After the site survey, we selected this location to view the eclipse. It would permit wide angle photography of totality directly above the moai, and had as good a chance as any other site on the island of clear weather. We had to shift our site a few metres to the side at the request of some seriously equipped photographers uphill of us who were recording a time-lapse sequence of the entire eclipse: glad to oblige.
| 2010-07-11 16:27 UTC |
Eclipse morning dawned beautifully, but then, as Easter Island is wont to, went all “variable”, including this downpour as we were getting ready to saddle up to head for the eclipse site.
| 2010-07-11 17:46 UTC |
But not to worry! If you don't like the weather, wait fifteen minutes! Or, in this case, shortly before we departed for the eclipse viewing site.
| 2010-07-11 19:32 UTC |
This is where we were.
| 2010-07-11 18:26 UTC |
We'd carefully plotted the course of the Sun to be above the moai at totality, so we weren't worried when the Sun was behind the palm tree just before first contact. In fact, it made for a pretty nice shot. It was windy at the start of the eclipse, but the breeze abated as totality approached.

Here is our Expedition Headquarters. The sheet, held down by the cooler and a bag is intended to image the pulsing shadow bands should they choose to appear.
| 2010-07-11 20:47 UTC |
There's nothing as cool to do during the partial phase as making cool crescent images, and Judy had made a shadow mask with “Rapa Nui” poked through a card. It worked perfectly!
| 2010-07-11 19:16 UTC |
Now we're into the partial phase. I didn't get photographs of the beginning
of the eclipse because it took a bit longer for the Sun to emerge from the
palm tree than I expected.
Toward the lower right of the Sun's limb two sunspots are visible. These
are part of the active sunspot group 1087 which, on July 9th, unleashed
a class C3
solar flare. The image at right was cropped from a
full-Sun image
captured by the
Solar and Heliospheric Observatory's
MDI Continuum instrument about an hour and a half after the eclipse. I have
rotated the north-up Sun image in the clip to correspond to the apparent
orientation of the Sun from our viewpoint in the southern hemisphere.
| 2010-07-11 19:32 UTC |
All of these detailed images of the Sun were taken with a Nikon D300 digital camera and Nikkor 500 mm catadioptric “mirror lens”, which provided the equivalent of 750 mm focal length on a 24×36 mm film camera. The same lens was used to photograph the 1999, 2001, and 2008 solar eclipses. Photographs during the partial phase were taken through an Orion metal on glass full-aperture solar filter placed before the mirror lens.

As the sliver of exposed Sun dwindled, the pulsating shadow bands became visible on the sheet we'd laid down on the sand. When they appear (which is dependent on a variety of atmospheric conditions: we saw them in Zambia and here in Easter Island, but not a hint in Iran or the Barents Sea) they are obvious to the human eye but are notoriously difficult to capture on film or video. In the 1940s, before high speed film, some argued they would always be a visual phenomenon only. Well, look at what technology hath wrought! The following video shows the shadow bands, but they're very subtle and it helps to know what you're looking for. The bands go from upper right to lower left on the sheet, and vary in intensity. At the end of the video I've added a slow motion segment which may help pick out the pulsing of the bands. When you see them yourself, there's nothing remotely subtle about the effect, so I hope that trying to dig it out of this murky video will encourage you to go and observe an eclipse with that instrument so perfectly evolved to appreciate it: the human eye.

