How to Create Recovery Media for Mac OS High Sierra
Welcome to our comprehensive guide on creating recovery media for macOS High Sierra. In this article, we will walk you through the step-by-step process of creating a bootable USB or external drive that can be used to recover your Mac in case of a system failure or other emergencies.
Having a recovery media is essential for every Mac user, as it provides a secure and reliable way to restore your system to a previous state. Whether you want to downgrade to an earlier version, reinstall the operating system, or troubleshoot issues, having a bootable recovery drive can save you time and frustration.
Creating recovery media for macOS High Sierra is a straightforward process that can be done using either the built-in Disk Utility or a third-party application. In this guide, we will cover both methods, so you can choose the one that best suits your needs and preferences.
Before we begin, please note that creating a bootable recovery drive will erase all data on the destination device. Therefore, it is crucial to back up any important files or documents before proceeding. Additionally, make sure you have a USB or external drive with sufficient storage capacity, preferably at least 8GB or higher, to accommodate the recovery media.
Step 1: Prepare a USB Drive
Before you can create a recovery media for macOS High Sierra, you will need to prepare a USB drive. Follow these steps to ensure your USB drive is ready:
1. Choose a compatible USB drive that has a sufficient storage capacity. A minimum of 12 GB is recommended, but a larger capacity is better to accommodate future updates.
2. Connect the USB drive to your Mac using a USB cable or adapter, if necessary.
3. Open “Disk Utility” on your Mac. You can find it in the “Utilities” folder within the “Applications” folder.
4. Select the USB drive from the list of devices on the left side of the “Disk Utility” window.
5. Click on the “Erase” button at the top of the window.
6. In the “Format” drop-down menu, choose “Mac OS Extended (Journaled)” as the file system format.
7. Enter a name for your USB drive in the “Name” field.
8. Click on the “Erase” button to format the USB drive. This will erase all existing data on the drive, so make sure you’ve backed up any important files.
9. Once the formatting process is complete, close “Disk Utility.”
Your USB drive is now ready to be used as a recovery media for macOS High Sierra. Proceed to the next step to create the recovery media.
