Looks Like New M1 iMacs Are Coming Soon

 It looks like M1-based iMacs are coming soon. 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.

The updated all-in-one is expected to come in a 24-inch model and 32-inch version. Most predictions have the smaller version coming this spring, and the larger model arriving in summer/fall.
