## Installation

0. **Mandatory** for Tahoe:
   - Remove `USBInjectAll.kext` from `EFI/OC/Kexts`, map your own USB config using USBToolBox's [tool](https://github.com/USBToolBox/tool) and its [kext](https://github.com/USBToolBox/kext) referring to this [usage manual](https://github.com/USBToolBox/tool?tab=readme-ov-file#usage),
   - 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](https://github.com/acidanthera/OcBinaryData/blob/master/Drivers/apfs_aligned.efi).

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](https://github.com/corpnewt/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](https://github.com/corpnewt/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.
