The audio level control on the mac is not "tapered" for audio. Physical volume controls on audio gear use a LOG taper. Once in a while one will run into a consumer product with a LINEAR taper volume control in the circuit - and you will notice it - most of the level change will appear in the first 30% of the taper.
Once upon a time I built an audio control surface, and used linear Penny and Giles conductive plastic linear faders. The faders were hooked up to a-d converters which remotely controlled level in a rack elsewhere. I had to create a look-up table in software to recreate the analog "feel".
