Download macOS

Find the appropriate download link in the upgrade instructions for each macOS version:

macOS Catalina, macOS Mojave, ormacOS High Sierra
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. Library location in mac. 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.

OS X El Capitan
El Capitan downloads as a disk image. 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. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
  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 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.
    Catalina:*
    Mojave:*

    High Sierra:*
    El Capitan:
  4. Press Return after typing the command.
  5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
  7. 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:

  1. Plug the bootable installer into a compatible Mac.
  2. 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.
  3. Choose your language, if prompted.
  4. 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.
  5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Of the many files and folders that make up macOS Sierra, there’s probably none so important to maintaining the “personality” of your Mac than the ~/Library folder. Inside this folder are many subfolders that contain preference lists (“plists”), database files storing a variety of important information, and many other files that maintain the state of macOS and of the individual apps that run on a Mac. Thanks to the importance of this folder, it’s normally hidden from view. Today we’ll show you a few ways to view the ~/Library folder.

Warning: Don’t play with the ~/Library folder if you don’t need to!
Before we go any further, it’s time for a warning. Don’t throw away or change anything in the ~/Library folder unless you know what you’re doing. Deleting individual files or folders found within ~/Library can cause individual applications or the operating system to malfunction.

When would you want to poke around in ~/Library? Perhaps you’re gaining knowledge about macOS as a developer and want to know how the operating system stores information. Maybe you want to clean out the remnants of an app that you haven’t had on your Mac for several years. In any case, it’s best to remember what your parents told you when you were a kid and were in a place filled with expensive and breakable things — “Look, but don’t touch!”

Method One: Our Friend, the Option Key
The first and easiest way is to use a trick that gives many of the items in the macOS menu bar “super powers” — hold down the Option key while clicking on a menu. In this case, Option-clicking the Go menu in the Finder adds a new menu item — Library — that opens the ~/Library folder (see image below):

As you can see from the image above, holding down the Option key while clicking on the Go menu in the Finder adds one item as seen on the right — the Library folder. Select that menu item and a window similar to the one seen below opens on the Mac screen:

Of these folders, Application Support is quite critical as it holds information for the current user’s apps. You’ll see many “.plist” files; these are XML (Extensible Markup Language) files that can be viewed on the Mac by simply highlighting the file and pressing the space bar to bring up a Quick Look. There are also a number of log files (text-based), temporary files, app plugins, and database files (.db or .sqlite) that are critical to storing settings and data in your favorite apps.

Method Two: Command-Shift-Period
The second method works from any open Finder window, and it uses the keyboard shortcut Command-Shift-. (that dot indicates the period key). This is a fun command, as it makes any hidden files or folders visible in the Finder. On the left in the image below you see my Home folder. Pressing Command-Shift-. makes hidden folders and files appear as shaded icons, shown on the right:

Pressing Command-Shift-Period makes hidden files and folders visible (right image)

See that Library folder in the center of the list on the right? Even though it is shaded, it can be double-clicked to open and view everything that’s in the folder. What’s more, some of the files that are not visible in the ~/Library folder when using Method One appear when using Method 2.

One other thing to note: Command-Shift-. makes these files and folders visible until the next time you use the command or reboot the Mac. If you’re poking around in the ~/Library folder on a Mac that other people may use without having their own logins, be sure to press Command-Shift-. one more time to set things back to hidden once you’re done. Note that Command-Shift-. also makes Library visible in the Finder Go menu without having to press the Option key…

Just remember, anything you change or delete in the ~/Library folder can affect how your Mac or individual applications work, so use these methods to just view hidden files or folders. Don’t delete the files or folders in ~/Library unless you know what you’re doing.
