The Apple MacBook Air “M3″ 8 CPU/10 GPU 15” (2024) redefines what users can expect from a large-screen ultrathin notebook. With Apple’s next-gen M3 chip, a vibrant 15.3-inch display, and refined hardware, this fanless model blends performance, display size, and portability like no other MacBook Air before it.
Designed for professionals, students, and creatives, this 15-inch model is a scaled-up version of its 13-inch sibling, offering more screen space while retaining a lightweight and elegant aluminum build. The larger chassis doesn’t add bulk—just better thermals and immersion.

Display and Design Highlights
The standout feature of the MacBook Air M3 15″ is its 15.3-inch Liquid Retina display. With a native resolution of 2880×1864 pixels, the screen supports over 1 billion colors, Wide Color (P3), and Apple’s signature True Tone technology. Whether you’re editing video, coding, or streaming content, the visual fidelity is crisp and immersive.
Despite its size increase, the chassis retains a sleek, ultra-thin profile with no fans. This makes the device silent during operation and ideal for noise-sensitive environments. The Midnight color option is enhanced with an anodized finish that reduces fingerprints, a welcome improvement for frequent travelers and professionals.
Performance and Memory Upgrades
The M3 chip with 10-core GPU delivers strong graphics performance, making this MacBook Air suitable for light video editing, gaming, 3D rendering, and software development. The 16-core Neural Engine boosts AI workflows, while 100 GB/s memory bandwidth ensures snappy multitasking.
RAM options now start at 16 GB, with the new 24 GB configuration offered at the same price tier previously reserved for 16 GB builds. SSD configurations start at 256 GB, though most professionals may opt for 512 GB or more.
Battery and Charging Options
Thanks to a 66.5 Wh battery, this MacBook Air lasts up to 18 hours on video playback and 15 hours during web use. Apple ships this model with a 35W Dual USB-C charger, but users can opt for a 70W fast charger at no additional cost, making it a good value for those on the go.
