I bought an adapter from Mikegyver to avoid the whole issue of conversion from DC to AC and back again. Their approach of staying with DC and converting the DC voltage from 12 to whatever the MacBook requires (apparently 60 watts peak load) seems to be the most energy efficient and avoids the issue of pure vs modified sine waves in an inverter. I think the MikeGyver unit will also have less effect on my nearby compass.
On the other hand, Kensington sells a $69.95 DC to AC inverter at the Apple store, so that must work, too.
