MacBook shipments in 2014 are likely to drop by about 15% from 12 million units in 2013 to 10 million units or even 9.9 million units, according to some of Taiwan-based supply chain makers.

　　MacBook shipments in January-February 2014 were as expected, but Apple has significantly decreased shipments in March, the sources said.

　　However, other Taiwan-based supply chain makers hold the opinion that 2014 MacBook shipments estimates may not be accurate because Apple will launch new models in the second half of 2014. Apple will reportedly launch a MacBook Air with Retina display, the makers said.

　　Apple will launch a large (around 12-inch) iPad in the second half of 2014, with Quanta Computer responsible for OEM production.
