Hackintosh-OpenCore-EFI-DELL-Optiplex-3050

This repository provides a pre-made EFI setup for the OpenCore bootloader specifically designed for the Dell Optiplex 3050.

[!NOTE] This repository is no longer actively maintained. It is recommended to use it as a reference for creating your own custom EFI configuration rather than relying on it for direct installation. I don’t have access to this hardware anymore.

Current Version - OpenCore 1.0.5 DEBUG

This repository includes a “Plug-and-Play” EFI configuration for the OpenCore bootloader, as well as all the necessary files to install and run macOS on your Dell Optiplex 3050.

Installation

0. Mandatory for Tahoe:

   • Remove USBInjectAll.kext from EFI/OC/Kexts, map your own USB config using USBToolBox’s tool and its kext referring to this usage manual,
   • Disable EnableJumpstart in EFI/OC/Config.plist -> UEFI -> APFS,
   • Disable PollAppleHotKeys in EFI/OC/Config.plist -> Misc -> Boot,
   • Add apfs_aligned.efi to EFI/OC/Drivers from OCBinaryData.

1. First of all, ensure you’re firmware and drivers are generally up to date. Next download the EFI by getting it from assets in Releases page or cloning whole repo.

2. It may still boot with EFI as it is just fine but please ensure to dump your own SSDTs for EFI/OC/ACPI with SSDTTime, remember that every configuration differ even if it’s the same model!

3. The included SMBIOS in this repository is not associated with a purchased Apple device. For your own sake, it’s not recommended to use it. Re-generate iMac20,1 SMBIOS for your EFI using GenSMBIOS. You just need a invalid or unused SMBIOS to copy-paste the required info, especially if you intend to use iServices.

4. The situation may change in the future, depending on Apple’s actions. Thanks to Intel, it appears that spoofing from Kaby Lake to Coffee Lake (KBL -> CFL) is possible so will come in handy if needed.

P.S.: An updated reference image is needed, so if someone achieves success, please consider contributing. This repository started as a result of boredom in class and now that I’ve graduated, it’s become a bit of a guessing game.
