Diminishing Returns Mac OS

Longer keys provide greater security however there is diminishing returns as key length increases. Also, increasing the key length also increases computational costs exponentially (by the cube of the change, so 2048 is 8x more demanding than 1024-bit). Diminishing returns when you get over £100. Comfort and the ability to be connected to more than one device across different OS. Apple's custom next-generation Mac processor entered mass. I see this as more of a reflection of the relative maturity and sophistication of Mac OS X than a problem with Apple. We're reaching a point of diminishing returns. 20 years of Mac OS X ※ 20 years of macOS as we know it today. It was the reason I returned to the Mac after a post-NeXT stint of Windows (mostly NT), and is still the reason I use Apple hardware at home. An instruction passed along in RISC takes less energy to compute, and can be understood by a smaller, less advanced chip. Those are all big advantages but unfortunately, they have diminishing.

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

For 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?

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.

Beat virus mac os. 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.

Design

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?

These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

What you need to create a bootable installer

• A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
• A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

• Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
  These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
• Download: OS X El Capitan
  This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

1. Connect the USB flash drive or other volume that you're using for the bootable installer.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.

After typing the command: Bank heist noir mac os.

1. Press Return to enter the command.
2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
   

Use the bootable installer

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

1. Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
2. Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes.
3. Select the volume containing the bootable installer, then click Continue.
4. When the macOS installer opens, follow the onscreen instructions.

A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.

For information about the createinstallmedia command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:
