Rumor: Mac OS X 10.7.3 beta references hint at upgraded Mac Pro units, improved video cards

It’s the beta references that provide the best hints.

Per netkas.org, Apple’s Mac Pro may be getting a long awaited refresh according to hints tucked away in the most current Mac OS X 10.7.3 beta. The beta version of the OS update includes references to an ATI video card code named “Tahiti” tucked away in the ATIRadeonX3000 driver file, which would give a new Mac Pro model even more powerful graphics processing than current models.

The article stated that “Tahiti” is a code name for ATI’s next generation AMD-based video cards, and may be the upcoming high-performance 7900-series.

The Mac Pro was last updated in July 2010, making the current configuration well over a year old.

The long interval between updates has to reports claiming Apple is questioning whether or not to continue selling its pro-level tower computer, especially since processors like the Core i7 are available, and Thunderbolt ports offer a potential alternative to the Mac Pro’s built-in expansion slots.

Referencing new AMD video cards doesn’t, however, necessarily mean new Mac Pros are on the way. Apple could simply be adding support for the upcoming cards as a build-to-order option, or developers might be misinterpreting what the references in the driver files mean.

Stay tuned for additional details as they become available.
