Apple's European notebook repair partner company ADT has "gone bust", sources told Macworld.

The company had been handling all notebook repairs for Apple. An Apple dealer told Macworld: "This now means the channel is carrying the repairs", he explained.

Users with Apple notebooks in for repair are promised their Macs aren't held in limbo - an Apple spokesman said: "We are taking care of customer repairs that were at ADT."

People presently facing problem portables were offered the following advice: "Customers with broken notebooks should contact their local Apple Authorized Service Provider to get their portables repaired. If they don't know who that is could call the Support Contact Centre who will direct them accordingly."

However, with razor-thin margins on Apple products already, and the cost of spare parts for Macs, a reseller grumbled: "There's not enough money in repairs."
