MacBook Air M4 Teardown: Apple Sticks to Old Design

Apple has introduced the new M4 MacBook Air. The model features a faster processor, an improved camera, and a new color variant. But a teardown reveals that almost nothing has changed inside. The repair options remain the same, some components are still difficult to access, and the memory remains permanently soldered.

On March 5, 2025, Apple announced the M4 MacBook Air. It comes in the familiar 13- and 15-inch sizes and relies on the new M4 chip, which promises increased performance. The camera has been upgraded to 12 megapixels and supports Center Stage, a feature that automatically keeps you in the frame during video calls. Another new feature is the Sky Blue color option. A look inside, however, reveals that Apple has made few changes to the chassis and internal structure. A teardown by iFixit confirms that the design is almost identical to the 2022 M2 MacBook Air. Serviceability remains unchanged, but some problematic components remain.

Housing and ease of repair

According to iFixit, Apple uses the same chassis for the M4 MacBook Air as it does for the M2 and M3 models. This means the entire disassembly process remains the same, providing a certain degree of continuity for repairs. The USB-C ports are just as easy to replace as on their predecessors. This also applies to the battery, which is still secured with stretchable release tabs. Apple has dispensed with the special adhesive that can be released with current on the iPhone 16. Therefore, anyone wanting to replace the battery must remove it manually as usual. The Touch ID power button remains problematic. It cannot be easily replaced because the entire upper case requires removal. The same applies to the keyboard, which is not modular and can only be replaced as a complete unit.

Problems when replacing the logic board

While swapping the logic board between two identical M4 MacBook Airs, iFixit discovered an unexpected issue. Despite correct calibration, the display's True Tone feature no longer worked. This is due to Apple's software-based binding of certain hardware components to the respective device. While both laptops remained functional, this limitation could complicate repairs.

Memory still not upgradeable

As with its predecessors, the NAND chips are soldered onto the logic board. This means you can't upgrade the storage capacity later. Those who want more storage will have to choose the right configuration at the time of purchase. This is consistent with Apple's previous strategy and should come as no surprise (via iFixit).

Technical innovations

Even though little has changed on the case, the M4 MacBook Air brings some improvements.

Performance increase with the M4 chip
Better support for external monitors
Higher image quality thanks to 12 MP front camera with Center Stage
New color variant Sky Blue

The performance of the M4 chip provides a noticeable speed boost, especially in graphics-intensive applications. It also supports more external displays than previous models.

Who is the M4 MacBook Air really worth it for?

The M4 MacBook Air is a solid update with more performance and a better camera. Owners of an older MacBook Air could benefit from the upgrade. For users of an M3 MacBook Air, however, there's little reason to switch. Ease of repair remains unchanged. Many components remain easily accessible, but Touch ID and the keyboard still pose problems. The lack of memory upgrades remains a point of criticism. The conclusion of many experts is: The M4 MacBook Air is a technical update without surprises. Those who value performance will get a fast, slim laptop. Those hoping for major innovations will be disappointed. (Image: iFixit)
