The good news is that macOS High Sierra is a widely compatible system software update for Mac. In fact, if a Mac can run MacOS Sierra, then the same Mac can also run MacOS High Sierra. This includes just about any hardware released from 2010 onward, and a few models from the year prior as well. The next version of Apple’s operating system for the Mac is called macOS High Sierra.While the OS is mostly about software refinements, it also lays the foundation for future innovations in the. Obviously, change “High Sierra.app” to whatever version you’re installing. To provide the application with a path to the volume that will be overwritten. In our case, this is /Volumes/Installer; To provide the application with a path to the installer package. For macOS Sierra, this is /Applications/Install macOS High Sierra.app. The installation of macOS High Sierra will take a while, and when it’s completed the Mac reboots and goes through the setup procedure that is familiar to anyone who has owned a new Mac. You’re asked to enter your Apple ID, create a user account, and setup iCloud.

Apple File System (APFS)

• Metal is Apple’s advanced graphics technology and the fastest, most efficient way to tap into GPU power on the Mac.
• Metal 2 supports next-generation experiences like machine learning used in speech recognition, natural language processing and computer vision.
• Metal 2 features a refined API and improved performance that’s helping developers, including Unity, Epic, Valve, Pixelmator and more, accelerate their future apps.
• With the combination of Thunderbolt 3 and Metal 2, the most demanding Mac users can now access powerful external GPUs.

Core ML

• With Core ML, Apple brings the power of machine learning to all Apple developers, enabling the creation of entirely new kinds of apps.
• Core ML takes full advantage of Metal and Accelerate, delivering incredible power, speed and efficiency to machine learning operations such as computer vision, natural language and support for convolutional and recurrent neural networks.
• All of the computation and processing driven through Core ML is done on-device in a way that respects customers’ data and privacy.
• Developers are already using Core ML to enhance apps like Pixelmator Pro, which uses machine learning to detect and understand various features within images and create intelligent editing solutions.

• macOS High Sierra adds support for VR content creation for the first time, enabling developers to create immersive gaming, 3D and VR content on the Mac.
• Leading VR companies are working with Apple to drive VR innovation on the Mac with features coming later this year.
• Valve is optimizing its SteamVR platform for macOS and enabling connection of the HTC Vive headset, while Unity and Epic are bringing their VR development tools to macOS.
• Later this year, Final Cut Pro X will add support for professional 360-degree VR workflows with the ability to import, edit and export 360-degree video on the Mac.

• An updated, always-on sidebar and new filtering and selection tools make photo organization quick and easy.
• A refreshed editing UI includes powerful new editing tools like Curves, for fine-tuning contrast, and Selective Color, for making adjustments to a specific color range.
• Live Photos can now be edited with fun effects, like Loop, Bounce and Long Exposure, and users can also choose a different key photo.
• Third-party editors like Photoshop, Pixelmator and other apps can be launched from Photos, with edits saved back to the Photos library.
• Support for third-party project extensions provides access to printing and publishing services from Shutterfly, WhiteWall, Wix, ifolor, Mimeo and Mpix from right within the app.

• Safari stops media with audio from automatically playing in the browser, and Reader can automatically open articles in a clean, uncluttered format.
• Intelligent Tracking Prevention in Safari detects and eliminates cookies and other data used by advertisers for cross-site tracking, to help keep a user’s browsing private.
• Siri on the Mac responds with a more natural voice and learns music preferences, creates custom playlists and answers music trivia when using Apple Music.
• Touch Bar on MacBook Pro gets new Control Strip options plus an improved color picker and more video controls.
• Notes adds simple tables, allowing a user to type in cells, make edits and move rows and columns.
• Spotlight provides flight status information, including departure and arrival times, delays, gates, terminals and even a map of the flight path.

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

Mac Os X High Sierra Patcher

• 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.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

* 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:

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:

3. Release the Option key when you see a dark screen showing your bootable volumes.
4. Select the volume containing the bootable installer. Then click the up arrow or press Return.
   If you can't start up from the bootable installer, make sure that the External Boot setting in Startup Security Utility is set to allow booting from external media.
5. Choose your language, if prompted.
6. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
