Rumor: entry-level unibody MacBook set for a minor update

Vietnam is once again a source for leaked information about upcoming Apple …

The same Vietnamese forum that detailed a fourth-generation iPhone prototype last week has also obtained a model of what it claims is the forthcoming update to the entry-level MacBook. The specifications have been slightly improved over the last iteration of Apple's sub-$1,000 notebook, which got its rounded, unibody shell last October.

According to Tinhtế, the updated MacBook will come equipped with a 2.4GHz Core 2 Duo processor, up from 2.26GHz. The NVIDIA 9400M will also be updated to the same NVIDIA 320M used in the latest revision of the 13" MacBook Pro. Bus speed (1066MHz), installed RAM (2GB), and hard drive (250GB 5400PRM) remain the same. The display is still a 1280x800 pixel, LED-backlit, glossy panel, though System Profiler allegedly reports that the display is now capable of 32-bit color depth.

There's no mention of the battery, but it seems likely that Apple will include the slightly higher capacity 63.5Whr battery now standard in the 13" MacBook Pro. Combined with the more-efficient NVIDIA 320M, an updated MacBook should also be capable of a theoretical maximum of 10 hours of "wireless productivity." The included charger in the MacBook seen by Tinhtế also has the same updated MagSafe connector found on recent MacBook Pro and MacBook Air power adapters.

Updated models are expected to be released soon, based on historic upgrade cycles for the MacBook. (This would also coincide with the upcoming back-to-school buying season.) The model number for this new MacBook is reported to be MC518, suggesting this MacBook may also be joined by a rumored MacBook Air update said to have a model number of MC516. The MacBook Air is long overdue for an update based on historical release cycles.
