12. Complete macOS installation. The system will automatically reboot (let it reboot on its own).
Step 2. First booting with macOS
We will NOT be using Multibeast!
Once the macOS installation is complete, it automatically reboots and the clover boot screen appears again.
Select the installed macOS and press Enter to display the High Sierra initial setting screen.
When the MacOS Welcome screen opens, choose your country. Press continue choose your keyboard. Press continue. Choose don’t transfer any information now. Press continue. Choose Don’t Sign In and press continue. After agreeing to terms, create name and password.
After completing the setup, you will replace the
EFI folder with the EFI folder attached below so that you can boot by yourself.
- Download Clover Configurator
- Open Clover Configurator.
- Mount EFI to mount the partition where macOS is installed.
- Open Partition, download the EFI folder and copy and paste it.
- Go to the EFI folder, then Clover and open config.plist with Clover Configurator. Choose SMBIOS and change the serial number (click Generate New. Check the serial number here to be sure it is not currently used.
- Save settings
- In the Clover, Configurator select Install/Update Clover and install the latest one.
- When installing the clover, click Customize and select the options as shown below.
- Install for UEFI booting only, Install Clover in the ESP, Dirver64UEFI>>EmuVariableUefi-64, OsxAptioFix2Drv-64, Install RC scripts on Target volume.
Step 4. Finishing up.
In the folder below, place the contents of “Go Sys Lib Ext Folder” into the Extensions folder in the system library.
Now you can boot to the hard disk where you installed macOS without booting to the USB drive. Enter the BIOS setup and change the boot order to [UEFI] MacOS installed disk to the priority boot.
After restart, you should be working fine. iTunes should not be crashing. Sleep/wake should be working.
