New iMacs and Mac minis confirmed to use NVIDIA chipsets

Apple's next-generation iMacs and Mac minis will adopt the same NVIDIA chipset platform found at the heart of the company's most recent notebook overhaul, new findings confirm once over.

A member of the InsanelyMac forums was recently rifling through the extension files that ship with the latest MacBooks and MacBooks Pros and discovered references to a "Macmini3,1" and "iMac9,1."

Running System Profiler on Apple's most current iMacs and Mac minis reveal the model number of those systems to be "Macmini2,1" and "iMac8,1," meaning the configuration files included with the company's latest notebooks are for still unannounced models.

Specifically, the extension file of interest pertains to a Mac's System Management Controller and Advanced Configuration and Power Interface (ACPI_SMC_PlatformPlugin.kext). It includes a variety of information, including strings that identify the supporting chipset of each Mac.

The entries for the unannounced iMac and Mac minis list their chipset as the "CFG_MCP79," which is the same exact NVIDIA MCP79 platform employed by unibody MacBooks, MacBook Pros, and MacBook Airs, which are similarly identified in the same file as the MacBook5,1, MacBookPro5,1, and MacBookAir2,1.

Also of interest is that the entries for the new iMac and Mac mini are dated 2008, which may provide evidence to support claims that these systems were originally targeted for a release in the November time frame but were pushed into the first quarter of the year due to unexpected delays.

While announcing its new notebook offerings in October, Apple had indicated that it would be using more of NVIDIA's technology in its Mac computer line going forward.
