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This repository is no longer actively maintained.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

Mandatory for Tahoe:
- Remove 
USBInjectAll.kextfromEFI/OC/Kexts, map your own USB config using USBToolBox's tool and its kext referring to this usage manual, - Disable 
EnableJumpstartinEFI/OC/Config.plist->UEFI->APFS, - Disable 
PollAppleHotKeysinEFI/OC/Config.plist->Misc->Boot, - Add 
apfs_aligned.efitoEFI/OC/Driversfrom OCBinaryData. 
 - Remove 
 - 
First of all, ensure you're firmware and drivers are generally up to date. Next download the EFI by getting it from assets in
Releasespage or cloning whole repo. - 
It may still boot with EFI as it is just fine but please ensure to dump your own SSDTs for
EFI/OC/ACPIwith SSDTTime, remember that every configuration differ even if it's the same model! - 
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
iMac20,1SMBIOS 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. - 
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.
