A developer spotted evidence that Apple is testing the M2 Apple chip, which is expected to debut first in a new MacBook Air and refreshed 13-inch MacBook Pro.

A developer source has told Mark Gurman that Apple has been testing a chip with an eight-coreCPU and a 10-coreGPU across multiple Macs.

I'm told from a developer source that Apple has been testing multiple Macs with a new chip in recent weeks that includes an eight-core CPU (four efficiency cores and four high-performance cores) and 10 GPU cores. Those are exactly the specifications of the M2 chip I detailed last year.

Apple has been testing this new chip on machines running macOS 12.3 (which should be released in the next week or two and run on the new Macs) and a future macOS 12.4, as well as macOS 13, which will be previewed in June at WWDC 2022.

The M1 Pro and M1 Max chip names were spotted in app logs ahead of Apple's Mac focused event in October.

The first significant upgrade for Apple's custom Silicon on the Mac since its introduction will be the Apple Silicon chip. Apple introduced the M1 chip in November of 2020 and has since introduced more powerful versions, including the M1 Pro and M1 Max.

An updated 13-inch MacBook Pro and a completely redesigned MacBook Air are thought to be the first things to use the new chip. Gurman said that a new Mac mini is ready to go and could launch next. As soon as the first half of the year, a new 13-inch MacBook Pro and a new iMac could be released.

Gurman still expects Apple to give a good performance on Tuesday. The new iPhone is expected to be the same size as the previous model, but with 5G and a new chip.

The A15 chip, Center Stage, and 5G are rumored to be features of a new iPad Air. Gurman said that a fourth announcement is possible with the new iPhone, iPad, and at least one new Apple Silicon Mac.

The event will start at 10:00 a.m. On Tuesday, March 8th, the time is in the Pacific. The event can be watched through the events webpage and in the Apple TV app. If you can't watch, you can follow us on social media. See our guide for a detailed rundown of everything we expect.
