Developer logs reveal details about the M2 in several new Macs

Apple is in the late stages of preparing several new Mac models based on the forthcoming M2 chip, according to a report by Bloomberg, which cites both developer logs and people familiar with the matter.

In recent years, Apple has transitioned nearly its entire Mac lineup 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 to run on Apple’s silicon used the M1 chip and its more powerful variants, the M1 Pro, M1 Max, and M1 Ultra.

Apple is now planning to introduce the M2, an evolution of the M1.

According to developer logs, Apple is working on the following machines:

  • MacBook Air with the M2, codenamed J413
  • Mac mini codenamed J473 with the same M2 and another codenamed J474 with the M2 Pro
  • Entry-level MacBook Pro with the same M2, codenamed J493
  • 14-inch MacBook Pro with M2 Pro and M2 Max, codenamed J414
  • 16-inch MacBook Pro with the same M2 Pro and M2 Max, codenamed J416
  • Mac Pro, codenamed J180, with a successor to Mac Studio’s M1 Ultra

The M2 seen in the logs has eight CPU cores and 10 GPU cores – that’s two more GPU cores than the most robust M1 chip. Meanwhile, the M2 Max has 12 CPU cores and 38 GPU cores with 64GB of memory – two CPU cores more and six GPU cores more than the M1 Max.

Unfortunately, the report doesn’t include the breakdown of efficiency cores versus performance cores in the M2 or M2 Max, or Bloomberg didn’t report it.

This breakdown suggests the M2 will be iteratively faster and more robust than the M1, but unsurprisingly it doesn’t seem like a radical leap or major departure.

This story doesn’t provide details on shipping dates, but it does note that the testing process is “well advanced in some cases.” However, every model listed above is not guaranteed to be shipped to consumers.

In a previous report, Bloomberg claimed that Apple plans to unveil two new Macs this summer, likely at the company’s annual developer conference in June. The most likely candidate seems to be a heavily revised MacBook Air with the M2, but an updated 13-inch MacBook Pro and Mac mini are possible, as is a new Mac Pro.
