Operating System Of Macbook Air


The name and version number of your Mac’s operating system appears on the “Overview” tab in the About This Mac window. If you see “macOS Big Sur” and version “11.0”, you have Big Sur. As long as it starts with “11.”, you have Big Sur installed. In the screenshot below, we have version 10.14 of macOS Mojave installed. Here’s how: From the menu bar on your Mac, select the Apple icon on the top left. Select “Software Update”. Select “Advanced”. Make sure all boxes are checked. Note: for a Mac to automatically update, it must be connected to power. Keep in mind you have a bit of control here, too. There are two ways to install Big Sur: enable automatic updates in System Preferences or download by using the following link. Or check my post with tips on installing macOS on unsupported devices. List of Apple computers compatible with macOS Big Sur. MacBook (2015 and later) MacBook Air (2013 and later) MacBook Pro (2013 and later). The MacBook Air is a line of notebook computers developed and manufactured by Apple Inc. It consists of a full-size keyboard, a machined aluminum case, and, in the more modern versions, a thin light structure. The Air was originally positioned above the previous MacBook line as a premium ultraportable.

Apple wants people to fall back in love with its latest MacBook Air.

MacbookFor many users, the pre-Retina, 13-inch MacBook Air was one of the best laptops ever made. For too long, though, it fell behind the curve as Apple introduced better performance and higher-resolution screens to the rest of its lineup. Finally, Apple brought the high-res Retina display and some other improvements to the Air in 2018. Maybe the world's best laptop was back?

2018's Air was a pretty good machine, but it wasn't a candidate for world's best laptop anymore, thanks to the prone-to-fail butterfly keyboard design and a painful lack of ports. A refresh in 2019 brought some refinements, but it didn't address either of those issues. Now, finally, Apple has pulled out the butterfly keyboard and put in something we hope will be much more dependable.

So is the 2020 MacBook Air again worthy of consideration as the world's best laptop?

Apple MacBook Air (2020)

(Ars Technica may earn compensation for sales from links on this post through affiliate programs.)
The new Air offers three CPU options. The $999 entry-level configuration has a 1.1GHz, dual-core Intel Core i3 with Turbo Boost up to 3.2GHz and a 4MB L3 cache. That's pretty anemic even for the price, but it should be powerful enough for a decent portion of the machine's target audience.

Buyers can spend an extra $100 for a 1.1GHz Core i5 with 3.5GHz Turbo Boost and a 6MB cache; if you can afford it, the cost here is worth it. There's also a 1.2GHz Core i7 with 3.8GHz Turbo Boost and 8MB cache option for $250 over the base config, but if performance is that important to you, at this price you might consider a MacBook Pro instead.


For graphics, you're looking at Intel Iris Pro graphics matching whatever CPU you pick.

In standard configurations, the Air comes with 8GB of 3733MHz LPDDR4X memory, but you can opt to upgrade to 16GB for an additional $200—which I'd recommend for a lot of people, especially if they use a bunch of non-Apple apps like, say, Google Chrome.

Storage starts at 256GB in the base config, up from 128GB in past Airs. Apple has been doubling storage across its MacBook line, and that's very welcome. 128GB was pretty tight even for light users, but 256GB is just right for those using this as a basic productivity computer. You can go up to 512GB for another $200, 1TB for another $400, or a beefy 2TB for an extra $800.

The Air has the same Retina display as before. It's a 13.3-inch IPS panel with a native resolution of 2,560 by 1,600 pixels. Apple really made HiDPI displays take off when it first introduced Retina displays, but while the company is strong on things like color accuracy, competing products now offer much higher resolutions.

The Air's screen is above the threshold beyond which more pixels make for diminishing returns, though, so its resolution isn't much of a downside. But buyers should know that the Air's display can't match the photographer-friendly color accuracy of the MacBook Pro.

This is a good time to mention that the laptop defaults to a screen area that is equivalent to 1,440 x 900, which is pretty cramped by today's standards. You can bump it higher, but it looks a bit less sharp, and UI animations (like swiping between Spaces) get just a teensy bit choppier. It's not a big deal, but it's also not ideal.

The part of the spec sheet that disappoints me most, though, is the lack of Wi-Fi 6. Instead we get the same old 802.11ac. Sure, Wi-Fi 6 is new on the scene, but you might expect to keep this computer for three or more years, and Wi-Fi 6 will probably be ubiquitous by then. Bluetooth 5.0 is present, though.

This machine also has stereo speakers, Dolby Atmos support, and a 3.5mm headphone jack, along with what seems to be the same 720p FaceTime webcam Apple has been putting in its laptops for ages. The camera is fine, but in an age of telecommuting, you wouldn't be wrong to ask for a 1080p camera at this price.

Sadly, one of the biggest problems with the 2018 and 2019 MacBook Air models persists here: only two ports, both Thunderbolt 3/USB-C. More on that in a moment.



It's refreshing to see Apple not try to 'change the world' here—but just designing a solid workstation.

The Air is thin, it has the classic tapered shape, it looks and feels sturdy, and it wastes no space or material. From an industrial design point of view, it's one of the best things Apple has ever made.

It's also slightly more repairable than it used to be, according to a recent teardown by the good people at iFixit. They found that new wiring for the trackpad allows for easier access to both the trackpad and the battery without messing with the logic board, among other things. Repairability is still not a strong suit of the MacBook Air, but it seems to be improving.

The new model is almost imperceptibly thicker than the 2019 Air, but its form is otherwise unchanged, and that's a great thing. It's still a sleek, tightly designed little laptop, which is one of the main things so many people appreciated about the Air over the years. There aren't a lot of laptops out there that feel this good to carry and to use.

The Achilles' heel of the design is the port situation, though. I'm not even talking about the fact that it uses Thunderbolt 3/USB-C; most other laptops in this class also use USB-C instead of larger USB-A ports, and it feels like that ship has sailed. I'm instead referring to the fact that it only has two ports, which may not be enough for much of the target audience, as one of those ports will usually be used for power. To make matters worse, the ports are both on the left side of the machine. Is your power outlet on the right side of your desk? Hope you're cool with running a cord across the desk or in some awkward arrangement behind it.

The ports remain the worst thing about the MacBook Air—but they're also the only thing I can criticize about the design. Now, on to the question everyone has: how is that new keyboard?
