1. Boot into the macOS installer

• Plug in your Hackintosh USB installer.
• At the OpenCore/Clover boot picker, choose “Install macOS …” (the installer).
• Wait until you reach the macOS Utilities screen.

2. Open Terminal

• In the top menu bar, click Utilities → Terminal.
  (This gives you a terminal even if your system disk can’t boot.)

3. Find your EFI partition

In Terminal, type:

diskutil list

• This shows all disks and partitions.
• Look for your macOS drive (usually disk0).
• The EFI partition is typically disk0s1, 200 MB, formatted as EFI.

4. Mount the EFI partition

Example:

diskutil mount disk0s1

After this, the EFI partition will appear in Finder as EFI.

5. Access your backup EFI

• Also mount your macOS main partition (APFS or HFS+). Example:

diskutil mount disk0s2

• Now you can browse to your Desktop/Documents folder where your backup EFI is stored:
  Path will be something like /Volumes/Macintosh HD/Users/YourName/Desktop/EFI.

6. Copy backup EFI to EFI partition

Use Terminal cp -R to copy:

cp -R "/Volumes/Macintosh HD/Users/YourName/Desktop/EFI" /Volumes/EFI/

⚠️ Make sure to delete the broken EFI first if it exists:

rm -rf /Volumes/EFI/EFI

Then copy:

cp -R "/Volumes/Macintosh HD/Users/YourName/Desktop/EFI" /Volumes/EFI/

7. Reboot

reboot

Remove the USB → system should boot from your restored EFI.

📌 Note

If you renamed your macOS volume to masOS, replace Macintosh HD with masOS in all commands.

For example, to copy your EFI backup:

cp -R "/Volumes/masOS/Users/YourName/Desktop/EFI" /Volumes/EFI/

Additional commands

1. Mount the macOS partition:

diskutil mount disk0s2

2. Go to your Desktop folder:

cd "/Volumes/masOS/Users/YourUserName/Desktop"

• Replace YourUserName with your macOS account name.

• To check usernames:

ls "/Volumes/masOS/Users"

3. List files/folders on Desktop:

ls
