Createinstallmedia Commands For Other Versions Of Macos

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.

Download macOS High Sierra, Mojave or Catalina from Appstore. Plug in an empty USB drive. Run one of the below commands in your Terminal to prepare the bootable macOS USB. Use the ‘createinstallmedia’ command in Terminal. After downloading the installer, connect your Mac to the USB flash drive or other volume that will be used as the bootable installer. Make sure that it has at least 12GB of available storage.

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

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.
Catalina:*
Mojave:*

High Sierra:*
El Capitan:
Press Return after typing the command.
When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
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.
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.

Normally, most macOS updates do not cause any issues on your Mac. However, there are times when certain updates break features and make your system buggy. If you’ve been a victim of such an issue, you might want to roll back the update on your Mac.

Getting back to your favorite-old macOS version isn’t straightforward, though. There’s simply no option anywhere on your Mac that lets you downgrade macOS to an older version of the operating system.

That’s not to say that there’s no method at all to downgrade macOS on your Mac. There are actually a couple of ways to help you roll back the update and get back to the version of macOS you were running prior to updating the machine.

Downgrade macOS By Restoring a Time Machine Backup

If you’ve been a Mac user for quite some time, you probably already know what a Time Machine backup is. It’s a full backup of your Mac containing all of your files, apps, and even the system files.

The great thing about a Time Machine backup is that it backs up your operating system as well. What that means is if you had created a Time Machine backup prior to updating to the latest macOS version, you can restore the backup and get your Mac downgraded.

Caffeine alternative for macos mojave. Restoring the backup restores all of your files, apps, and the older version of macOS you had when you made the backup.

Turn off your Mac by clicking on the Apple logo at the top and selecting Shut Down.

Connect your Time Machine backup disk to your Mac and make sure it’s turned on.
Press the Power button on your Mac to turn it on. Then immediately press and hold down both Command and R buttons at the same time. This’ll reboot you into the Mac recovery mode.

The macOS Utilities list will appear on your screen. Click on the first one in the list that says Restore From Time Machine Backup to restore your backup.

You’ll be asked to choose the disk where your backup is saved. Select your disk from the list on your screen and click on Continue to proceed with restoring the backup.

On the following screen, you’ll see the backups available on your chosen disk. You’ll also see the macOS version of each of your backups so you know exactly what version of macOS you’re downgrading your Mac to.
Select the backup and click on Continue.

Select your main Mac drive on the following screen and hit Restore. It’ll replace all the contents on your drive with the ones from your backup.

Restart your Mac when the backup is restored and you’ll be back to an older version of macOS.

Downgrade macOS By Installing An Older Version Of macOS

If you didn’t create a Time Machine backup before updating to the latest macOS, you can’t use the above method. However, Time Machine isn’t the only way to downgrade the macOS version on your Mac.

You can actually download and install a fresh version of an old macOS on your Mac. This’ll bring your machine to your chosen version of the operating system. Keep in mind though this will erase all the data on your Mac.

There are three stages to use this method.

Download An Old Version of macOS

Since you’ll be installing a fresh copy of macOS, you’re going to need to first download the entire operating system to your Mac.

If you search the official Mac App Store like you normally do to find new macOS versions, you’re only going to be disappointed. It’s because, although the App Store has older versions of the operating system available for download, those aren’t always displayed in the search results.

Your best option is to use the direct download links given below to get your preferred version of macOS for your Mac.

When the file is downloaded, don’t open it just yet. Move it to the Applications folder using the Finder.

Create a Bootable macOS USB Installer
