Mac/M-Audio/Driver Download Questions

Hello:

I recently entered the Mac world and need some assistance.

I believe that, alas, my Presonus Firepod has bitten the dust. So I’m looking at an M-Audio Pro160 firewire interface.

As I am new to Macs and M-Audio for that matter, could someone please tell me if I need to download a driver for the 160 from the M-Audio website, or will the Macbook link up without it?

Also, my Macbook is running on the Mac OS X 10.6 Snow Leopard. So, when I go to the M-Audio driver download page, I’m confused about which driver I should actually download: 10.6.1 32 bit, 64 bit?

Here is a link to their driver download page:

Can somebody please help me?
