Strong orders of Apple’s next-generation MacBook laptops are causing labor shortages within the Cupertino, California-based consumer electronics company’s Asian supply chain, a recent report claims. Citing multiple unnamed sources, Digitimes on Monday reports that heavier than expected MacBook orders have created labor shortages so serious at some Apple suppliers that they have been forced to outsource orders to meet shipment schedules. The report notes that May and June are typically slower months among PC component suppliers in eastern China, however Apple’s orders have caused recent labor shortage issues to grow more serious. New MacBook laptops and iMac all-in-one PCs will reportedly launch this summer. Apple’s new notebook computers are expected to be thinner than previous models, and both the MacBook Pro and iMac lineups are expected to include new high-definition Retina displays. Apple’s next-generation MacBook Air laptops may be updated with Retina displays as well, recent reports claim.
