It looks like you have a Fusion drive setup there.

command-option-r boot back to Internet recovery (you should see the grey spinning globe first). Then in the Utilities menu open Terminal and run the command below. That should wipe and reset the Fusion drive. Then quit Terminal and reinstall the OS.

Code:
diskutil resetFusion

did that and here is what it said:

Okay... that is not Mojave.


Follow the instructions here for pre-Mojave a little further down the page.

I did everything it said, and took pictures of the process. But after doing it all, I got this message.

It looks like you got the Fusion rebuilt okay. I would just reboot back to Internet recovery and try the OS install again. It looks like something got corrupted in the download process.

I did that but just receive this, and then I click“Startup Disk” and it doesn’t show anything?

Confirm you are in command-option-r Internet recovery (you saw the spinning globe)?

Once there, click install macOS... does that then allow you to select the Macintosh HD Fusion drive as the install destination?

So if the first aid fails there is no way to recover data to an external drive so then you can fix it?

There are paid, third party drive recovery apps you can try if the data is really important. There are even companies you can pay to try and recover the data for you.

I'm not seeing anything wrong there. Once you have command-r booted to recovery can you not select that 499GB Macintosh HD volume as the install target?

I am having similar issues with my Mac book air this is my terminal screen . PLEASE HELP ME

Can you hold down command-option-r at startup to get to Internet recovery? After you select your wifi, you should see a spinning grey globe while the recovery utility downloads and starts.

Once that comes up, launch Disk Utility and erase the internal drive then reinstall the OS.

Up in post #21 you posted a picture that showed Macintosh HD as an install target. When you took that photo, were you booted to recovery (command-r boot)?


Hi!
I’am new to this forum. I seen what you have replied to other people, I’m hoping you can help me. I do not want to mess up my computer.

Hi, I just bought a used iMac today and found that the OS was wiped and the HD is locked. I need help unlocking it to reinstall High Sierra on it. It’s a 2010 11,3 iMac EMC: 2390

Try following my instructions in this post and let me know what happens.

so I just tried the internet recovery and it’s been sitting at this screen for over an hour. It hasn’t asked me to connect to a network. And I’m assuming that it’s not currently connected to one after restarting the system.

So I hooked it up to LAN, got the internet recovery mode to work and I formatted my HD to Mac OS extended (journaled). When I tried to reinstall High Sierra I got to this screen. Now whenever I restart the machine it goes to this same screen. Any ideas?