Diamond ring! (Contemporary eclipse observers tend to call “diamond ring” way too early, tempting observers to rip off their eclipse specs prematurely and spoil their dark adaptation for totality. I'd say, keep on your eclipse specs until you see nothing but darkness, then take them off to see the spectacle in the sky.)
Anyway, here is the moment when the last part of the photosphere is being covered by the Moon. Note the hydrogen alpha red of the chromosphere and prominences along the limb of the Sun and the bead at the top of the diamond ring where the lunar profile allows a bit of the photosphere to shine through a lunar mountain valley. The arcs curving away from the Sun from the diamond ring are internal reflections in the mirror lens used to take this picture; they are not genuine effects.
In the last instants before totality, I removed the solar filter from the mirror lens on the Nikon camera and activated my pre-programmed nine stop automatic bracketing sequence. With a single press on the electronic cable release, I could take nine exposures of the eclipsed Sun ranging from a shot at 1/1000 or 1/500 second optimised for the prominences, chromosphere, and inner corona to one risking blur due to apparent motion of the Sun which would reveal outer corona streamers. This facility in the Nikon D300 is a tremendous gift to eclipse photographers: it allows capturing almost ten times as many images during totality as with manual exposures and setting of the camera, and it allows doing so without looking away from the eclipse to fiddle with dials on the camera. But if there are any eclipse chasers at Nikon headquarters reading this, there's one thing you got wrong, folks! There should be some way to set the shutter dial that both activates mirror-up and multiple exposure mode. As it stands, if you choose multiple exposure, you can shoot all nine bracketed images with one push of the remote release, but you're almost certain to lose some of the longer exposures to vibration due to mirror rebound. If you select mirror up mode, you have to push the release button eighteen times to complete the nine frame bracketed sequence, which defeats the entire purpose of auto-bracketing: speed. Please, Nikon, give us an item buried somewhere in the menus where we can activate a mode which will lock up the mirror, pause to let vibrations damp out, shoot the nine bracketed frames, and then let the mirror come back down. Eclipse photographers will sing your praises, and it should produce better material for high dynamic range images taken in less demanding circumstances.
| 2010-07-11 20:08 UTC |
An instant later, the diamond on the ring has shrunk and the corona is coming out.
| 2010-07-11 20:08 UTC |
Only instants before the photosphere is covered. The corona is revealed in all its glory. Look at those polar brushes, characteristic of an eclipse of the quiet Sun.
| 2010-07-11 21:12 UTC |
As totality enveloped us, Anakena was surrounded by the 360° twilight unique to a total eclipse of the Sun. The eclipsed Sun is out of the frame at the top of this image. The lights in the foreground are idiots trying to illuminate the eclipsed sun with the flashes on their cameras.
| 2010-07-11 20:10 UTC |
A longer exposure in mid-totality still captures the prominence at the 1 o'clock position and shows the polar brushes.
| 2010-07-11 20:09 UTC |
Going longer still, we begin to see the streamers of the outer corona.
| 2010-07-11 20:09 UTC |
And those streamers just go on and on!
| 2010-07-11 20:09 UTC |
This 1/500 second shot at mid-totality shows prominences and inner corona. The chromosphere, evident in the photos just after second contact (the start of totality) is now covered, but the prominences on the right limb remain exposed. Look at that loop prominence at the 2 o'clock position!
| 2010-07-11 20:09 UTC |
Taken at mid-totality, the eclipsed Sun is visible over the moai of Ahu Nau Nau, silhouetted against the sea. At the right stands Ahu Ature Huki with its lone moai. To the human eye, the sky was darker and the twilight shading around the horizon more prominent than in this 1/4 second exposure.
| 2010-07-11 20:10 UTC |
A longer exposure (almost) washes out the prominences, but highlights the polar brushes. Stretching colour saturation, you can see the green hue of the forbidden line of oxygen in the corona.
| 2010-07-11 20:10 UTC |
And an even longer exposure totally blows out the inner corona, but limns the extended streamers which become so obvious to the dark-adapted eye as the eclipse progresses.
| 2010-07-11 20:10 UTC |
Now we enter the domain of special effects. I've taken nine images from totality, photographed with exposures from 1/500 second to 2 seconds, manually aligned them, and assembled this high dynamic range composite image in an attempt to reproduce the visual impression of the eclipse. Bottom line: the prominences were more evident in the real thing, and the coronal streamers extended further than you can see them here. But this is much closer to what we saw in the sky than any single photographic image. Note that subtle detail of the lunar surface, illuminated by full Earthshine, is visible in this image.
| 2010-07-11 20:12 UTC |
Toward the end of totality a cloud rolled in and obscured the Sun, more or less from instant to instant. Here is an image through the cloud as prominences began to appear on the lower left limb of the Sun with the end of totality near.
| 2010-07-11 20:13 UTC |
In the last moments before the end of totality, we see the chromosphere appear through the clouds. In less than a second, the photosphere would emerge and call an end to the magic of totality—at least until the next time in the shadow!
The following video shows the approach of the Moon's shadow and totality.
It seems you're referring to macOS High Sierra 10.13.1 (the actual version number is 10.13.1, not 10131).
Here’s a sample post discussing that .dmg file from a retrospective / tech enthusiast perspective:
Title: Revisiting macOS High Sierra 10.13.1 – A Look Back at That Classic .dmg Installer
Post:
Let’s take a quick trip down memory lane to late 2017. macOS High Sierra 10.13.1 (build 17B1002) wasn’t the flashiest update, but for those of us who still have that original InstallMacOSX.dmg or the macOSHighSierra10.13.1.dmg sitting in our Downloads folder, it brings back a specific era of stability and transition.
What made 10.13.1 special?
The .dmg experience
Back then, installing from a .dmg meant mounting it, running the installer, and waiting through that dreaded “Estimating time remaining…” – but for many admins and tinkerers, keeping a local .dmg of 10.13.1 was essential for creating USB boot drives or downgrading from buggy 10.13.2 betas.
Is it still useful today?
Not really – Apple no longer signs 10.13.x for clean installs (except with old Macs that support it). But if you find that old macOSHighSierra10.13.1.dmg in your backups, it’s a neat digital artifact. Just don’t run it on modern hardware unless you enjoy chasing missing security patches.
Final thought:
High Sierra felt like Apple’s “under-the-hood” cleanup before Mojave’s dark mode hype. 10.13.1 was the first patch that made it usable.
Anyone else still have old macOS .dmg files saved for nostalgia? Share yours below. 🖥️💾
If you meant a different .dmg (e.g., an unofficial patcher or a specific bundle), let me know and I can adjust the tone and details.
Released on October 31, 2017, macOS High Sierra 10.13.1 was the first major update to the High Sierra operating system. While newer versions like 10.13.6 eventually followed, this specific release remains a common target for those restoring older hardware or seeking compatibility with mid-2017 software environments.

