Apple is working to release an updated version of its 85-watt MagSafe power adaptor as supplied with MacBook Pros.

A report claims the company has been unhappy with the quality of the MagSafe power adaptor and has put an engineering team to work to make a more robust version of the device.

Redesigned versions are expected next month. AppleInsider notes Apple has begun removing inventory of its 85-Watt adaptor from shelves at its retail stores and has stopped supplying it to third party resellers.
