M3 Air adds dual external display support for the first time. Same stunning design with Wi-Fi 6E.
The March 2024 MacBook Air update was a comparatively quiet, spec-focused refresh that nonetheless delivered one particularly significant and long-requested capability: for the first time in the Air's history, the machine could finally drive two external displays simultaneously while its own built-in screen remained active, a limitation that had persisted since the very first Apple Silicon Air arrived and one that had genuinely frustrated buyers who needed a multi-monitor setup for spreadsheet-heavy or multitasking-intensive work but didn't want to pay the premium for a MacBook Pro just to unlock that capability. The external chassis and 13.6-inch and 15-inch display options carried over essentially unchanged from the M2 generation's redesign, with the same MagSafe charging, flat-sided profile, and color options including Midnight and Starlight, meaning this update's story was almost entirely about the M3 chip's internal improvements and that unlocked dual-external-display support. M3 itself, built on the same advanced 3-nanometer process as the concurrent MacBook Pro line, brought modest CPU and GPU performance gains along with support for hardware-accelerated ray tracing, features more likely to matter to enthusiasts and light creative users than the Air's traditionally mainstream, everyday-productivity audience. Reviewers treated the release warmly but without great excitement, correctly identifying the dual-external-display support as the genuinely meaningful headline feature for a meaningful subset of buyers, while noting that most everyday users upgrading from an M1 or M2 Air would notice only incremental real-world speed differences. The Air's continued position as Apple's best-selling, most broadly recommended laptop remained entirely intact, and this update simply removed one of the last remaining feature gaps separating it from the pricier Pro line, reinforcing the Air's identity as an extraordinarily capable, thoughtfully refined everyday machine for students, writers, and mainstream consumers who valued its silent, fanless operation and now, finally, greater display flexibility for anyone connecting it to a proper desk setup.
Built on TSMC's 3nm process, this M3 configuration offered an 8-core CPU and up to a 10-core GPU with hardware-accelerated ray tracing and dynamic caching, modest but real gains over M2 while remaining entirely fanless in the Air's thin chassis. Compared to contemporary Intel Core Ultra and AMD Ryzen mobile chips, M3 maintained Apple Silicon's strong efficiency lead, and its improved display controller finally enabled the Air to drive two external monitors simultaneously alongside its built-in screen, addressing a long-standing feature gap versus the MacBook Pro line.

2024
Launched as the debut OS for the M3 MacBook Air.

2024
Brought Apple Intelligence features fully supported by this M3 hardware.

2025
Remains actively supported and updated as of the most recent macOS releases.
The M3 MacBook Air was well received primarily for finally adding dual external display support, with the underlying chip upgrade seen as a solid but modest improvement.
Dual external display support is the feature Air buyers have been asking for since the M1 model launched, and it's genuinely great to see Apple finally deliver it.
M3 brings modest, sensible gains over M2, though most everyday users won't notice a huge difference unless they specifically need the new display flexibility.
This remains the laptop we recommend to almost everyone, and closing the multi-monitor gap with the Pro line only strengthens that case.
It's a quiet update on the surface, but for anyone who wanted a proper two-monitor setup without buying a MacBook Pro, this is exactly the fix they were waiting for.
