  2. Launch OpenCore Legacy Patcher. You can usually find it in your Applications folder.

  4. Choose the download method:
    • Download macOS Installer: If you haven’t downloaded the macOS Sonoma installer yet, select this option. OpenCore will guide you through the download process.
    • Use existing macOS Installer: If you already have the downloaded macOS Sonoma installer file on your computer, select this option and locate the file using the file selection dialog.
  5. Follow the on-screen prompts: Once you’ve chosen the download method, OpenCore will either download the installer or prompt you to select the existing installer file. Wait patiently for the download or validation process to complete.
  6. Confirm the creation of the bootable installer: When prompted, click “Yes” to allow OpenCore to create a bootable macOS Sonoma installer on your chosen USB disk.
  7. Select the installation source: Choose the downloaded macOS Sonoma installer file.
  8. Choose your USB disk: A list of available disks will be displayed. Carefully select the USB drive you want to use. Make sure to choose the correct drive to avoid accidentally erasing data on other drives.
  9. Click “Confirm” to start the creation process. OpenCore will format the USB drive and copy the necessary files to create a bootable installer. This process may take some time, so be patient.
  10. Congratulations! Once the process is complete, you will have a bootable USB drive containing the macOS Sonoma installer.

Before getting away!!! Don’t close the OpenCore window as we are following in the Step 3.

Step 3. Installing OpenCore

The final step involves installing OpenCore onto the newly created bootable USB drive. This enables OpenCore’s functionalities to facilitate the macOS Sonoma installation process.

  1. On the final screen of “Creating a Bootable USB for macOS Sonoma,” you’ll be prompted with the question: “Would you like to continue and Install OpenCore to this Disk?” Select “Yes” to proceed.
  2. A new window will appear asking you to “Install to Disk” again. This step confirms your intent to install OpenCore onto the bootable USB drive you just created.
  3. Select the USB drive you used in the previous step to create the bootable installer. Ensure you choose the correct drive to avoid unintended consequences.
  4. Next, select the “Disk with EFI” partition. This is typically a small partition on the USB drive used for storing configuration files.
  5. Enter your administrator password when prompted. This is necessary to grant OpenCore the necessary permissions to modify the USB drive’s EFI partition.
  6. Congratulations! You’ve successfully installed OpenCore onto your bootable USB drive.

Step 4. Restarting Mac to Startup Manager

Once you’ve completed the previous steps and have a bootable USB drive with OpenCore installed, it’s time to begin the actual macOS Sonoma installation process.

  1. Perform a system restart: Power down your Mac and then turn it back on.
  2. Hold down the Option key immediately after hearing the startup chime. This key combination triggers the boot selection menu.
  3. In the boot menu, select the “EFI Boot” option. It might appear with an OpenCore logo or the name of your USB drive.
  4. Once the boot selection is confirmed, the macOS Sonoma installer will launch or you can go to the Disk Utility and perform a clean Installation. It is rather up to you to decide.

  5. The installation process will now begin. The estimated time may vary depending on your hardware configuration and chosen installation option. Be patient and avoid interrupting the process once it starts.

Important Note:

  • During the installation, your Mac might restart several times. This is normal behavior and does not indicate any issues.
  • Do not power off or disturb your Mac while the installation is in progress. This could lead to unexpected errors or incomplete installations.

Step 7. Post Installation configuration
