Bloomberg reported on Thursday that Apple has begun internal testing of multiple Mac models with next-generation M2 chips, referencing developer logs.

According to the logs, which were validated by persons familiar with the topic, Apple is testing at least nine Mac models with four different M2-based CPUs – the successors to the present M1 series chips – with third-party apps in its App Store.

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

Apple announced its faster chip called M1 Ultra (by linking two M1 Max chips) for a new Mac Studio in March 2022, highlighting a major shift in the company’s push to power its devices with microprocessors created in-house.
