Product Overview

The M3 chip brings even greater capabilities to the MacBook Air 15" with M3 chip 24GB 512GB in Starlight MC9K4X/A. With up to 18 hours of battery life (1) and a spacious Liquid Retina display, you can take it anywhere and power through work and play. The blazing-fast MacBook Air with the M3 chip is an ultraportable laptop that sails through work and play. Built for Apple Intelligence that is coming in December 2024 (2), it is the personal intelligence system that helps you write, express yourself and get things done effortlessly. With groundbreaking privacy protections, it gives you peace of mind that no-one else can access your data — not even Apple. It is lightweight and measured under 1.2 centimetres thin, so you can take MacBook Air anywhere you go. The powerful 8-core CPU and up to 10-core GPU of the Apple M3 chip keeps things running smoothly. Amazing, all-day battery life so you can leave the power adapter at home with up to 18 hours of battery life (1). The 15.3-inch Liquid Retina display (3) supports 1 billion colours. Look sharp – sound great, everything looks and sounds amazing with a 1080p HD camera, three mics, and four speakers with Spatial Audio. All your favourites, from Microsoft Office to Adobe Creative Cloud, run lightning-fast in macOS with Apple Silicon (4). MacBook Air features two Thunderbolt ports, a headphone jack, Wi-Fi 6E (5), Bluetooth 5.3 and a MagSafe charging port. And connect to two external displays with the laptop lid closed. MacBook Air works like magic with your other Apple devices, you can view and control what’s on your iPhone from your Mac with iPhone Mirroring (6), copy something on iPhone and paste it on Mac, send texts with Messages or use your Mac to make and answer FaceTime calls (7). Disclaimers: Configurable options are available. (1) Battery life varies by use and configuration. (2) Apple Intelligence is available in beta on all Mac models with M1 and later, with Siri and device language set to US English, as a macOS Sequoia update. English (Australia, Canada, Ireland, New Zealand, South Africa, UK) language support available December 2024. Some features and support for additional languages, like Chinese, English (India, Singapore), French, German, Italian, Japanese, Korean, Portuguese, Spanish, Vietnamese and others, will be coming over the course of the next year. (3) The display on the 15-inch MacBook Air has rounded corners at the top. When measured as a standard rectangular shape, the screen is 15.3 inches diagonally (actual viewable area is less). (4) Apps are available on the App Store. Software and content may be sold separately. Title availability is subject to change. (5) Wi-Fi 6E available in countries and regions where supported. (6) Available on Mac computers with Apple silicon and Intel-based Mac computers with a T2 Security Chip. Requires that your iPhone and Mac are signed in with the same Apple Account using two-factor authentication, your iPhone and Mac are near each other and have Bluetooth and Wi-Fi turned on, and your Mac is not using AirPlay or Sidecar. Some iPhone features (such as camera and microphone) are not compatible with iPhone Mirroring. (7) FaceTime is not available in all countries or regions.

At a glance

The Apple MacBook Air 15-inch is a premium thin-and-light laptop for students, professionals and everyday users who want a bigger screen without moving to a heavier notebook. Its strengths are quiet operation, long battery life, strong day-to-day performance and smooth integration with other Apple devices. The main limitation is that it has fewer ports and less sustained thermal headroom than a MacBook Pro.

Things to consider

If you need lots of built-in ports or regularly run long, heavy creative workloads, a MacBook Pro or a more specialised workstation-class laptop may be a better fit.

Student suitability

Excellent for students who want a bigger screen, strong battery life and a lightweight laptop for lectures, research, writing and general coursework.

Creative professional suitability

Good for photo editing, design work and light-to-moderate video projects; less suited than MacBook Pro models for sustained high-end rendering or heavier pro workflows.

Portability rating

8/10 - very portable for a 15-inch laptop, with a slim profile that travels well.

Battery endurance rating

9/10 - strong all-day longevity, with up to 18 hours of video playback under Apple’s stated testing.

Windows compatibility score

4/10 - Microsoft 365 and many cross-platform apps work well, but Windows-only software may require virtualisation, cloud access or an alternative device.

Key benefits

  • 15-inch display: gives you more screen space for documents, spreadsheets and side-by-side apps without stepping up to a bulkier pro laptop.
  • Slim and light design: easier to carry between home, campus and meetings than many larger-screen laptops.
  • Fanless design: runs silently, which is ideal for libraries, classrooms, shared offices and late-night work.
  • Battery life: up to 18 hours of video playback helps reduce charging stops across a full day of use.
  • Apple ecosystem integration: works smoothly with iPhone, iPad and AirPods for quick file sharing, calls and copy-paste between devices.
  • MagSafe charging: the magnetic connector helps prevent accidental cable yanks from pulling the laptop off a desk.
  • Large trackpad and comfortable keyboard: makes long writing, browsing and productivity sessions easier and more precise.
  • 1080p camera and three-mic array: supports clearer video calls for meetings, tutorials and remote collaboration.

Q: Is 24GB of unified memory worth choosing on this MacBook Air 15-inch?

A: Yes, 24GB of unified memory suits heavier multitasking than the base configuration, especially with large spreadsheets, coding tools, photo editing or many browser tabs open. It also gives more headroom for demanding apps over time.

Q: Can the 512GB storage in the MacBook Air 15-inch with M3 be upgraded later?

A: No, the 512GB internal SSD in this MacBook Air is not designed for user upgrades after purchase. If you keep large photo libraries, video files or offline project folders, choosing enough internal storage now matters more than on older laptops.

Q: Can this MacBook Air 15-inch with M3 run two external monitors?

A: Yes, the M3 MacBook Air 15-inch can run one external display while the laptop screen stays on, or two external displays with the lid closed. If dual monitors matter, note that closed-display mode is required for two screens on this model.

Q: Does the fanless design affect performance on heavier tasks?

A: Yes, this MacBook Air uses a fanless design, so it stays quiet for everyday work and short bursts of demanding tasks. For long 4K exports, 3D work or extended compiling, performance can ease back sooner than an actively cooled MacBook Pro.

Q: Is this 24GB 512GB MacBook Air 15-inch suitable for photo editing and coding?

A: Yes, this 24GB, 512GB configuration is a strong fit for photo editing, office work, study, coding and light to moderate video editing. If your routine includes frequent multicam 4K timelines or heavier 3D apps, a MacBook Pro is the better match.
