook, this is the one that works

This is the fourth adapter that I have gone through trying to get my IBM Model M keyboard to work with my late 2009 macbook pro running 10.6.4. I previously had limited success with other adapters by shutting the computer off and restarting it with the keyboard plugged in, but even then it would go dead after five minutes (let ALONE have a shred of the plug-and-play glory that my windows machines enjoyed with the same keyboard). Alas, I pulled this one out of the package and it worked INSTANTLY after plugging in and identifying the keyboard. I'm typing on it right now, so satisfied that I rushed here to share my case. It WILL work.
