New MacBook USB charging cables are to be replaced by Apple for free because of some failures in "a limited number" of the previous design.

Apple stated that there might be some failures on the USB charging cables of before June 2005 Macbooks, according to Business Insider. Customers should take their cables to an Apple Store or contact Apple Support to get the replacement at no charge.

A new, upgraded USB-C charge cable will be given for free to every qualified client. The USB-C charge cables are also sold separately as accessories. For those who cannot come directly to Apple Stores, the replacements will be sent as long as they have given valid email addresses when they registered their products or purchased the products through the Apple Online Store.  

Apple has mentioned that, "A limited number of Apple USB-C charge cables that were included with MacBook computers through June 2015 may fail due to a design issue. As a result, your MacBook may not charge or only charge intermittently when it's connected to a power adapter with an affected cable.", according to Venture Beat.

Besides the Macbook USB Charging Cables, Apple once at a time began to replace imperfect products, including iSight cameras for iPhone 6 Plus and iPhone 5 batteries. And the Interesting thing is that Microsoft also has declared announcement to replace the charging cables for its Surface, which did not work well. As for Apple, the replacement program will continue until June 8, 2018.

Softpedia has explained that the problem with some of the Macbook charging cables might cause the laptop unable to charge or only charge irregularly, which could prompt more harm to the battery.

The company says in an announcement, "For MacBook owners who provided a valid mailing address during the product registration process or Apple Online Store purchase, Apple will send you a new cable by the end of February 2016."

The most effective method to tell if there is any design issue with your Macbook charging cable has the configuration issue or not, simply look at the wording stamped on it. Apple mentions that defective cables are stamped with the wording "Designed by Apple in California. Assembled in China." The charging cables with the new designs, which function accurately, also have a serial number after the wording.

So, there might be cables that work effectively regardless they do not have that serial number, and on the off-chance that it does, you can still prefer to replace it or not. With the free of cost from the Apple replacement program, customers are expected to get more satisfactions with the company's commitment to serve them. Moreover, the replacement program is very easy to be accessed, both through online registration or directly at the Apple Store.
