[Aaron Nelson] of Hijinks Inc. wrote up how he installed OSX on his HP TouchSmart IQ507. It looks and works like you would expect, save for a few things. The touchscreen works, but the calibration is so far off it’s useless. The most important things, like ethernet and the memory card reader, work fine. [Nelson]’s biggest frustration is that he has to disable the on board audio every time he logs in, so that the keyboard and mouse will be recognized. He is working on improvements, and would love to hear any suggestions you have.
