Understanding Bootable Usb Drives
A bootable USB drive is a portable storage device that allows you to start up your computer from an external source rather than the internal hard drive. This is particularly useful when you need to troubleshoot your system, install a new operating system, or recover data from a non-bootable computer. Creating a bootable macOS Sierra USB involves copying the necessary installation files to the USB drive, enabling you to install or upgrade macOS on multiple devices without having to download the installer separately on each one.
To create a bootable macOS Sierra USB, you will need a USB flash drive with at least 16 GB of storage capacity, the macOS Sierra installer, and a Mac computer. It’s important to note that the USB drive will be completely erased during the process, so make sure to back up any important data before proceeding. Additionally, you can use utilities like Disk Utility or Terminal to format the USB drive and create a bootable installer using the createinstallmedia command, which simplifies the process and ensures a smooth installation of macOS Sierra on your Mac devices.
Preparing Your Usb Drive
To prepare your USB drive for creating a bootable macOS Sierra, ensure that you have a compatible USB drive with a capacity of at least 16GB. Before proceeding, back up any important data stored on the USB drive, as the process will involve formatting the drive, erasing all existing data.
Next, download the macOS Sierra installer from the Mac App Store. Connect your USB drive to your Mac and launch Disk Utility. Select your USB drive from the list of devices on the left side of the Disk Utility window. Click on the “Erase” tab, choose the format as “Mac OS Extended (Journaled),” and give your drive a name. Click “Erase” to format the USB drive.
Once the formatting is complete, open Terminal and run a command to create a bootable installer on the USB drive. Follow the on-screen instructions, and after the process finishes, your USB drive will be ready to use as a bootable macOS Sierra installer.
Downloading Macos Sierra
To begin the process of creating a bootable macOS Sierra USB drive, the first step is to download the macOS Sierra installation file. This can be easily done through the Mac App Store if you already have macOS Sierra installed on your Mac. Simply open the App Store, search for macOS Sierra, and click the download button. The installation file is quite large, so ensure you have a stable internet connection and enough storage space available on your Mac.
If you do not have macOS Sierra already installed on your Mac, you may need to access the download through other means, such as using a friend’s Mac or a public computer. Websites offering the macOS Sierra installer may not always be trustworthy, so it is recommended to download it directly from the Mac App Store for security and reliability. Once the download is complete, the macOS Sierra installation file will be saved in your Applications folder, ready for the next steps in creating your bootable USB drive.
Creating A Bootable Macos Sierra Usb On Mac
To create a bootable macOS Sierra USB on your Mac, you’ll need a USB flash drive with at least 8GB of storage capacity and the macOS Sierra installation file from the Mac App Store. Start by plugging in your USB drive and formatting it to the appropriate file system using Disk Utility. Be sure to rename the USB drive to make it easily recognizable in the process.
Next, use Terminal commands to create the bootable USB installer. Open Terminal and run a simple command to copy the macOS Sierra installation files to the USB drive. This process may take some time, so be patient as the files transfer over. Once the process is complete, you will have a bootable macOS Sierra USB ready for installation on any compatible Mac system.
Having a bootable macOS Sierra USB can be a lifesaver in case of system issues or when you need to install the operating system on multiple devices without re-downloading the installation files. Follow these steps carefully to ensure a smooth creation process and have a reliable backup for your Mac system.
Creating A Bootable Macos Sierra Usb On Windows
To create a bootable macOS Sierra USB on Windows, you will need to use a tool called TransMac. Start by downloading and installing TransMac on your Windows PC. Once installed, insert your USB flash drive into your computer.
Next, run TransMac and right-click on the USB drive you wish to make bootable. Select the ‘Restore with Disk Image’ option and choose the macOS Sierra DMG file you have downloaded. Click on ‘OK’ to begin the process. TransMac will now create a bootable macOS Sierra USB using the disk image file.
After the process is complete, safely eject the USB drive from your Windows PC. You can now use this bootable macOS Sierra USB to install or upgrade macOS Sierra on your Mac device. Remember to adjust your Mac’s boot settings to boot from the USB drive during installation.
Booting Your Mac From The Usb Drive
To boot your Mac from the USB drive, start by shutting down the computer. Insert the bootable macOS Sierra USB drive into any available USB port. Power on your Mac while holding down the Option (⌥) key on your keyboard. This will bring up the Startup Manager, showing you all available boot drives.
Use the arrow keys to navigate to the macOS Sierra USB drive and press Enter to select it. Your Mac will now boot from the USB drive, launching the macOS Sierra installation process. Follow the on-screen instructions to install macOS Sierra on your computer or to perform any troubleshooting tasks you need.
Remember that booting from a USB drive overrides the normal startup process, so once you’re done with the task at hand, you can restart your Mac to boot back into your regular macOS system. It’s a useful tool for recovery, installation, or any other specialized tasks you may need to perform on your Mac.
Troubleshooting Common Issues
When creating a bootable macOS Sierra USB drive, you may encounter some common issues that could hinder the process. One issue that users often face is an incomplete or corrupted download of the macOS Sierra installation file. To troubleshoot this, ensure that you have a stable internet connection and enough storage space on your computer to download the file successfully.

Another common problem is compatibility issues with the USB drive itself. Ensure that the USB drive you are using is properly formatted and meets the necessary requirements for creating a bootable macOS Sierra drive. If the drive is not recognized or is causing errors during the bootable process, try using a different USB drive or formatting the existing one again. Additionally, make sure to follow the step-by-step instructions carefully to avoid any potential errors that could arise during the creation of the bootable drive.
Final Tips And Recommendations
