In short

Get a MacBook Air 15-inch (M3) with 16GB of memory, not 8GB, and only at a clear discount from its $1,299 launch price. You still get a 15.3-inch, 500-nit screen, six speakers, Wi-Fi 6E and up to 18 hours of video playback, but the camera is 1080p. The 15-inch M4 added a 12MP Center Stage camera and two external displays with the lid open, and the M5 starts at 512GB with Wi-Fi 7.

Who it is for

  • Buyers who want a 15-inch, fanless Mac for less and can find a 16GB model at a fair price.
  • 15-inch M2 owners who need Wi-Fi 6E, or a second monitor and don't mind closing the lid to use it.
  • 13-inch M3 owners who want more room: a 15.3-inch screen and six speakers instead of four.

Who should skip it

  • Anyone shopping new. The current 15-inch M5 starts at 512GB, goes to 4TB and has Apple's N1 chip with Wi-Fi 7.
  • Frequent video callers. The camera is 1080p FaceTime HD; the 15-inch M4 moved to a 12MP Center Stage camera.
  • Anyone who wants two monitors with the lid open. The M3 runs one at up to 6K, and a second at up to 5K only once you close the lid.
  • Commuters who want less weight. The 13-inch M3 weighs 1.24 kg (2.7 pounds) to this one's 1.51 kg, with a 52.6Wh battery and four speakers.

What sets it apart

  • A 10-core GPU in every 15-inch M3; the 13-inch M3 starts at 8 GPU cores.
  • Wi-Fi 6E and Bluetooth 5.3, a step up from the 15-inch M2's Wi-Fi 6.
  • A 66.5Wh battery that Apple rates for 15 hours of web browsing and 18 hours of Apple TV app playback.
  • Six speakers with force-cancelling woofers, playing Spatial Audio with Dolby Atmos.

Caveats

  • Fast charging needs the 70W USB-C adapter, which was an option at purchase. The box has the 35W Dual USB-C Port Compact Power Adapter.
  • Apple hasn't announced an end date for macOS support on this model, so check its current compatibility list before you buy.

When Apple announced the 15-inch M3 on 4 March 2024 at $1,299, its gains over the M2 were Wi-Fi 6E and a second external display with the lid closed. It reached stores on 8 March 2024. What it didn’t get is the 12MP camera and the lid-open dual-display support that came a generation later.

What the 15-inch M4 and M5 changed

  • The 15-inch M4 made 16GB of memory standard, replaced the 1080p camera with a 12MP Center Stage camera, runs two external displays with the lid open and added a sky blue finish.
  • The 15-inch M5 starts at 512GB of storage and goes to 4TB, uses Apple’s N1 chip for Wi-Fi 7, and comes with a 40W Dynamic Power Adapter.

If you own a 16GB M3 and one external monitor is enough, keep it. The M4 is the upgrade for video calls and for two monitors with the lid open; the M5 is the one for more storage and Wi-Fi 7.

Screen, sound and battery

The 15.3-inch Liquid Retina screen has 2880 × 1864 pixels at 224 ppi, 500 nits, P3 wide color and True Tone. It isn’t a touchscreen, and there’s no ProMotion. Six speakers with force-cancelling woofers play Spatial Audio with Dolby Atmos, and three beamforming microphones support Voice Isolation and Wide Spectrum modes.

Apple’s figures for the 66.5Wh battery are 18 hours of movie playback in the Apple TV app and 15 hours of wireless web, measured in January 2024 on an 8GB, 256GB model. The box has the 35W Dual USB-C Port Compact Power Adapter and a 2-meter USB-C to MagSafe 3 cable.

Ports and displays

You get MagSafe 3, a 3.5 mm headphone jack and two USB-C ports that handle Thunderbolt 3 and USB 4 at up to 40Gb/s, DisplayPort and charging. You can run one external display at up to 6K and 60Hz alongside the laptop’s own screen. A second one, at up to 5K and 60Hz, works only with the lid shut, which suits a laptop parked on a stand but not one you type on.

Price

Apple’s US launch price was $1,299, or $1,199 with education pricing. It’s no longer Apple’s current 15-inch Air, so you’ll be buying it used, refurbished or through education stores, where prices vary. Compare whatever you’re offered with a new 15-inch M5 before you decide.

Frequently asked questions

Should I buy a 15-inch M3 with 8GB or 16GB?

16GB if you can find it. The memory is soldered, so an 8GB machine stays at 8GB, and Apple made 16GB the standard amount on the 15-inch M4.

Does the 15-inch M3 have Thunderbolt 4?

No. Its two USB-C ports support Thunderbolt 3 and USB 4 at up to 40Gb/s, plus DisplayPort and charging. Apple lists Thunderbolt 4 only on later Airs.

Does the 15-inch M3 come in sky blue?

No. It comes in silver, starlight, space gray and midnight. Sky blue arrived with the 15-inch M4.

Does the 15-inch M3 run Apple Intelligence?

Yes. Apple supports Apple Intelligence on Macs with M1 or later, and the M3 qualifies.
