First of all, apologies if this thread is in the wrong location. Using a MacBook Air, I am a Comcast (internet) customer and have been close to going over my data allowance several times. One of the biggest data hogs (to my knowledge) is my Roku. I don't have cable, so everything that I watch is from my TV antenna or the Roku itself. I have read several websites that says you need to change a Mac address, but it isn't all that clear to me on how to accomplish this. Just thought I would ask if any of you have tried this little hack? Thanks for any help you can give.
