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.

Supports the latest Macs with Fusion drives while still supporting many PowerPC models. We put in extra effort to continue support all the way back to Mac OS X Leopard (10.5.8). Supports MacBook, MacBook Air, MacBook Pro, iMac, iMac Pro, Mac mini and Mac Pro.

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. 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:

Disk
  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.

An important application in your maintenance toolbox is the Disk Utility, which is located in the Utilities folder within your Applications folder. When you first run this program, it looks something like Figure 1, displaying all the physical disks and volumes on your system.

Figure 1: The familiar face of Tiger’s Disk Utility.

The Disk Utility application has its own toolbar that you can toggle on and off. Click the lozenge-shaped button at the upper-right corner of the window to display or hide the toolbar.

Displaying the goods on your disks

The volume tree structure on the left of the Disk Utility window lists both the physical disks and the partitions that you’ve set up. A partition is nothing more than another word for volume, which is the formatted section of a disk that contains data. A single physical hard drive can contain several partitions. The information display at the bottom of the Disk Utility window contains data about both the volumes and the partitions on your hard drive.

To illustrate: Clicking a drive labeled at the top of the tree displays a description of the drive itself, including its total capacity, interface (connection type), and whether the drive is internal or external, as shown in Figure 2.

Clicking the tree entry for a partition, however, displays information about the type of formatting, the total capacity of the partition and how much of that is used, and the number of files and folders stored on the partition (see Figure 3).

Playing doctor with First Aid

From the First Aid pane, Disk Utility can be used to verify (or check) any disk (well, almost any disk) for errors, as well as repair any errors that it finds. Here are the two exceptions when the buttons are disabled:

  • The start-up disk: Disk Utility can’t verify or repair the start-up disk — that’s Mac talk for the boot drive that contains the Mac OS X system that you’re using at the moment — which makes sense if you think about it because that drive is currently being used!
    If you have multiple operating systems on multiple disks, you can boot from another Mac OS X installation on another drive to check your current start-up disk. Or, you can boot your system from the original Mac OS X installation CD and run Disk Utility from the Installation menu.
    Your start-up disk is automatically verified and repaired (if necessary) during the boot procedure, so you really don’t need to worry about checking the start-up disk.
Mac
  • Write-protected disks: Although you can use the Disk Utility to verify CDs, DVDs, and write-protected removable disk drives (like a write-protected Zip disk), it can’t repair them.
    You also can’t repair a disk that has open files that are currently being used. If you’re running an application from a drive or you’ve opened a document that’s stored on that drive, you won’t be able to repair that drive.

You can also elect to verify and repair permissions (also called privileges) on a disk; these are the read/write. If you can’t save or move a file that you should be able to access, check that drive for permissions problems. Unlike fixing disk errors, you can verify and repair permissions on any volume that contains a Mac OS X installation (whether it was used to boot your Mac or not).

In order to verify or repair, you must be logged in as an admin-level user.

To verify or repair a drive, first select the target volume/partition in the list at the left. To check the contents of the drive and display any errors, click the Verify Disk button. Or, to verify the contents of the drive and fix any problems, click the Repair Disk button. Disk Utility displays any status or error messages in the scrolling list; if you’ve got eagle eyes, you’ll note that the window can be resized so that you can expand it to display more messages. (You can also drag the dot between the left and right panes to expand the list.)

Check your disks once every two or three days. If your Mac is caught by a power failure or Mac OS X locks up, however, it’s a good idea to immediately check disks after you restart your Mac. (Don’t forget that the start-up volume is automatically checked and repaired, if necessary.)