Understanding macOS High Sierra 10.13.1 DMG: Features, Compatibility, and Installation
macOS High Sierra 10.13.1 was released on October 31, 2017, as the first major update to the High Sierra operating system. While the broader High Sierra release focused on refining the core technologies of its predecessor, macOS Sierra, version 10.13.1 brought specific user-facing additions and critical security patches. Key Features and Updates in 10.13.1
The 10.13.1 update introduced several refinements beyond the initial 10.13 release:
New Emoji: Over 70 new emoji characters were added, including new food types, animals, and more expressive smiley faces.
Security Patches: A vital fix for the KRACK (Key Reinstallation Attack) Wi-Fi vulnerability was included to protect users on public networks.
Enterprise Improvements: Improved reliability for SMB printing and accessibility of Touch ID preferences for mobile users on MacBook Pro models with a Touch Bar.
APFS Refinements: Support for unlocking FileVault-encrypted APFS volumes using a recovery keychain file. Core Technologies of High Sierra
As part of the High Sierra family, the 10.13.1 version utilizes several foundational technologies: It seems you're referring to macOS High Sierra 10
Apple File System (APFS): Replaced the older HFS+ system, offering enhanced performance, security, and reliability for SSD-based Macs.
High Efficiency Video Coding (HEVC): Also known as H.265, this standard allows for 4K video that is up to 40% smaller than previous standards.
Metal 2: Apple's advanced graphics technology that improved GPU performance and added support for external GPUs (eGPUs) and VR content creation. System Requirements and Compatibility
To run macOS High Sierra 10.13.1, your Mac must meet these minimum hardware specifications: Memory: At least 2GB of RAM.

