According to MacRumors, Apple appears to have removed its Intel-based 21.5-inch iMac from the shelves. The discontinuation is not surprising, as Apple has switched from Intel processors to its own M1 chip.
According to MacRumors, the 21.5-inch iMac was still in stock after Apple's October 18th Unleashed event. It didn't seem to disappear until this week. The 21.5-inch iMac cost $1,099 and came with a 2.3GHz dual core 7th-Gen Intel Core i5 processor and an Intel Iris Plus Graphics 640. It is no longer available on Apple's online store. Apple's product comparison page does not have a Buy button for the 21.5-inch iMac.
We tried to contact Apple to confirm the changes but did not receive an immediate response. MacRumors was informed by Apple that the machine has been discontinued and will not be available for purchase online or at its retail stores.
Apple hasn't discontinued its entire Intel-based iMac lineup, but it is still selling the 27 inch Intel-based iMac at a starting price $1799.99. MacRumors reports that you can still buy a refurbished 21.5 inch iMac at Apple's online store.
Apple removed the 512GB and the 1TB versions of its 21.5-inch iMacs in March. The company has been gradually phasing this model out for a while. Apple's thinner, brighter M1-powered iMacs were unveiled in April. It makes perfect sense that Apple should clear space on its shelves.
