hi my mac shut down during instlation and I keeps displaying this message that I have posted a photo of. I was advised to hold down Up,cmd, alt, shift, p, r to take me into macOS utilities. I then go onto disk utility and use first aid to see if there is any problems. I then click reinstall macOS to it then tell me there is no bag? But now it does not display this message and the install bar is stuck on 6 minutes. Please can anyone help?
