Hi, I hope someone can please kindly help me. I updated my 2014 Macbook Air to Mojave recently. I used it for a few minutes, after that I shut it down, went on holidays and a week later when started it up again I got the prohibition symbol. I tried reinstalling OS trough internet recovery, ( the only recovery option that happens to start) and tried reinstall from time capsule backup as well . Neither of them works because as soon as I get to the point of unlocking the hard drive I can not type in the password as the password bar is not responding to anything. I can't click into it, and can't navigate into it with the arrrows either. I don't think it is a keyboard problem as I can type in the network password for the wifi to start reinstall trough internet recovery and I can also see the cursor arrow moving around when I circle my finger on the trackpad. I also opened disk utility to see if I can run a first aid on the HD but the Macinthos HD icon is grey and it says it is not mounted. Is this connected to my original problem that I can not type in the password and if yes is there any way to get around it without losing my data? My time capsule backup is older than it should be and a few of my documents I'd love to keep are not on it so I would prefer to do it without totally erasing my Mac if at all avoidable... Thank you in advance for all your responses!
