I was playing a game on Steam and my Mac crashed. I’m a noob and a fool and I have no back up.
It wont boot and I getting the flashing question mark, in recovery mode I cannot install a fresh OS X as there is no disk listed on install.
When I run diskutil list in Terminal, only the bases system appears.
I would be hugely appreciative, of any advice at all on getting the machine to run again? (and hopefully with data somehow retrieved… I know…)
