The latest beta version of macOS Big Sur comes with codes for two new iMacs, which are identified as “iMac21,1” and “iMac21,2” — it’s worth mentioning that these numbers are not related to display size.

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.
