Mac Os X Sierra Bootable Usb

Sep 27, 2017 The simplest way to create a boot USB drive is to download DiskMaker X and use it to create your drive. Generally, the latest version supports only the latest version of macOS; if you want to install something older than macOS High Sierra, check the list of older versions and download one that’s compatible with your chosen operating system.

  • Step 1: To begin, download macOS High Sierra 10.13 installer app from the Mac App Store. The app will be titled, “Install macOS High Sierra”. Step 2: Connect the aforementioned USB flash drive to your Mac, and then launch the Disk Utility app to format the connected flash drive. Once the app opens, make sure that it is selected in the left.
  • Here are the steps I took to create the bootable USB drive (I have a Mid-2014 MacBook Pro with Retina Display): Downloaded the latest OS X El Capitan (10.11.3) from the Mac App Store. Created a bootable USB drive using createinstallmedia (as explained in Apple’s documentation) and it went well. Erased Macintosh HD. Tried booting from USB drive.

DiskMaker X is an application built with AppleScript that you can use with many versions of OS X to build a bootable drive from macOS installer program (the one you download from the Mac App Store). As soon as you launch the application, it tries to find the macOS Install program with Spotlight.

Then, it proposes to build a bootable install disk and make it look as nice as possible. It’s the easiest way to build an macOS Installer in a few clicks !

You can use the Install drive to fully re-install the OS on a freshly formated drive, or install it on your many Macs without re-downloading the full installer.

Jump over the break to learn how to use DiskMaker X…

1. Get an an empty flash drive with at least 8GB of storage

4. Double-click on the .dmg file to open it and drag-and-drop the DiskMaker X app into the Applications folder

5. Now load DIskMaker X. When you load the app, it will ask you which version of macOS do you want to make a boot disk of. You can choose Yosemite, El Capitan and of course, Sierra. We’ll choose macOS Sierra

6. Now, the app will search for a copy of macOS Sierra. Once it found your Sierra copy, it will ask you if you want to use the copy that it found or you want to use another copy. If you downloaded it from the app store ( step 2 ), choose ‘Use this copy’

7. The app will ask you about your thumb drive, and it will tell you that will be completely erased before copying macOS Sierra onto it…

8. Now the app will format your flash drive and ask you for your admin password. Once you enter your admin password, DiskMaker X will start copying the necessary Sierra files onto your flash drive.

NOTE: this process will take a while. Be patient….

9. When you’re done, the app will tell you that the boot disk is ready, you’ll see that your flash drive has been renamed as macOS 10.12 Install Disk and it will be opened. Now all you have to do is restart your Mac and and after you here the chime sound, press the Option ( Alt ) key until you see the option to choose the flash drive to boot from.
