Apple launched updated models for nearly all of its Macs in 2014, aside from the redesigned Mac Pro which was released last year. The MacBook Air was updated in April and brought a price reduction along with slightly faster Haswell processors, while the MacBook Pro saw a minor update in July which also brought Haswell and Crystal Well processors that improved battery life. Last week, Apple launched a new 27-inch iMac with a high-resolution "Retina 5K" display, and updated the Mac mini for the first time in three years with Haswell processors and new Intel HD Graphics.
The company is also rumored to be working on a new 12-inch MacBook, which will feature a new ultra slim design and a high-resolution Retina display. Reports have suggested that the new MacBook will come in the iPhone color variants of Silver, Gold, and Space Gray, and will integrate fan-less internals with a Broadwell-Y low-power Core M processor along with the possible adoption of USB Type C. The 12-inch MacBook is said to be launching in mid-2015.
