Downloading and Installing OpenCore Legacy Patcher on macOS USB Installer

  • Enable Verbose (-v) mode.
  • In the SMBIOS section, select a suitable Model for your macOS.

Tip: Verbose mode is a feature that provides detailed information about the boot process of your Hackintosh or macOS system. It’s similar to the verbose mode in macOS, but in the context of OpenCore, it’s specifically related to the bootloader’s activity. Enabling verbose mode in OpenCore can be useful for troubleshooting boot issues, identifying potential errors, and understanding how the boot loader loads various components during startup.

Tip: It’s important to note that macOS Sonoma only supports certain Mac models, so make sure to select the model that aligns with your Mac. You will select a Mac version that is supported by macOS Sonoma and also aligns with your current Mac.

To begin the installation of macOS Sonoma on unsupported Mac; these two options are enough. However; if you got any issues during the installation then you can change the settings here. Now exit the settings.
