Last August, Apple revised the design and replaced its MagSafe adapters for consumers, and as early as October 2007 it was getting ready to bring in new 85-watt MagSafe adapters for MacBook Pros following a raft of complaints.
According to AppleDefects.com, which had pictures, the adapters could get so hot that cables melted.
Now it’s all culminated in a class action law suit, brought in California by Naotaka Kitagawa, Timothy Broad, and Jesse Reisman. According to a report in The Register, the suit covers both the 85-watt and 60-watt adapters, alleging that the cable "dangerously frays, sparks, and prematurely fails to work."
What’s perhaps surprising is that this isn’t the first time Apple has faced a suit like this. Eight years ago it settled a suit concerning adapters for the PowerBook G3, replacing over half a million adapters.
