About This Mac

The standard Late 2015 21.5-inch iMac refreshed Apple’s compact desktop with newer Intel processors and integrated graphics while retaining a Full HD screen. Dual-core and quad-core configurations covered different levels of everyday work, with Thunderbolt 2 available for external displays and fast storage. Its slim enclosure still combined the computer, camera and speakers into one tidy unit. The new Retina 4K iMac was the important alternative for sharper text and detailed photographs, while this model’s soldered memory made the original configuration a lasting decision.
