Apple has discontinued 2 models of the 21.5 inch iMac computer, after rumours of an upcoming refresh for the iMac line. Customers can no longer purchase the 512GB and 1TB variants of the smallest iMac, although the 256GB version is still for sale. The iMac Pro model had also recently been discontinued. Apple is widely expected to refresh its iMac line-up with their in-house Apple Silicon ‘M1’ processors, already included in the new Macbooks and the Mac Mini. The redesigned iMacs may also come with a thinner bezel around the edges, and FaceID security recognition.
