A Little Mac History: Naming OS Versions
Versions of macOS have had both public and private internal code names since OS X was released as a beta version for $29.95 on September 13, 2000. This makes it easier than saying “I am running macOS 10.13.2.” They started naming the operating system (OS) with names of big cats until 2013, when they switched to names of locations in Apple’s home state of California, likely because they were running out of large members of the feline species.
The first Mac OS X Public Beta was internally code named “Kodiak.”

macOS High Sierra
macOS High Sierra (version 10.13) is the fourteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. The successor to macOS Sierra, it was announced at the WWDC 2017 on June 5, 2017. It was released to the public on September 25, 2017. The name "High Sierra" refers to the High Sierra region in California. As with Snow Leopard, Mountain Lion and El Capitan, the name also alludes to its status as a refinement of its predecessor, focused on performance improvements and technical updates rather than user features.

High Sierra New File System: APFS
APFS (Apple File System) is Apple’s new and modern file system that was introduced in macOS 10.13 (A.K.A. macOS High Sierra). It is a replacement for HFS+ (Hierarchical File System Plus) which has been around since 1998 and came out when the first iMac appeared, which in turn was preceded by HFS (Hierarchical File System) which appeared in 1985 when the Mac Plus appeared, and MFS (Macintosh File System) which appeared in 1984 alongside the original Macintosh. APFS is meant to be the default file system for all Apple products. In fact, if you’ve got an iPad or an iPhone, you’ve been running APFS since March 2017 when it was introduced as part of the iOS 10.3 update, and you likely didn’t know about it. Even the Apple Watch runs APFS as its file system.
High Sierra New File System: APFS
Apple File System (APFS) is a proprietary file system for macOS, iOS, tvOS and watchOS, developed and deployed by Apple Inc. It aims to fix core problems of HFS+ (also called Mac OS Extended), APFS's predecessor on these operating systems. Apple File System is optimized for flash and solid-state drive storage, with a primary focus on encryption. Apple File System was announced at Apple's developers conference (WWDC) in June 2016 as a replacement for HFS+, which had been in use since 1998. It was released for iOS devices on March 27, 2017, with the release of iOS 10.3 (and you likely didn’t notice it!) and for macOS devices on September 25, 2017, with the release of macOS 10.13, High Sierra.
64-bit node number support An inode is a data structure used to represent a file system object like a file or a directory, with each inode storing the attributes and disk block location(s) of the file system object’s data. These attributes can include object manipulation metadata like change, access or modify time, and owner and permission data. 64 bits can represent up to 18,446,744,073,709,551,615 (quintillion) objects, so Apple’s definitely looking at the future of big storage with APFS. By comparison, HFS+ can only address up to 4,294,967,295 (trillion) objects.
High Sierra New File System: APFS
High Sierra
Support for nanosecond time stamp granularity File systems create a log of writes. HFS+ timestamps are only accurate to one second; that’s known as the granularity of the timestamps. APFS can track those timestamps with a granularity of one nanosecond — that’s one billionth of a second. This results in much better recovery from power-loss situations.
High Sierra
Crash protection While APFS is writing data to a storage device, it makes a copy of metadata that describes the attributes of a file or folder. In the case of a power loss or severe system crash while the file system is writing to storage, crash protection ensures that what APFS writes to storage and writes to the the file system journal are completely synchronized
High SierraSparse file support Sparse files are not supported by HFS+, and that’s not good. A sparse file is a computer file that tries to use file system space more efficiently when a file is mostly empty. With sparse files, storage is only allocated when needed, so large files can be created even if there’s insufficient free space available. APFS, like other modern file systems (many forms of Unix and NTFS), supports sparse files.

