Bloomberg News reported on Thursday that Apple has started internal testing of multiple Mac models with next-generation M2 CPUs, citing developer logs.

According to the logs validated by persons familiar with the subject, Apple is testing at least nine Mac models with four unique M2-based CPUs – the successors to the present M1 series – with third-party programs in its App Store.

According to the source, Apple is also testing a Mac mini with an M1 Pro CPU, the same processor seen in the entry-level 14-inch and 16-inch MacBook models.

Macs will get replacements

In March, Apple announced a faster CPU for a new desktop, marking a turning point in the company’s push to power its gadgets with microprocessors developed internally.

This year, Apple unveiled two new MacBook Pro models, both of which operate on more powerful in-house CPUs, further separating it from former supplier Intel.

The iPhone maker announced that the M1 Ultra would be the last chip in the current generation’s lineup. Bloomberg did not predict that the Studio would get a replacement like the Mac models. According to the report’s writer, Mark Gruman, there’s reason to believe Apple is also developing an M2-powered MacBook Air with a 10-core GPU.

No iMacs on the list

The M2 Pro and M2 Max processors will apparently be used in the higher-end workstations, with the Max featuring 12 CPU cores and 38 graphics cores (two CPU and six GPU cores extra compared to the M1 Max).   The M2 Pro is also available as a Mac Mini alternative, and Gurman believes the Mac Pro will have a replacement for the M1 Ultra.

iMac models are noticeably absent from the list. There’s no word of a follow-up to the M1-powered 24-inch all-in-one or a replacement for the 27-inch iMac, which was recently discontinued.
