Apple has issued a recall for certain USB-C cables that shipped with the new 12-inch Retina MacBook. If you have purchased this particular MacBook before June 2015, you might be using a faulty cable; it could fail without warning.
According to Apple, this issue is attributed to a design flaw with the USB-C cable. As a result, the 12-inch MacBook may not charge – or only charges intermittently – when it’s connected to a power adapter with a faulty cable. Needless to say, this is not an issue to be taken lightly, although there doesn’t seem to be any risk of damage – unlike certain USB-C cables that outright destroyed a Googler’s Chromebook Pixel 2.
It can be hard to identify if you have a faulty cable, but thankfully, Apple has provided a very easy guide to follow. If your USB-C cable only has the words “Designed by Apple in California. Assembled in China,” it is a faulty one; redesigned cables will have a serial number after said text.
If you happen to have a faulty USB-C cable, all you have to do is find an Apple authorised service provider – you can do so here – near you to receive a replacement. If you have already bought a new cable to replace the faulty one, you can contact Apple to request for a refund. More information regarding this worldwide replacement program can be found here.
