macOS Big Sur 11.3 Beta 5 Includes references to two unreleased iMacs

It is rumored that Apple is working on new versions of the iMac desktop computer, and a launch could take place in the near future, based on the new signs found in the macOS Big Sur 11.3 beta that was released this morning.

Conformable 9to5Mac, there are references to two new ‌iMac‌ models in macOS Big Sur 11.3 beta 5, identified as “iMac21,1” and “iMac21,2”. The new Macs use the code names J456 and J457, which were first revealed earlier this year by Bloomberg.

We don’t know yet when Apple will refresh the ‌iMac‌ range, but there are new versions of the 21.5 and 27-inch 21iMac‌ models in the works. Rumors suggest that the new iMacs will have a design similar to Pro Display XDR, with thin frames and no metal chin.

Rather than a curved back design, the new ‌iMac‌ models will have a flat back and at least one of the new models will measure between 23 and 24 inches. Apple’s silicon chips will be included, and some dubious rumors have indicated color options that match the iPad Air’s colors.

Apple recently discontinued the iMac Pro, which was a state-of-the-art ‌iMac‌ option launched for the first time in 2017. With signs of new iMacs in the current Big Sur beta and iMac Pro discontinued and exhausted, we could see ‌iMac‌ updated models in a not too distant future.
