That honor goes to Apples most powerful laptop, the MacBook Pro, which was updated with the M4 chip last October. The MacBook Air traditionally gets the chip update a few months afterward and right on schedule, the Airs time has come for its M4 update.The MacBook Air is a great laptop with an M4 or even with the older M3 chip. But even with the four major changes in the M4 MacBook Air, only one of them is a compelling reason to ditch an M3 MacBook Air that you recently bought. And if youre still relying on an Intel-based MacBook Air, the M4 MacBook Air is an offer you cant refuseit has performance that will save you a significant amount of time.15-inch M4 MacBook Air: Our models specificationsApple offers three standard configurations each for the 13- and 15-inch MacBook Air. The 15-inch MacBook Air in this review is customized with more RAM and storage than the top-end standard configuration, which starts at 16GB of RAM and 256GB of storage. Here are the specs for our review unit:CPU: 10-core M4 (4 performance cores, 6 efficiency cores)GPU: 10-core M4Neural engine: 16-coreMemory: 16GB unified memory (120GBps memory bandwidth)Storage: 512TB SSDDisplay: 15.3-inch Liquid Retina LED backlit display with IPS; 2880-by-1864 native resolution at 224 pixels per inch; 500 nits brightness; P3 color; True TonePorts: 2 Thunderbolt 4/USB-C; MagSafe 3; 3.5mm audioNetworking: Wi-Fi 6E (802.11ax); Bluetooth 5.3Weight: 3.3 pounds (1.51 kg)Dimensions: 0.45 by 13.40 by 9.35 inches (1.15 by 34.04 by 23.76 centimeters)Battery capacity: 66.5WhPrice (as tested): $1,399/1,399/CA$1,999/AU$2,399The new Sky Blue option for the MacBook Air replaces the Space Gray color.Foundry15-inch M4 MacBook Air: PerformanceThe new MacBook Air spotlights its new M4 chip, which has a 10-core CPU (4 performance cores, 6 efficiency cores), 8-core or 10-core GPU, and a 16-core Neural Engine. Compared to the M3 it replaced, the M4 has two more efficiency cores, two more GPU cores, and general CPU tweaks to make it a better performer.Geekbench 6.4Results are expressed as Geekbench scores. Higher scores/longer bars are faster.Our performance analysis starts with Geekbench 6 for a general, overall view. In both the Single-Core and Multi-Core tests, the M4 MacBook Air was 23 percent faster than the M3 MacBook Air. Thats along the lines of what we usually get from one chip generation to another.The older the chip, the better the performance comparison gets with the M4. The M4 offers a 46 percent boost over the M2 MacBook Air; if you have an M2 Air, that boost is attractive, but you might shrug and decide you dont need to upgrade. If you have a M1 MacBook Air, however, the M4 upgrade is a lot more attractive from a pure performance perspective.If you have an Intel MacBook Air, well, Ive urged you to upgrade to an M-series Air since the M2, but I understand if youve hedged then, even with the M3. But upgrading to an M4 will being substantial time savings no matter what youre doing.Apples trackpad has long been a strength of its MacBook lineup.FoundryCinebench 2024Results are expressed as Cinebench scores. Higher scores/longer bars are faster.Cinebench 2024 is a test that performs 3D rendering. Most people who do the kind of work tested by Cinebench are using a higher-need MacBook Pro, but the MacBook Air is up to the task. Again, as we saw with Geekbench, the results show an solid incremental 21 percent boost from the M3 to the M4.HandBrake 1.9.2 video encodeResults are times in seconds. Lower times/shorter bars are faster.We used HandBrake to encode the Tears of Steel video from 4K to a 1080p H.265 file. When doing the encoding completely in software using the H.265 (x265) video encoder, the M4 is a healthy 31 percent faster than the M3. When using the available hardware acceleration through HandBrakes H.265 (VideoToolBox) encoder, the M4 was 40 percent faster.iMovie 4K video exportsResults are times in seconds. Lower times/shorter bars are faster.We exported a 10-minute 4K video at two settings in iMovie to gauge CPU performance. The M4 was 16 percent faster than the M3 when exporting the file using the ProRes codec. When we changed the quality setting of the export to High, the M4 advantage shrank to 6 percent.Blackmagic Disk TestResults are megabytes per second. Higher rates/longer bars are faster.The SSD results between the M3 and M4 MacBook Air are practically the same. Theres a little boost from the M2 to the M4, but you need to do long, sustained