How to Create a Bootable macOS Sierra Installer Easily For the last few years, Apple is pushing its AppStore - both the iOS and macOS - to distribute all applications, including the operating system. In the perfect world, this approach is fine and dandy, but we are not living there. The Mac OS Sierra Download is the most advanced MacOS ever and is packed with several features never seen before. It also improves files storage and security of your mac. Finally, we come to an end to this guide on Download of the Apple MacOS 10.12 Sierra.

  1. TLDR: I had to create a bootable installer from a 2008 macbook I had laying around. This allowed me to use the OLD app store to download the proper installer. My struggle: A prohibitory symbol on my late-2011 Macbook Pro after erasing. I could not re-install the OS using any of the recovery mode options (command, R, option).
  2. A bootable USB installer is a handy tool for fresh installs of macOS High Sierra. Subscribe Read full article http://wp.me/p1xtr9.

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 12GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

  • 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.
Bootable

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.

For the last few years, Apple is pushing its AppStore - both the iOS and macOS - to distribute all applications, including the operating system. In the perfect world, this approach is fine and dandy, but we are not living there.

This “everything on the cloud” method has several disadvantages, especially regarding macOS installer. First, the file size is too big for some to download over the internet. Second, those with more than one Mac has to re-download the installer file several times, once for each machine. It’s a waste of time and internet bandwidth.

Sometimes it’s better to install the macOS using drive installer. But you can’t just copy and paste the downloaded file to a USB drive. You need to create a bootable drive. Here’s the easy way to do it.

Downloading the macOS Sierra Installer

First, find and download macOS Sierra in the App Store. The installer will be saved in the Applications folder and automatically launch after the download, but you need to quit it. Because if you continue with the installation, the installer will be removed from your local hard drive after the process.

You can keep the installer in the Applications folder or make a backup copy in another drive/folder.

Preparing an External Drive

To create the installer, you need a USB flash drive or external hard drive with minimum 8 GB of storage.

During the process, the drive will be reformatted automatically. So if you have valuable data on the drive, it’s wise to back it up somewhere safe.

And don’t forget to change the name of your drive to Untitled because it’s necessary for the next step.

Taking the Quick and Easy Way

You can create the bootable installer drive using the Terminal. But why taking the hard way when there’s the quick and easy way?

You can use one of these two apps to help you with the process:

Bootable

Both apps are fast and straightforward. They also support the older version of OS X.

After downloading one of the two alternatives, all that you need to do is to start the app, choose the installer file, and follow the process. You’ll have the bootable drive in a few minutes.

Booting from the Installer Drive

After creating the bootable installer drive, you need to boot your Mac from it to install Sierra.

  • 1. Plug your external drive into your Mac.
  • 2. Restart your Mac and press down on the Option key while the Mac boots.
  • 3. After a few moments, your Mac should display the Startup Manager, which will show you the available boot drives. Click on the external drive and hit Return.
  • 4. Your Mac will display an OS X Utilities window. If you want to install Sierra and leave the data intact, select Install OS X. If you want to start over and wipe out the data, you need to go into Disk Utility to reformat the internal drive first, and then install macOS Sierra.

Backing up and Recovering Your Data

Whether you choose the clean install or upgrade your previous version of macOS, the process bears the risk of losing your data. To keep your data safe, there’s no other option than to back it up so that you can recover it later.

You can use the help from Tenorshare Data Recovery for Mac. This app is a complete Mac data recovery solution to recover all types of files from Mac's hard drive and also from other portable devices like USB flash drive, external hard drive, SD card, iPhone. The app supports all macOS versions including macOS High Sierra, EI Captain, Yosemite, or below.
