The USB Driver on Mac is actually a bootloader, that tells to the host what the AxeFx "should" be - a class compliant device - that means, as a class compliant device, the axefx gets all his driver code out of an extension called AppleUSB Audio - this is an I/O kit based kernel driver, part of the operating system and based on the USB.org Audio Class 2.0 specs. There is no dedicated mac core-audio/core midi driver up to date....
It's installed correctly if you see it here: Your Hard Drive/Library/Application Support/Fractal Audio/AxeFxIIso you are saying that you can not see where the driver is installed? not fully understand what you are saying.
and how do I know for sure that it is installed correctly?

When the axe-fx is turned on and usb cable is connected, open your system preferences and look in "sound" you'll see the axe-fx listed as a device. In the Audio Midi Setup application located in applications/utilities you'll see it as both an audio and a midi device.
If you power down the axe-fx or unplug the midi cable while axe-fx is still powered on, the axe-fx will disappear from the lists for audio devices and it'll still be viewable but be greyed out as a midi device in the MIDI Studio window of Audio Midi Setup. Power it on or plug in USB while powered on and the opposite happens.

I think
Everything is there in the Application Support folder and Axe Edit is working correctly. However in the System preferences sound I don't see the Axe fx. I am running OSX 10.6.8. Maybe the OSX is the reason? because 10.6.8 doesn't allow Audio-USB?
Yes.
On 10.6.8 (snow leopard) MIDI over USB is supported (AE 3.0, Fractal-Bot), not Audio over USB.

so you are saying that you can not see where the driver is installed?
