The reputation a lot of Mac fans have of being smug and holier than thou certainly won't be helped by the news from the US that Apple is apparently refusing to repair computers that show signs of cigarette smoke.

According to reports from Mac owners seeking repairs under warranty, the company claimed evidence of cigarette smoke inside the machines in question constitutes a "biohazard".

Health hazard

One, presumably ex-, Mac user was told that "Apple would not require an employee to repair anything deemed hazardous to their health."

As the company's Applecare warranty does not specifically exclude machines showing the presence of smoke or nicotine from repair, it's likely that Apple will fall back on its 'extreme environment' clause that lets it off the hook.
