Refresh could be imminent
The base, quad-core 3.2GHz Mac Pro is low on stock or unavailable at a number of vendors, MacTrast notes. The system is listed as backordered or out of stock by resellers like Adorama, CDW, B&H Photo, MacMall, PowerMax, and J&R Electronics. Amazon has less than 10 units in stock; Frys, Best Buy, and MicroCenter also have low quantities.
The situation may suggest that Apple is about to refresh the Mac Pro. WWDC begins on June 10th, and CEO Tim Cook promised new hardware sometime in 2013. The computer hasn't received a major update since 2010, even as other Macs have undergone several iterations.
