Now, you can click the mac icon -> Restart menu item on the top left corner to restart the mac to make the changes take effect.Introduced first with macOS El Capitan, System Integrity Protection is designed to protect a Mac from malicious software.Then input the command csrutil enable to turn on SIP, or input the command csrutil disable to turn off SIP.Now it may come to the macOS Utilities window, click the Utilities -> Terminal menu item.Open a terminal and run the command sudo nvram recovery-boot-mode=unused & sudo shutdown -r now to restart the macOS virtual machine and go to the recovery mode.If you meet such conditions, you can restart your macOS virtual machine and go to the macOS screen as normal.And when you run the dir command, there is only one kernelcore file in it.But you may encounter the error message like cd: ‘FS2:\’ is not a directory.Then run the command cd to go to the recovery boot image directory.Run the command FS2:, this will bring you to the FS2 interactive shell.Press the ESC key immediately, and then you will stay at the EFI Internal Shell console.In the Boot Manager window, select the EFI Internal Shell menu and press the Enter key to go to the UEFI Interactive Shell console.