Diving Into macOS High Sierra 10.13.1 While it might feel like a blast from the past, macOS High Sierra 10.13.1 remains a critical milestone for legacy Mac users. Released in October 2017, this update wasn't just about adding new emoji—though it did add 70 of them [23]. It was a refined "maintenance" release that followed the pattern of "Snow Leopard" by focusing on foundational stability and "under-the-hood" improvements [11, 14]. Why 10.13.1 Matters
If you are hunting for a 10.13.1 DMG, you are likely maintaining a vintage machine or building a virtual environment. Here is why this specific version is noteworthy:
APFS Transition: High Sierra introduced the Apple File System (APFS), which optimized storage for SSDs with features like "Instant Cloning" [15, 24].
The "Root" Security Patch: Shortly after its launch, 10.13.1 became famous for a critical security flaw that allowed "root" access without a password. Apple quickly issued a Security Update to patch this, making it essential for anyone on this version to double-check their security status [12].
Fixes & Enhancements: It improved the reliability of Microsoft Exchange sync in Mail and resolved issues where Bluetooth appeared unavailable during Apple Pay transactions [23]. Finding and Using the DMG
Getting your hands on an official DMG can be tricky today since Apple officially ended support for High Sierra in early 2021 [30].
Official Sources: While direct DMG links are rare on modern Apple Support pages, you can often still access the Mac App Store link for High Sierra if your hardware supports it [33].
Creating a Bootable USB: Once you have the installer, the standard way to create media is through the Terminal createinstallmedia command. This is vital for clean installs on older 2010–2011 MacBooks where High Sierra is the end-of-the-line OS [2, 10].
Third-Party Caution: Be extremely careful downloading DMGs from unofficial blogs or forums. Always verify the checksums if possible to avoid security risks [5]. Is it still usable in 2026?
High Sierra is now several years past its final security update [30]. It is considered "End of Life" and lacks modern browser support for many websites [37]. If you're using it for work or financial tasks, it's a significant security risk [2, 5]. However, for a dedicated music production rig or a legacy gaming machine, it "absolutely screams" on older hardware due to the Metal 2 graphics API [17].
Downloading macOS High Sierra 10.13.1 specifically as a DMG can be tricky because Apple primarily distributes full installers as .app files through the Mac App Store. Official Download Method
Apple does not provide a direct DMG for the full 10.13.1 installer. Instead, you can download the latest version of High Sierra (10.13.6) using the official Mac App Store link.
Requirements: Your Mac must be compatible with High Sierra to download it this way.
Browser: Use Safari to open the link, as other browsers may fail to redirect to the App Store properly. How to Get a DMG File
If you specifically need a .dmg (e.g., for creating a bootable USB on Windows or for a virtual machine), you have two main options:
Create Your Own: Download the .app installer from the App Store on a compatible Mac, then use Terminal commands to convert the installer into a bootable DMG.
Use Third-Party Tools: Utilities like Mist can download macOS installers and firmwares directly from Apple's servers and package them into DMG or ISO formats for you.
Patchers: Tools like the macOS High Sierra Patcher allow you to download a complete "Install macOS High Sierra.app" even on unsupported hardware, which you can then use to create your own disk image. Important Notes
Security: High Sierra reached its "End of Life" in January 2021. It no longer receives security updates, so use it with caution for online tasks.
Specific Version: Apple typically only offers the latest point release (10.13.6). If you need exactly 10.13.1 for testing, you may need to find archived versions on sites like the Internet Archive, though these are not official Apple sources. Using macOS High Sierra in 2025

How I Downloaded macOS High Sierra in 2026 (Even on Older Macs)
It was a typical Monday morning at Apple HQ in Cupertino. The sun was shining bright, casting a warm glow over the sleek, modern campus. Engineers and developers were buzzing around, sipping their coffee and preparing for another day of innovation.
In a small conference room, a team of experts had gathered to discuss the latest update to their beloved operating system, macOS. The topic of conversation was the recently released macOS High Sierra 10.13.1, and specifically, the DMG (Disk Image) file that contained the installation package.
One of the engineers, a brilliant and meticulous individual named Alex, stood at the whiteboard, marker in hand. "Alright, team, let's review the changes in 10.13.1," Alex began. "We've got improved stability, security patches, and some exciting new features like the ability to capture and edit HEIF photos."
As Alex highlighted key points, the team discussed the benefits and challenges of creating a seamless installation experience for users. Their goal was to ensure that the DMG file for macOS High Sierra 10.13.1 was not only efficient but also easy to use.
Suddenly, a team member, Rachel, spoke up. "Hey, has anyone noticed the file size of this DMG? It's massive!" The team chuckled, knowing that large file sizes could be a pain for users with slower internet connections.
The conversation turned to optimizing the DMG file for faster downloads and more efficient installations. The team brainstormed ideas, from compressing files to streamlining the installation process.
Just then, their manager, Michael, walked into the room. "How's it going, team? Any updates on the 10.13.1 DMG?" Alex filled him in on their discussion, and Michael nodded thoughtfully.
"Great work, everyone. Remember, our users expect a smooth, hassle-free experience. Let's make sure this DMG meets those expectations." With renewed focus, the team dove back into their work, driven to perfect the macOS High Sierra 10.13.1 installation package.
As the day progressed, their hard work paid off. The DMG file was optimized, and the installation process was streamlined. The team felt a sense of accomplishment, knowing that their efforts would soon benefit millions of Mac users worldwide.
And so, the macOS High Sierra 10.13.1 DMG was born – a testament to the dedication and expertise of the Apple team. Its release marked a significant milestone in the evolution of macOS, providing a solid foundation for future innovations and a seamless user experience.

It is the final stop on the line for a massive era of Mac software history.
