Master the Art of Erasing High Sierra from your iMac!
Erasing an iMac running High Sierra involves wiping the data from the computer’s hard drive and reinstalling the operating system. Here’s a detailed step-by-step guide on how to erase your iMac:
Before you begin, back up your data: Ensure you have a complete backup of your important files, applications, and settings. You can use Time Machine to perform a full backup or manually copy your data to an external drive. Once your data is backed up, follow these steps:
- Create a macOS High Sierra Bootable USB Drive:
- If you don’t have a macOS High Sierra bootable USB drive, you’ll need to create one. You can do this on another Mac by downloading the High Sierra installer from the App Store and using a tool like DiskMaker X to create the bootable drive.
- Restart Your iMac:
- Insert the bootable USB drive into a USB port on your iMac.
- Access Startup Options:
- Restart your iMac, and as it reboots, hold down the ‘Option’ key on your keyboard until you see the Startup Manager.
- Select the Bootable USB Drive:
- Use your arrow keys to select the bootable USB drive from the Startup Manager and press ‘Enter’ to boot from it.
- Erase the Hard Drive:
- Once the macOS Utilities screen appears, select ‘Disk Utility’ from the options.
- In Disk Utility, locate your iMac’s internal hard drive (usually named “Macintosh HD” or something similar) in the left sidebar.
- Select the hard drive and click on the ‘Erase’ button.
- Choose ‘Mac OS Extended (Journaled)’ as the format, and give your drive a name.
- Click ‘Erase’ to begin the process.
- Reinstall macOS High Sierra:
- Exit Disk Utility once the erasing process is complete.
- In the macOS Utilities window, select ‘Reinstall macOS.’
- Follow the on-screen instructions to reinstall macOS High Sierra on your iMac.
- Restore Data:
- After the installation is complete, you’ll have a fresh, clean High Sierra installation.
- You can choose to restore your data from your backup using the Migration Assistant during the setup process.
- Reinstall Apps:
- Reinstall your applications from the App Store or original installation media.
By following these steps, you’ll effectively erase your iMac running High Sierra and start with a clean installation of the operating system, ensuring your iMac is ready for a fresh start.
