Overview

What this repository is for.

The repository contains the EFI boot environment used by OpenCore. It does not contain macOS and it is not a macOS installer.

OpenCore starts before macOS. It provides the ACPI patches, UEFI drivers, kernel extensions and device properties needed for macOS to recognize the OptiPlex hardware correctly.

The current configuration uses an iMac19,1 SMBIOS and is set up around Intel HD Graphics 630, onboard audio, Realtek Ethernet, USB and Dell hardware sensors.

Installation

How to use the EFI.

The EFI is intended as a starting point for a compatible OptiPlex 3050. Keep a backup of a known-working EFI before changing your installation.

  1. 1

    Create the macOS installer

    Obtain macOS from Apple and create your installer or recovery media separately.

  2. 2

    Prepare and mount the EFI partition

    Mount the EFI partition of the installer USB or the target disk before copying the OpenCore files.

    Copy this repository's EFI

    Place the EFI folder from this repository at the root of the EFI partition. The final path must contain EFI/BOOT and EFI/OC.

  4. 4

    Generate your own SMBIOS identifiers

    Keep the iMac19,1 model, but generate unique SystemSerialNumber, MLB, SystemUUID and ROM values before using Apple services.

  5. 5

    Check the BIOS configuration

    Use settings appropriate for OpenCore/macOS, including UEFI boot and AHCI for SATA. Some options may not exist in the Dell BIOS.

  6. 6

    Boot OpenCore and install macOS

    Select the OpenCore UEFI entry from the Dell boot menu, then choose the macOS installer and follow the installation process.

  7. 7

    Move OpenCore to the internal drive

    Once macOS boots correctly from USB, copy the working EFI to the EFI partition of the internal macOS drive so the machine can boot without the installer USB.
