A French newspaper, Liberation, has published claims that some Mac Pros have been releasing toxic odors. Apple is apparently investigating claims that its the desktop is full of “seven volatile organic contaminants,” like “styrene, benzene and its derivatives.” The odor apparently takes a few different forms, described as everything from “new car smell” to “cannabis”.
The culprit is believed to be the result of a resin coating on some circuit boards and disappears after a period of time. Apparently once the product has burned in. The phenomenon seems to be only in systems built before this year. Liberation cited an anonymous researcher from the French National Centre for Scientific Research, who had his Mac Pro desktop tested for toxins after he smelled some strong odors emanating from the machine.