High SierraEncryption improvements Mac encryption can be done several ways right now; through File Vault for full-disk encryption or through third-party applications for per-file encryption. APFS allows native encryption scalable to individual files depending on the level of security you desire. A file or directory can have no encryption, single-key encryption, and “multi-key encryption with per-key files and another key for sensitive metadata”. Since all Apple devices — not just the Mac — will base storage of data on APFS in the future, they’ll all have the option of providing encryption to files.
Fast directory sizing Back in the days of slower (PowerPC-based) Macs, getting a read on the amount of available disk space could take a while; doing a “Get Info” on a volume could take minutes while the Mac did stat calls to get an answer on just how much space was being used. Faster Macs have made that wait a lot shorter (seconds with a fast Mac), but APFS fast directory sizing will be almost instantaneous. The new file system gives macOS a method of querying the size of a directory and its child objects very quickly.
New Hardware: Touch
iOS devices are primarily touch devices, and in the past, Apple has said touch is not something they would develop for the Mac platform.
New Hardware: Touch
Until the Touch Bar.
New Hardware: Touch
The Touch Bar replaces the row of function keys on new MacBook Pros that have the Touch Bar. The OLED screen that is the Touch Bar is powered by an ARM processor , like those that power iOS devices. The ARM chip creates the icons that appear in the Touch Bar.
New Hardware: Touch
The Touch Bar also supports Touch ID, just like modern iOS devices. This includes the ability to use Apple Pay right on your MacBook, as well as authentication for logging in multiple users.

Apple Pay on the web
New Hardware: Touch
How to use Apple Pay with the Touch Bar 1 Open Safari on your MacBook. 2 Navigate to a participating retailer website that offers Apple Pay on the web. 3 Navigate through to the checkout process. 4 Tap Checkout with Apple Pay. 5 Tap Buy with Apple Pay. 6 Double-check your contact information to make sure your shipping and
billing address is correct. 7 Rest your Touch ID-registered finger on the Touch ID button to the far right
of the Touch Bar to confirm that you want to pay with Apple Pay.
New Hardware: Virtual Reality
From the Oxford English Dictionary: virtual reality: The computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.
New Hardware: Virtual Reality
New Hardware: Virtual Reality
If the Mac was not known as not capable of running virtual realty games, this changed with the Mid-2017 iMac, which is not only capable of running virtual reality games, but it is also designed to create virtual reality simulations.
New Hardware: Virtual Reality
Creating hardware to develop virtual reality is only part of the equation. Software must also be available to create the virtual reality simulations. The Mac is able to create these complex simulations through High Sierra’s support of external graphics cards.
New Hardware: External graphics cards
Using an external graphics card is not as simple as just plugging it in. It takes an advanced combination of hardware and software support to be able to utilize an External graphics system. This is now available on Macs with Thunderbolt 3 technology. This includes all late-2016 MacBook Pros, Mid-2017 iMacs and the new iMac Pro. Thunderbolt 3 is also known as USB-C.
New Hardware: External graphics cards
The ability to connect to an external graphics card may only appeal to a small segment of Mac users, but for that group it is an important and significant feature. All applications may not support external graphics right away, but stay tuned for more as this technology develops on the Mac platform.
New Hardware: iMac Pro
The iMac Pro
New Hardware: iMac Pro

High Sierra Safari Update: Safari’s Silent Mode
Safari pauses the videos before they can start to play. Safari also mutes those annoying ads that start to play sound only once you hover over them, even when they would normally get activated. Safari tries to be smart about which sites it
blocks autoplaying video on as well. YouTube, Netflix, Hulu, Twitch, Crackle, Vudu, and DailyMotion are among the sites allowed to autoplay videos with sound turned on by default.

High Sierra Safari Update: intelligent tracking prevention
Disabling Cross-Site Tracking isn't going to cut down on the number of ads that you see, but it will make it harder for advertisers to gather data about what you've been browsing to deliver targeted ads.
Ever browse the web for an item, maybe boots or shoes, and have ads for those boots and shoes show up on Facebook or your news website? Those are cookies that allow this to happen. With High Sierra’s cross-site tracking prevention, you will see fewer targeted ads!
High Sierra Safari Update: intelligent tracking prevention
With Prevent cross-site tracking enabled—and it’s likely it was by default—you should see fewer ads related to something you searched for on another site. It should also stop companies from tracking where you go and what you look at when you go to other websites.
High Sierra FaceTime Update: Live Photos
In iOS 11 and macOS High Sierra, there’s a new camera shutter button on the screen when you’re in a FaceTime call. Tap or click this button (or use the Touch Bar on Macs that have it), and a Live Photo
