I just did a visual calibration of my new Mac using SuperCal. This color profile (attached) is for a mid-2009 13" Macbook Pro with a LP133WX3-TLA1 display panel (0610-9C9F). I set the gamma to 2.2, but you can change that with SuperCal if you like. Note that because TN panels, even such a good one as this, are very sensitive to vertical viewing angle, in a sense what I have done is simply create a profile for my preferred viewing angle. Still, it's probably a useful starting point for others as well. The mb13pro9c9f file goes in ~/Library/ColorSync/Profiles .
