Leaked Files Show A15 MacBook Test; A18 Pro Close

• Apple kernel debug files show Apple tested an unreleased MacBook running the A15 Bionic.
• A separate A18 Pro-based MacBook entry (J700) looks like a defined product configuration with MediaTek "Sunrise" wireless.
• The A15 listing appears to be a test platform (J267, mac14p, H14P); the A18 Pro MacBook is more likely the shipping low-cost model.
• Rumors point to a 13-inch, A18 Pro low-cost MacBook arriving next year in multiple colors.

What the kernel debug kit reveals

Internal kernel debug kit files that leaked from Apple earlier this year include Mac-related entries naming two distinct MacBook configurations. The files were briefly accessible on Apple’s site before being pulled, and they provide identifiers and platform labels used by Apple engineers.

A15 test platform: J267

One row in the dataset explicitly describes an unreleased MacBook configuration running an A15 chip. The entry is listed under project "mac14p" on a platform labeled H14P and is believed to correspond to internal codename J267.

Evidence suggests this A15 entry was a test or developer platform rather than a product intended for retail. Apple has used older iPhone chips as developer kits before — the original Apple silicon Developer Transition Kit used an A12Z — but consumer Macs have shipped with M-series silicon since the transition began.

A18 Pro MacBook: J700 looks product-ready

The same dataset contains a separate MacBook entry tied to the A18 Pro, identified as J700. Unlike the A15 test entry, J700 is accompanied by subsystem details, including a "Sunrise" wireless subsystem attributed to MediaTek.

Because J700 lists a defined internal codename and specific wireless subsystem, it reads more like a finalized product configuration — strengthening rumors that Apple plans a low-cost MacBook powered by an iPhone-class chip.

Why an A15 MacBook shipping in 2026 is unlikely

The A15 Bionic debuted in 2021, so releasing a Mac with that chip in 2026 would be atypical and leave the product behind current performance expectations. An A18 Pro-based MacBook would be significantly more capable and aligned with Apple’s recent silicon strategy.

Implications for a low-cost MacBook

Industry reports and the J700 entry suggest a 13-inch low-cost MacBook with the A18 Pro could launch next year. Leaks point to color options including silver, blue, pink, and yellow — aiming to position the device as an affordable, consumer-focused entry in the Mac lineup.

In short, the leaked debug files reveal Apple experimented with an A15 MacBook as a test platform, but the A18 Pro configuration appears to be the candidate moving toward production.
