Other specs say it comes with either the Intel Core 230 or Core 330 CPU, both of which *should* work with OSX. The 230 is basically a 64-bit version of the Atom N270 (1.6ghz, 512kb L2 cache, 533mhz FSB, 4W power dissipation vs. 2.5W for the N270). The 330 is actually a dual-core 64-bit version (1.6ghz, 1mb L2 cache, 533mhz FSB, 8W power dissipation). Comparison table here
(all the same info I just gave). They're both built on the Diamondville 45nm architecture, same as the N-class CPUs. They should all support the same instruction sets.
Buy one cheap tomorrow or on Cyber Monday and try it out, if it doesn't work you can sell it for a profit (hopefully).
