Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: 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.

Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still 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.

Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the --applicationpath
argument, similar to the way this argument is used in the command for El Capitan.
Use the bootable installer
After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

In the Apple macOS operating system, a package is a file system directory that is normally displayed to the user by the Finder as if it were a single file. [1] Such a directory may be the top-level of a directory tree of objects stored as files, or it may be other archives of files or objects for various purposes, such as installer packages, or backup archives.
Definition[edit]
The package is a common file system abstraction used by Apple operating systems, such as macOS and iOS. It is a directory that may contain a hierarchy of files or objects that represent a preserved, organized state. A package is displayed to users like a single file in the Finder application to avoid being changed by the user. However, the content of packages may be accessed through special keyboard and mouse combination events. For this purpose, the control-click, or right-click, menu displays a directive Show Package Contents.[1]
Some documents may be represented as packages:[2]
- Rich Text Format documents with images, which carry the .rtfd extension;
- Dashboard widgets;
- Partially downloaded files in Safari, which carry the .download extension;
- Final Cut Pro X Camera Archives, which contain multiple QuickTime videos and carry the .fcarch extension;
- project files in GarageBand, Keynote, Pages, Numbers, iMovie and Xcode;
- Installer packages.
The Uniform Type Identifier (UTI) for a package is com.apple.package.[3]
