Best Buy Pulls 12-Inch MacBook, Fueling Hopes for April Refresh
The authorized reseller now lists all 12-inch MacBook models as "no longer available" on its website, whereas some remained available for purchase or in-store pickup as recently as this weekend.
Select MacBook Air models are also on sale for $150 off, potentially signaling that a broader Mac refresh could be imminent. Most current machines are historically due for an update, and appropriate Intel Skylake processors are now widely available. However, it should be noted that Best Buy frequently offers sales on Apple products.
Last month, reference of an early 2016 Retina MacBook, which has yet to be released, was discovered within OS X's System Image Utility application, spurring hopes that Apple will refresh the 12-inch MacBook by late April.
Apple has historically used the "early" model identifier for devices that launch during the first four months of the year, so Best Buy removing 12-inch MacBook stock is yet another indication that Apple may refresh the notebook within the next two weeks. If the refresh is in May or later, a "mid 2016" model identifier will likely be used.
Our Mac Buyer's Guide indicates that it has been 374 days since Apple released the current 12-inch MacBook on April 10, 2015, so it would be appropriate timing for a refresh. The notebook will likely be powered by Intel's low-power Skylake Core m3-6Y30, Core m5-6Y54, and Core m7-6Y75 processors.
Update: Select 12-inch MacBook models are also listed as out of stock at MacMall.
