Product Overview

The M3 chip brings even greater capabilities to the MacBook Air 15" with M3 chip 24GB 512GB in Silver MC9J4X/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 MacBook Air 15-inch with M3 chip is a premium thin-and-light laptop for students, professionals and everyday creators who want a larger screen without moving to a heavier pro model. Its strengths are portability, quiet operation, long battery life and smooth macOS performance for daily tasks and light-to-moderate creative work. The main limitation is fewer ports and less sustained performance than MacBook Pro models for demanding specialist workloads.

What it’s great for

  • Everyday Productivity
  • Office Work
  • Student Computing
  • Remote Work
  • Travel
  • Web Browsing
  • Media Streaming
  • Light Creative Work

Where it works best

  • Home Office
  • University Campus
  • Corporate Office
  • Shared Workspaces
  • Coffee Shops
  • Frequent Travel

Who it’s for

  • University Student
  • Everyday Professional
  • Remote Worker
  • Business Traveller
  • General Home User
  • Light Creative User

Things to consider

It prioritises portability and quiet everyday use over expandability, so users needing more ports, upgradeability or stronger sustained performance for heavy video, 3D or engineering workloads may be better served by a MacBook Pro.

Student suitability

Excellent for university students who want a bigger screen, long battery life and easy portability for notes, research, assignments and video calls.

Creative professional suitability

7/10 - strong for photo editing, design and light-to-moderate content creation, but not the best fit for long, intensive pro workflows compared with MacBook Pro models.

Portability rating

8/10 - very portable for a 15-inch laptop, though not as compact as the 13-inch Air.

Battery endurance rating

9/10 - excellent all-day battery performance for general work, study and media use, with Apple ratings up to 18 hours of video playback.

Windows compatibility score

5/10 - good for browser-based and cross-platform apps, but some Windows-only software and niche workflows may need alternatives or virtual solutions.

Key benefits

  • 15-inch display: Gives you more room for documents, spreadsheets and side-by-side apps while staying easier to carry than many larger performance laptops.
  • Fanless design: Runs silently, which is ideal for study spaces, meetings and shared work environments.
  • Thin and lightweight build: Easier to carry between home, work and campus for people who move around regularly.
  • Long battery life: Apple rates MacBook Air models like this for up to 18 hours of video playback, helping reduce charging interruptions through the day.
  • macOS ecosystem: Works smoothly with other Apple devices for file sharing, messaging, calls and continuity features.
  • Large trackpad: Makes navigation, gesture controls and everyday multitasking feel more comfortable and precise.
  • Backlit keyboard: More comfortable for typing in low-light settings such as evening study sessions or flights.
  • Premium aluminium design: Feels sturdy and refined for daily commuting, client-facing work and long-term use.

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

A: Yes. This M3 MacBook Air can support up to two external displays when the laptop lid is closed, alongside the built-in Liquid Retina display when using one external screen. That matters if you want more desk space without moving to a MacBook Pro.

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

A: Yes, 24GB suits heavier multitasking than entry models, especially if you keep many browser tabs, large spreadsheets or creative apps open at once. It gives more headroom than 8GB or 16GB, but it is still a fanless MacBook Air rather than a Pro model.

Q: Does the MacBook Air 15-inch M3 have a fan?

A: No. The 15-inch MacBook Air with M3 uses a fanless design, so it runs quietly in normal use such as office work, streaming and study. Under long, demanding workloads, sustained performance can be lower than a MacBook Pro with active cooling.

Q: Is 512GB enough storage for this MacBook Air configuration?

A: For many buyers, yes. A 512GB SSD is a practical middle ground for documents, apps, photos and local file storage, and it gives more breathing room than 256GB. If you work with large video libraries or game files, 1TB or more is easier to manage.

Q: What ports does the 15-inch MacBook Air M3 include for everyday use?

A: This model includes MagSafe 3 charging, two Thunderbolt or USB 4 ports, and a 3.5 mm headphone jack. That covers charging, fast accessories and display connections, but many USB-A devices, HDMI monitors or SD cards will need a compatible adapter or hub.

Q: How can I check that this MacBook Air matches the model I want?

A: Check the full model description on the product page, including 15-inch size, M3 chip, 24GB unified memory, 512GB storage and Silver finish. After setup, the serial number can also be verified in macOS under About This Mac for model identification.
