Focusrite Saffire on Mac OSX 10.8.3

Hi there!
I'm having a problem with my Focusrite Saffire (the white one) on my Mac OSX 10.8.3.
I bought this Audio device some month ago, and two days ago I received my Macbook Pro. I've tryed to connect them, but it doesn't work.
I've saw in Focusrite page that this product doesnt work with OSX 10.8.3, because there's no firmware, but wanna make sure of this before sell it.

SOMETHING SIMILAR TO SOMEONE?
ANY HELP WILL BE WELCOME!!
PS. sorry if there's any mistake in my english.

If support for 10.8 Mountain Lion in any piece of equipment requires firmware in addition to driver support, then it all depends on when (and if) the company intends to add support for it.

If they are calling out each of the OS X releases and supporting it separately, then you should contact them to see what their plans are..
