Within the macOS Big Sur 11.3 beta 5, released yesterday to developers and public beta users, references to new iMac models in the operating system’s code have been identified by 9to5Mac, further bolstering reports that Apple is working on new iMacs with Apple Silicon chips.
The latest beta version of macOS Big Sur comes with codes for two new iMacs, which are identified as “iMac21,1” and “iMac21,2” …Earlier this year, Bloomberg reported that the codenames of the new iMacs with Apple Silicon chips are J456 and J457, and 9to5Mac was able to confirm that the new models listed in the latest macOS Big Sur beta have the same codename.
Last week, a developer noticed some crash reports in their app coming from an unknown iMac powered by an ARM processor. At the same time, Apple recently discontinued the iMac Pro and some configurations of the 21.5-inch iMac, which suggests that the updated iMac with M1 (or another Apple Silicon chip) is indeed coming soon.
