Making a bootable MacOS USB drive in Windows.

1. Run gibMacOS.bat as administrator
2. Press “r” to toggle recovery only
3. Download the most recent full install version
4. Open MakeInstall.bat as Admin and select your drive with option O for OpenCore( ex: 1O).
5. After formatting the disk, copy and paste the path of RecoveryHDMetaDMG.pkg inside the folder of “macOS Downloads” in the “gibMacOS” directory.

Cleanup Drivers and Tools

1. Remove from EFI/OC/Drivers:

• OpenUsbKbDxe.efi: Used for OpenCore picker on legacy systems running DuetPkg, not recommended and even harmful on Ivy Bridge and newer
• UsbMouseDxe.efi: similar idea to OpenUsbKbDxe, should only be needed on legacy systems using DuetPkg
• NvmExpressDxe.efi: Used for Haswell and older when no NVMe driver is built into the firmware
• XhciDxe.efi: Used for Sandy Bridge and older when no XHCI driver is built into the firmware
• HiiDatabase.efi: Used for fixing GUI support like OpenShell.efi on Sandy Bridge and older
• OpenCanopy.efi: This is OpenCore’s optional GUI, we’ll be going over how to set this up in Post Install so remove this for now
• Ps2KeyboardDxe.efi + Ps2MouseDxe.efi: Pretty obvious when you need this, USB keyboard and mouse users don’t need it
• crscreenshot.efi

Get Firmware Drivers

Gathering files

• Add HfsPlus.efi for reading Hfs filesystems.

In total there are three drivers, AudioDXE.efi, OpenRuntime.efi and HfsPlus.efi.

Get Kexts

Get Kexts from this Kexts Repo.

These are all the kexts you will need.

ACPI SSDT

Get SSDTTime from this link.

1. Run SSDTTime
2. Press 4 for DumpDSDT
3. Press 2 for Fake EC
4. Copy results in the same folder (except DSDT.ami) to ACPI folder under EFI/OC

Edit your own config.plist

• Download OpenCorePkg’s releases.
• Rename the sample.plist file in OpenCorePkg/Docs to config.plist.
• Copy the file to “EFI/OC” on the USB.
• Download ProperTree to edit the plist file.
• Open your config.plist in the app.
• And change all configurations mentioned in link.
• Use CorpNewt’s GenSMBIOS application to generate SMBIOS info, and add it to config.plist.

Disabled: SetupVirtualMap may be needed depending on the firmware, generally this quirk should be avoided but most Gigabyte users and older hardware(Broadwell and older) will need this quirk to boot.

Added SSDT-AWAC.aml to config.plist

Now we’ve made a bootable macOS USB

Bios Settings

Boot from USB Drive

You should probably install macOS successfully. If there are any error occurs, find the output error in this guide.

Post Installation

Boot without USB:

• Mount your EFI partition with this tool.
• Copy the EFI folder on the USB to the mounted EFI on the main computer.

Fixing Audio:

Check if all your audio jacks work, if not, you may want to try the fix mentioned down below.

Thanks for rcozinheiro for the solution.

1. Add these three kexts to the EFI/OC/kexts folder:

• AppleALC.kext
• FakePCIID.kext
• FakePCIID_Intel_HDMI_Audio.kext

2. And edit the config.plist by adding under DeviceProperties -> Add:

• PciRoot(0x0)/Pci(0x1F,0x3)
• device-id data 70A10000
• layout-id data 01000000

3. Remove the alcid argv at NVRAM->Add->7C436110-AB2A-4BBB-A880-FE41995C9F82->boot-args in config.plist.
