The Mid 2011 Apple iMac 21-inch (MC309B/A) were the first generation of the smaller iMacs to be fitted with quad core processors as standard and Thunderbolt ports. This entry level model is powered by a second generation “Sandy Bridge” quad core 2.5GHz Intel Core i5 (2500S) processor paired with AMD Radeon HD 6750M graphics. The Mid 2011 Apple iMac models were the latest models to still include the sorely missed SuperDrive and FireWire port.
