Disclaimer: This repository is for educational purposes only. I am not responsible for any damage caused to your device. Please proceed with caution. I don't provide any help unless you're meeting following requirements:
This EFI supports only Dell Optiplex 3050 CPU i3-7100 (Any Kaby Lake CPUs apply) iGPU HD 630 dGPU For dGPUs to work, remove iGPU args from DeviceProperties Motherboard DELL's OEM board Supported macOS version 15.0 (24A335) -
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! -
(Optional) Remove
USBInjectAll.kextfromEFI/OC/Kexts, map your own USB config using USBToolBox's tool and its kext referring to this usage manual -
Please be aware that Apple has not removed any of the kexts for Kaby Lake's iGPUs yet. To run macOS 14+, you should change your SMBIOS to
iMac19,1, which is now set by default. -
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
iMac19,1SMBIOS 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.
