The first beta of OS X 10.8.3 has led to speculation that Apple is preparing to launch new Mac Pros in 2013.
The beta for the upcoming update to the Mac operating system contained driver support for the Radeon HD 7900 series of powerful graphics cards from Advanced Micro Devices.
AppleInsider suggests that due to the support for AMD's "Tahiti" GPUs in the next version of Mac OS, Apple is working on an updated Mac Pro.
To add credence to the speculation, back in June, Apple CEO Tim Cook promised graphics professionals and dedicated users of Apple's PC that new Mac Pros would be released in 2013.
The pledge came after consumers voiced their concern regarding Apple's possible exclusion of its workstation from its plans due to a shifted focus from Mac products to the iPhone and iPad lineup.
Meanwhile, Apple's redesigned, super thin 21.5-inch iMac will be available from Friday, while the 27-inch model launches in December.
