Apple Tested a MacBook with the A15 Chip
An internal Apple kernel debug kit indicates that Apple has experimented with a MacBook powered by the A15 chip, alongside another MacBook built around the A18 Pro, which appears closer to a ship-ready product.
This information comes from internal kernel debug kit files used by Apple engineers. The kit was accidentally published on Apple’s website earlier this year and was removed after details started circulating.
Within the Mac-related entries, one line explicitly describes an unreleased MacBook configuration running an A15 chip. The entry is listed under a project label “mac14p” on a platform named H14P. MacRumors suggests this A15 MacBook could correspond to the codename J267.
In the same dataset, there’s another MacBook entry tied to the A18 Pro. It carries the identifier J700 and is described as using an A18 Pro chip with a “Sunrise” wireless subsystem credited to MediaTek. Compared with the A15 test configuration, the A18 Pro MacBook entry reads more like a defined product configuration, as it’s associated with a specific internal codename and detailed subsystems.
It’s also highly unlikely that Apple would release a Mac powered by the A15 Bionic in 2026, nearly five years after the chip’s introduction. A MacBook with the A18 Pro would be substantially more capable, future-proof, and aligned with Apple’s current chip lineup.
The A15 MacBook was almost certainly used as an unreleased test platform ahead of the broader rumor cycle about a low-cost MacBook set for release next year, potentially powered by the A18 Pro chip and paired with an iPhone chip. Historically, Apple’s first silicon Mac mini Developer Transition Kit used an A12Z, but all consumer Apple silicon Macs have since used M-series chips.
Rumors suggest the low-cost MacBook would debut next year, featuring the A18 Pro chip, a 13-inch display, and color options including silver, blue, pink, and yellow.
