If MultiBeast continues to fail, remember that MultiBeast is essentially a "wrapper" for a collection of kexts and the Clover bootloader. You can do everything MultiBeast does manually: Install Clover:
Sometimes, even the correct version of MultiBeast struggles to auto-mount the EFI partition on APFS drives.
If you downloaded MultiBeast months or years ago, delete it.
If SIP is not fully disabled, macOS will block MultiBeast from moving drivers (kexts) into protected system folders like /Library/Extensions .
Below is a draft blog post designed to help you troubleshoot the issue or pivot to more modern methods.
Reboot your Hackintosh. At the Clover boot screen, press F1 or Spacebar to access the Options menu. Navigate to: Options → System Parameters → CsrUtilConfig Set the value to 0x67 (Disables all SIP flags). Alternative: Boot into Recovery HD, open Terminal, type csrutil disable .
This avoids MultiBeast’s broken installer entirely.
MultiBeast requires deep system access that SIP blocks by default.
Drivers are stored in the EFI partition, not your System folders.
