Main innovations:
• Move mountains with new technologies. New base technologies in macOS High Sierra have allowed to improve the basic functions of Mac. Today, Mac is a new storage architecture, improved video viewing capabilities, full access to the resources of powerful graphics processors. And not only.
• Apple file system. New top management data. Documentation. Photo. Mail. Applications. Everything that's so important to you is perceived by the Mac as data. And the file system is responsible for organizing this data in the form of files and folders and gives you access to them. Our previous file system was developed for the early Mac models and perfectly coped with their tasks. But the modern Mac is based on flash drives, and this opens up great opportunities for innovation. Therefore, it's time to lay the foundation for the future. In macOS High Sierra, we are introducing for the first time on Mac the Apple file system with an improved architecture that provides a new level of security and speed.
• HEVC. The new video standard. On the growing popularity of video 4K Mac meets the new standard HEVC (High Efficiency Video Coding), also known as H.265.1 It is able to compress video up to 40% stronger than the current H.264 standard. Therefore, video files in HEVC format are transmitted faster and take up less space without sacrificing quality.
• Metal 2. New graphics rules. Today, for effective work on the Mac, the graphics processor is more important than ever. And graphics processors are becoming more and more powerful. Metal technology, built into macOS, allows applications to use the graphic potential of the computer to the maximum. Its new version of Metal 2 is not only a new level of image quality, but also the possibility of machine learning, support for virtual reality and external graphics processors in entertainment and professional applications. With Metal 2, you can incorporate the imagination into full power - and playing games, and creating content, and developing software.
• Virtual Reality for Mac. Brave new world. Thanks to macOS High Sierra, developers can create for the first time on Mac interactive virtual reality applications. This is possible on a new iMac with a Retina 5K display, a new iMac Pro, and on other supported Mac models when an external video card is connected. The system has improved support for VV VaV points from Valve and VR helmet HTC Vive. Particular attention is paid to the work of applications to create visual content - such as Final Cut Pro X, Epic Unreal 4 Editor and Unity Editor. Now the developers have everything to immerse you in new exciting worlds.

How to install:
Update
1. Mount the disk image
2. Copy "Install macOS High Sierra" in the "Programs" folder
3. Run the copied application
Clean installation from a flash drive
Step one
1. Mount the downloaded image of macOS 10.13 [MAS] .dmg
2. A window appears with the file "Installing macOS High Sierra.app"
3. This file must be transferred to the Programs folder
Either use DiskMaker X, skip all the below and immediately proceed to the fourth step.
Step Two
We format the drive in the Mac OS Extended (journaled) format with the GUID partition scheme:
1. Open the Disk utility, select the drive (flash drive).
2. Select the "Disk partition" tab, in the list of sections, select "Section 1".
3. Open the "Options", select the GUID partition scheme.
4. In the column "Format" choose Mac OS Extended (journal).
5. "Name" is USB. Click "Apply".
Note: OS X El Capitan and newer format is called OS X Extended (journaled).
Step Three
1. Start the program Terminal (Programs / Utilities / Terminal), insert the following command (the command is entered without moving the lines - just copy and paste it whole) and press Enter, confirm the action by entering the administrator password:
(despite the fact that when you type the password will not be displayed, it is still entered).
Code:
sudo / Applications / Install \ macOS \ High \ Sierra.app/Contents/Resources/createinstallmedia --volume / Volumes / USB --applicationpath / Applications / Install \ macOS \ High \ Sierra.app
After 10-15 minutes, the terminal will complete the creation of the boot flash drive. In the process, you will see the following:
Code:
Erasing Disk: 0% ... 10% ... 20% ... 30 ...
Copying installer files to disk ...
Copy complete.
Making disk bootable ...
Copying boot files ...
Copy complete.
Done.
When Done appears, your bootable flash drive will be ready.
Step Four
If you make all the necessary backups, you can start a clean installation. Reboot the computer with the USB drive connected, holding alt (Option) at startup. Choose our flash drive, in the window that appears, go to Disk Utility, erase the drive of our Mac (in no case to confuse it with a USB flash drive) and proceed to install the High Sierra.
