Apple no longer sells the M1 MacBook Air as of earlier this month, discontinuing it and offering the M2 version of the Air as its entry-level model instead. But it looks like the M1 Air may live on, at least for a while—US retailer Walmart made a point of announcing today that it would carry and sell the M1 Air in its online store and at “select” retail locations for a much-lowered price of $699 .

This is lower than the $999 that Apple was asking for the laptop just a few weeks ago, and it's lower than the $759 that the M1 Air goes for in Apple’s refurbished store . These prices are all for the base configuration of the M1 Air, with 8GB of memory and 256GB of storage. Walmart offers all three color finishes for the M1 Air—silver, gold, and space gray—but doesn’t directly sell any versions with more RAM or storage.

This isn’t the Air config we’d recommend to most enthusiasts—for them, an M3 Air or a refurbished M2 model with more RAM and storage come with enough benefits to be worth the extra cost. But it is a surprisingly low price for what remains a solid entry-level laptop, especially given that Walmart doesn’t offer any other Macs in its stores (other Macs on Walmart’s website are available from third-party sellers).

When Apple upgraded its Macs with the M2 chip, some users noticed that storage speeds were actually quite a bit lower than they were in the M1 versions. Both the 256GB M2 MacBook Air and the 512GB M2 MacBook Pro had their storage speeds roughly halved compared to M1 Macs with the same storage capacities.

Teardowns revealed that this was because Apple was using fewer physical flash memory chips to provide the same amount of storage. Modern SSDs achieve their high speeds partly by reading from and writing to multiple NAND flash chips simultaneously, a process called "interleaving." When there's only one flash chip to access, speeds go down.

Early teardowns of the M3 MacBook Air suggest that Apple may have reversed course here, at least for some Airs. The Max Tech YouTube channel took a 256GB M3 Air apart, showing a pair of 128GB NAND flash chips rather than the single 256GB chip that the M2 Air used. BlackMagic Disk Speed Test performance increases accordingly; read and write speeds for the 256GB M2 Air come in at around 1,600 MB/s, while the M3 Air has read speeds of roughly 2,900 MB/s and write speeds of about 2,100 MB/s. That's roughly in line with the M1 Air's performance.

Right off the bat, the M3 MacBook Airs aren't as interesting as the M2 models.

July 2022's M2 MacBook Air updated the design of the 13-inch laptop for the Apple Silicon era after the M1 Air's external design played it safe. And the first-ever 15-inch MacBook Air , released over a year later, was an appealing option for people who wanted a larger screen but didn't need the extra power or cost of a MacBook Pro. Together, they were a comprehensive rethink of Apple's approach to its mainstream laptops, modeled after the similarly dramatic Apple Silicon MacBook Pro redesigns .

The M3 Airs don't do any of that. They are laptop designs we've already seen, wrapped around a processor we've already seen. But they may end up being more important than the M2 Airs because of when they're being released—as the last of the Intel Macs slowly age and break and Apple winds down software support for them (if not in this year's macOS release, then almost certainly next year's). Between the faster chip and a couple of other feature updates, the new machines may also be the first ones that are truly worth a look for M1 Air early adopters who want an upgrade.

One longstanding limitation of Apple's most basic Mac chips—the no-adjective M1, M2, and M3—has been their inability to work with more than a single external monitor at a time. This was one of the only ways in which the Apple Silicon era has been a step back from the Intel era, where most Macs supported at least two external displays, plus the screen built into the MacBook Air or Pro you were using. (Would an integrated Intel GPU actually work well with that many screens connected? Usually not. But at least you could try .)

When Apple launched the M3 version of the MacBook Pro last fall, the one-external-display limitation was still in place. But today's announcement of the M3 MacBook Air came with a small but pleasant surprise for anyone who wants their Mac to do double-duty as a laptop and a desktop—if the laptop's lid is closed, the M3 can now run a pair of external displays over its Thunderbolt ports. And Apple confirmed to 9to5Mac that the 14-inch M3 MacBook Pro would have the same functionality enabled via a future macOS update (we've asked Apple to verify whether it's coming in the imminent macOS 14.4 update or at some future date).

Apple's spec sheets say that the M3 can drive one 6K display at 60 Hz and one additional 5K display at 60 Hz when your laptop's lid is closed. The M3 MacBook Pro's spec sheet still hasn't been updated as of this writing, but we would expect it to be at some point after the relevant software update is released.

Apple has quietly refreshed its MacBook Air lineup , bringing new chips (and in some cases, new prices) to its most popular laptops. New 13- and 15-inch MacBook Airs include Apple's latest-generation M3 chip, while the old M2 MacBook Air now replaces 2020's M1 MacBook Air as Apple's $999 entry-level laptop. The new 13- and 15-inch M3 systems start at $1,099 and $1,299; they can be ordered today and will be released on March 8th.

The new Airs use the same design as the M2 versions. Compared to older M1 and late-Intel-era Airs, they have slightly larger displays with a prominent notch, a non-tapered but still thin-and-light chassis, larger trackpads, modestly refined keyboards, and a MagSafe port for charging.

All of the new Airs use the M3, with no options to upgrade to faster or more capable processors (frustratingly, this means the Air is still restricted to just a single external display). The $1,099 13-inch Air does use a slightly cut-down version of the chip with 8 GPU cores instead of 10, with the 10-core GPU available as a $100 upgrade; all 15-inch models use the fully enabled M3 with the 10-core GPU.
