History:
Announced on November 1, 2007, the black and white MacBooks (Late 2007) caught up with the Pro models released four months prior, perhaps in response to major criticism for leaving them behind in Apple's June refresh. Speculation also mounted that the original iPhone put every other project on hold, a claim unproven even to this day.

In a rather fortunate coincidence, these late-2007 units were released days after Mac OS X Leopard entered general availability. This allowed them to take full advantage of 64-bit applications as were being developed at the time, mostly credited to the use of Intel's GM965 core logic chipset, which in itself broke the memory ceiling of the prior model, raising said ceiling to 4 GB.

The included GMA X3100 IGP added a number of features over the prior GMA 950, including improved 3D rendering and texture support.

Though the core logic is 64-bit clean as is required for Mountain Lion, Apple's intentional use of 32-bit drivers for graphics and kernel functions has effectively disqualified this model from Mountain Lion.
