The cable was released with the 12-inch Retina Macbook last year, and according to Apple, it is possible for the cable to fail without warning due to flaw in the design.

"As a result, your MacBook may not charge or only charge intermittently when it's connected to a power adapter with an affected cable," iClarified quoted Apple's statement as saying on Saturday.

The buyers of these cables may get a new cable if they gave Apple their mailing address when registering for MacBook.

Others can contact authorised Apple service provider, or contact Apple customer support. If any user has bought a new one, he/she is eligible for a refund.
