A small but vocal number of MacBook Pro owners have been complaining of graphics errors affecting their machines, and the latest mumbles suggest Nvidia hardware may be to blame.
Nvidia is denying some reports which claim there's problems in some (not all) of its G84 and G86-based mobile graphics cards, while ZDNet suggests all cards with the new chips, including the GeForce 8600M GT used in MacBook Pros - may be prone to failure and overheating.
A Macworld reader who claims to have been affected by the problem explains: "The 8600M GT in my June 2007 MacBook Pro failed last night in exactly the same way as many other users - PC and Mac - have experienced.
"The computer runs as normal but has no video output - if you connect via screen sharing the System Profiler lists the display as an Intel GMA X310 with no other graphics chip available."
News of the problem first began to glimmer in July, when The Inquirer reported on these alleged problems with Nvidia hardware.
Apple's own tech support forumshave many complaints which seem to detail this problem.
