This is according to a report from Consomac who spotted these model numbers at the Eurasian Economic Commission’s database, which has in the past proven to be pretty reliable at predicting new products from the company. There are quite a number of Apple models spotted, some of which are new, and some of which are old.
As pointed out by 9to5Mac, the old model numbers include A2147, A2158, and A2182, which haven’t been released yet but were actually spotted last year. The main difference is that these models have been updated from macOS Catalina to Big Sur. The new model numbers also include A2337 and A2338, which cover laptops, and A2348, A2438, and A2439 which refer to desktops.
There are so many model numbers, but it is possible that these model numbers are simply variants of a couple of products. It is anyone’s guess as to which computers they might be referring to, so we’ll just have to wait and see.
