OK, Let’s start. How to use it?
- Download latest EFI files (EFI_ms7c75_xxx.zip) from Releases and unzip it. Please note that there may be Pre-release versions which can be unstable but includes new features.
- Customize your USBPorts.kext. You can get the template from USB.zip.
Just delete the unneeded ports according to the callout (JUSBx) next to the USB ports in use on the motherboard.
Customization is finished when 15 ports remain. (JUSB3/4 need additional confirmation)
- Replace your custom USBPorts.kext in ..OCKexts. Then put all files into ESP (EFI System Partition) and add Opencore.efi to the boot menu.
- Check your BIOS settings. Here’s something you care:
