Apple tv, mavericks, airplay mirroring and mid 2009 macbook pro...

I just bought an apple tv, and after updating to mavericks... I find out that airplay doesn't allow me to mirror my mac because is a mid 2009 macbook pro, even tho apears to be other providers that by $9,99 offer you a software which actually works. It works perfectly on my iPhone 5, my iPad 3rd gen... but not my most usefull tool!!!

I understand Apple doesn't want my computer to warm up... but it actually does already. I am a brand advocate, I transpire apple through my pores, but why do you test me so many times? I feel like some catholic cristian speaking to a God that has letted him down so many times and it finds himself saying... "Mate, if I don't get a sign from you soon, I'll start thinking seriously about budism."

So hear me here, please, software update to all macs support airplay mirroring!!! We have your tools, just make it fair.
