Apple will finally announce updated MacBooks in June, DigiTimes claims. The site quotes supply chain sources, who say that parts shipments are expected to pick up significantly that month as Apple escalates MacBook production. Shipments are predicted to peak in July, once capacity is reached; industry sources suggest that Apple will grow MacBook shipments by as much as 50 percent in 2012, vastly outdoing the pace of Windows PCs, even if the latter will likely still be the most dominant computer platform by far.