disk reads and writes to tell the difference.With the M1 and M2 MacBook Air with 256GB of storage, Apple used a single 256GB SSD chip, which adversely affected performance. The company changed that to a pair of 128GB SSD chips in the M3 MacBook Air, which improved performance. Our review unit has a 512GB SSD (presumably installed as multiple SSD chips), so we cant verify the performance of the laptop with a 256GB SSD, but it would seem unwise for Apple to go back to its old ways. We dont think you need to worry if youre eyeing an Air with a 256GB SSD.Geekbench 6 ComputeResults are expressed as Geekbench scores. Higher scores/longer bars are faster.Geekbenchs Compute benchmark tests GPU performance using Metal or OpenCL APIs. If a game has been written natively for the Mac, it should be using the Metal API for the best performance. The M4 MacBook Air offers a 16 percent boost over the M3both of these chips have a 10-core GPU, so Apple has improved the M4s GPU.Videogame frame ratesResults are frames per second. Higher rates/longer bars are faster.Testing was done using the built-in benchmarks for Borderlands 3, Total War: Warhammer III, and Civilization VI.Game Mode for macOS automatically activates when a game launches to optimize performance.Geekbench AIResults are expressed as Geekbench scores. Higher scores/longer bars are faster.Apple Intelligence is a major marketing message from Apple. Whether youre using the AI-based features or not, theyre part of Apple promotions going forward. Apple Intelligence started to appear in macOS Sequoia 15.1 and more features will be delivered over time.Geekbench offers an AI benchmark that checks the performance of Apple Neural Engine in its chips. But the way Apple Intelligence is implemented now doesnt feel super processor intensive so youre not going to feel a difference in say, using Image Playground on an M4 than on an M1.15-inch M4 MacBook Air: Ports, external display support, and connectivityApple still provides two USB Type-C ports on the M4 MacBook Air, but theyve been upgraded from Thunderbolt 3 to Thunderbolt 4. This leads to the most compelling reason to upgrade from an M3 or older Air: the M4 Air can run up to two external displays at 6k resolution and 60Hz. Thats in addition to the laptop display, so theres no more clamshell compromise as was with the M3 Air. Thats a big deal for a lot of users who bought a MacBook Pro instead or turned to an external hub solution.Other than the better display support, users arent going to notice much of a difference between Thunderbolt 3 and 4. As usual, the Thunderbolt ports are also USB-C ports and these ports support the USB 4 specification, thus Apple calls them Thunderbolt/USB 4 ports.If you want, you can connect two 6K/60Hz displays to the MacBook Airs Thunderbolt/USB 4 ports, and still be able to use the laptops display.FoundryThe M4 MacBook Air uses Wi-Fi 6E (802.11ax) and Bluetooth 5.3 for wireless connectivity. Apple has not commented on why it didnt upgrade to Wi-Fi 7 like it did with the iPhone 16, but its nothing to be concerned about. You need to be connecting to Wi-Fi 7 hotspots to take advantage of the faster speed, and theyre not readily available right now.15-inch M4 MacBook Air: CameraThe M4 MacBook Air drops the aging 1080p FaceTime camera for something more modern: a 12MP Center Stage camera. Its the same camera that Apple offers in the MacBook Pro, and it has much-improved image quality. Center Stage is a boon, too; I only realized recently how much I shift around while recording the Macworld Podcast (excuse me for the plug), and Center Stage helps make sure Im centered in the frame, which matters when youre in a video with multiple users. Video conferences are now the norm, so having a high-quality camera in the MacBook Air is a great and necessary feature.The 12MP camera on the Mac has been a long time coming. It was only four years ago that Apple introduced the 1080p camera to replace the 720p one starting with the iMac, while in the meantime, the 12MP front-facing camera has been on the iPhone since the iPhone 11 in 2019. So yeah, finally. (That also means longtime readers of Macworld can now stop hearing us harp about the Mac cameras. At least until 12MP becomes pass.)15-inch M4 MacBook Air: Battery life & chargingThe M4 MacBook Air has the same battery as before: a 66.5-watt-hour lithium polymer battery that Apple says offers 15 hours of wireless web and 18 hours of video streaming.Battery