The latest beta seed build of Apple’s upcoming Mac OS X 10.6.2 update references a slew of new Apple notebooks. Per Spanish web site applesfera.com, entries exist in the 10C531 build that make references to “MacBook Pro 6,1″ and MacBook Pro 6,2,” neither of which exists in the market. The current MacBook Pro notebooks range between 5,1 and 5,5.
The move from 5 to 6 in the naming scheme points to these being significant revisions rather than minor refreshes. Both may be signs of early preparation for MacBook Pro portables unofficially expected at the start of 2010. Apple is likely to be one of the earliest adopters of Intel’s upcoming Arrandale processors, which in January should bring the Core i5/i7 architecture to more power-efficient dual-core chips that would fit in a thin-and-light notebook’s enclosure and require a new underlying platform.
