Corsair M60

I've been looking at upgrading now it seems the upgrade has been forced upon me as my old DeathAdder (1800dpi) has been destroyed by my new dog. I use two computers to play video games, a 2008 Intel based Macbook and a Windows 7 HP computer. The DeathAdder has support for both platforms, but the mouse I was looking at getting was the Corsair M60, which only has support on Windows, even though I know most people say that the software is garbage. THe reason I am contemplating the M60 is because it has the sniper button, and one of the three games I play is Battlefield 3, the others being World of Warcraft and Skyrim. I like the option of having the "sniper" button located on the mouse, as I struggle with shots when zoomed in. The issue I am concerned with is being able to use the mouse on a Mac. Are there any pieces of software that would allow me to do this or does anyone know if I can do plug and play, much like what I was able to do with my older DeathAdder. My other contemplation is getting the newer version of the DeathAddder, but I like the idea of having a couple extra buttons. Your thoughts and opinions are most welcome.
