About This Mac

The Late 2011 21.5-inch iMac was a simpler education-oriented configuration, using a dual-core Core i3 rather than the quad-core processors in the Mid 2011 iMac. Its Full HD display, FaceTime HD camera and Radeon graphics still formed a complete classroom desktop, with a built-in optical drive for discs. Apple reduced storage and starting memory to suit that role. This model also used Mini DisplayPort instead of Thunderbolt and omitted Bluetooth, so its similar aluminium case concealed meaningful differences in both performance and connections.
