Select your target internal drive and Erase it. | Set Name (any), Format to APFS , and Scheme to GUID Partition Map . | | 6 | Installation | Quit Disk Utility and choose "Install macOS" . Select your newly formatted drive as the destination. | The system will reboot several times. Always boot from the USB and select your installation drive's name , not the installer. | | 7 | Post-Install | Once booted into Catalina, mount your internal drive's EFI partition. Copy the EFI folder from your USB's EFI partition to your internal drive's EFI. | This step makes your Hackintosh bootable without the USB drive. | | 8 | Final Scripts | Run the disablehibernate.command and master.disable.command scripts found in the "Files" folder on the Olarila USB drive. | These scripts are essential for fixing sleep/wake issues and other power management problems. |
