How to Boot macOS without USB [Clover/OpenCore]

An EliteMacx86 Exclusive Guide - This guide covers booting of macOS without USB after finishing the installation. By using this method, you’ll be easily able to install the Clover/OpenCore Boot loader on your System Drive which will allow booting.

Booting from the system drive without the use of USB is one of the important parts of the post-installation. To boot macOS without the use of USB, follow the steps below.

QUICK INFO:
  • This guide assumes that a Bootable USB exists and the OS X/macOS has been installed on the target computer.

For Clover Users


If you're using OpenCore as a bootloader and depending on your installation type, either UEFI or Legacy, follow the steps below to boot macOS without USB.

UEFI

The following steps are for the systems running in UEFI Boot Mode.

STEP 1: Mount EFI
The first step is to mount the EFI Partition of your Bootable USB.

STEP 2: Copy EFI
Once the EFI Partition of your macOS Bootable USB has been mounted, the next step is to copy the EFI from it. To copy the EFI, follow the steps below.

1. Open the mounted EFI Partition and copy the EFI folder to your Desktop.
2. Once copied, unmount the EFI Partition of your macOS Bootable USB. You can also eject the partition to unmount it.

STEP 3: Mount ESP
Once you have copied the EFI from your Bootable USB, the next step is to mount the System EFI Partition (ESP).

NOTES:
  • If you see any existing EFI folder in your ESP, delete the folder and empty the trash.
  • The EFI folder in the ESP mainly has the APPLE folder which contains firmware for real Macs. This is specific for real Macs and is irrelevant on non-Apple hardware.

STEP 4: Copy EFI
The next step is to copy the EFI that you obtained in STEP #2 to your ESP. To copy the EFI to your ESP, open your ESP and copy the EFI from the Desktop to the ESP.

Legacy


For OpenCore Users


If you're using OpenCore as a bootloader and depending on your installation type, either UEFI or Legacy, follow the steps below to boot macOS without USB.

UEFI


For OpenCore users running the system in UEFI Boot Mode, the steps are exactly the same as the "Clover" method.

STEP 1: Mount EFI
The first step is to mount the EFI Partition of your Bootable USB.

STEP 2: Copy EFI
Once the EFI Partition of your macOS Bootable USB has been mounted, the next step is to copy the EFI from it. To copy the EFI, follow the steps below.

1. Open the mounted EFI Partition and copy the EFI folder to your Desktop.
2. Once copied, unmount the EFI Partition of your macOS Bootable USB. You can also eject the partition to unmount it.

STEP 3: Mount ESP
Once you have copied the EFI from your Bootable USB, the next step is to mount the System EFI Partition (ESP).

NOTES:
  • If you see any existing EFI folder in your ESP, delete the folder and empty the trash.
  • The EFI folder in the ESP mainly has the APPLE folder which contains firmware for real Macs. This is specific for real Macs and is irrelevant on non-Apple hardware.

STEP 4: Copy EFI
The next step is to copy the EFI that you obtained in STEP #2 to your ESP. To copy the EFI to your ESP, open your ESP and copy the EFI from the Desktop to the ESP.

Legacy

NOTE:
  • Legacy users need to write boot sectors to make the system bootable. Legacy users need to use BootInstallARCH.tool on the target ESP.