lifeResults are times in minutes. Longer bars/higher results are better.Our battery life test involved playing a loop of the 4K Tears of Steel video with the display set at 150 nits. The new laptop didnt last quite as long as the M2 and M3 MacBook Airs, but it still took nearly 18 hours to drain its battery. While using the M4 Air for work all day (mostly to write this review), I never had a concern for battery life and didnt need to plug it in until I was done for the day.The included 35W power adapter has two USB-C ports, so you can plug in another device and charge it along with the Air. Apple includes a braided MagSafe cable that is color-matched to the laptop.Apple includes a high-quality color-matched braided MagSafe cable and a 35-watt power adapter with two USB-C ports.Foundry15-inch M4 MacBook Air: Enter Sky Blue, exit Space GrayApple introduces a new Sky Blue color that replaces Space Gray. It almost feels like Apple introduced Sky Blue and dropped Space Gray to emphasize the color scheme it does with consumer-level products, which are offered in a rainbow of colors.Sky Blue is lighter than the Blue iMac (the one I reviewed last November) and its a nice shade that looks fine on a laptop. Its not the same as Ultramarine on the iPhone 16, but its close enough if youre into coordinating your Apple device colors.How a Silver MacBook Pro (left) compares to the Sky Blue MacBook Air.FoundryIf you want a darker MacBook Air, your only choice now is Midnight. I cant say Im going to miss Space Gray, but I didnt hate it, either. It varied in tone over the years, and I preferred it in darker shades. Apple will probably bring it back someday; maybe theyll spell it as Grey to give it new life.15-inch M4 MacBook Air: What didnt changeThis review focuses on what Apple changed from the M3 to the M4 MacBook Air. The following components did not change but should be mentioned since they do play a role in your buying decision. Ive included links to our original posts, in case youre interested in more detail.Design: Apple introduced this design with the M2 MacBook Air. Learn more.Display: The Liquid Retina (LED) display still looks great. Learn more.Keyboard and trackpad: Other than the mute icon, which gets a slash on the M4 MacBook Air, the keyboard is the same Magic Keyboard introduced with the last Intel model in 2020 and updated with the M2 redesign. Learn more.The Mute icon makes a comeback with the M4 MacBook Air.FoundryShould you buy the 15-inch M4 MacBook Air?In my M3 MacBook Air review last year, I said it was the best laptop choice for just about anyone. With the M4 MacBook Air, that holds, but this laptop is better. The M3 Airs clamshell compromise with the external display support was a deal killer for a lot of users. So, the M4 Airs expanded external display support is a more important upgrade than the performance improvements. Dont get me wrong, thoughfaster is always better. The 12MP Center Stage camera is an overdue upgrade that makes Apples general consumer laptop feel more professional.Its also cheaper by $100 across the board. The model we tested that sells for $1,399 would have been $1,499 for the same specs with an M3 chip. Thats a nice and surprising discount, especially considering you get twice the RAM you got when the M3 launched in March 2024.That all being said, if you have an M3 or M2 MacBook Air in a production environment and its external display support is a major hindrance to your productivity, then this is a no-brainer upgrade. But if thats not the case, then its also likely that you are not doing the type of work where the speed difference would have a noticeable effect. The MacBook Air you have will capably serve you for years to come.FoundryIf you have an M1 MacBook Air, well, thats when this M4 model looks very appealing. The M4 Air isnt just about a faster chip, its also a fresh design, an upgrade from a 720p FaceTime camera, and better external display support. Plus, the M1 Air was available only in a 13-inch design, and now theres also a 15-inch model available. So theres a lot more here to enjoy if you decide to upgrade.And finally, my recommendation to Intel-based MacBook Air owners is the same as with the M3 MacBook Air: Make the investment. Even if you need an Intel machine becuse youre relying on some tool or software that isnt Apple silicon-compatible, you need to rectify that situation because you are hindering your productivity. Make the change. You wont regret it.
