Apple is in the late stages of readying several new Mac models built on the forthcoming M2 chip, according to a report from Bloomberg citing both developer logs and people familiar with the matter.

Over the past couple of years, Apple has been transitioning nearly its entire Mac product line from Intel's chips to Apple's system on a chip, which includes a CPU, GPU, NPU, ISP, and more. The first generation of Macs running on Apple's silicon used the M1 chip and its more powerful variants, the M1 Pro, M1 Max, and M1 Ultra.
