This is a bit of a weird situation that I really hope someone can help with.
My wife's old MacBook Air 11" 2011 needed to be updated from 10.7 to Sierra.
I downloaded the installer and ran it. It promptly hit the "This installer is damaged error" but for some reason I couldn't access the Terminal from within the upgrading console because the Utilities menu was gone. I had hoped to be able to change the date and time to get rid of the error.
I rebooted and removed InstallInfo.plist from the Sierra installer's contents which was suggested could help.
This allowed the installer to run. However, after a while the installer stopped because "File system verify or repaired failed".
I tried to restart, hoping that I could go back to 10.7 because the installer hadn't come very far. It had only gone past the first 5-min part and then continued a few minutes into the long 30-minute installation sequence when it stopped.
But the computer is stuck in a reboot loop. It only goes into the Sierra installer upon restart and upon cold boot.
When the installer stopped the Utilities menu somehow appeared and let me access Terminal. I was hoping I could now copy over ~Documents to get a backup of some important stuff there.
Here's where it seems to get strange.
If I use diskutil list I see Macintosh HD listed as volume disk0s2 together with EFI and Recovery HD. I can also mount disk0s2.
But I am not able to see Macintosh HD if I go to /Volumes and use the ls command. Then only EFI, "Image Volume", Mc OS X Install DVD and OS X Base System appear.
Where has Macintosh HD gone and is there any way at all to access it in order to copy stuff from it?
Thanks heaps in advance
Philip
