So I finally got high Sierra to boot up on my hard drive again (see here for that story), however it come up to the login screen and my username will not compute. (yes I am that guy who only has the main user and the guest account on there, Guest would not login either - I thought there was no password for that... hmmm). Tried my password nothing - tried every password I could have ever used - nothing. So I go into recovery to try to reset - no user accounts found. I was having trouble with the drive not mounting before - but hey it is loading osx so why the trouble now i think. Go to single user mode and the user is there when listing users - but when I try to reset password using command line it cannot seem to find it. I also tried to create a new admin account which failed - it said read access only and gave me an error code which I did not write down before crossing my fingers and rebooting - which led to the same old login screen Any suggestions? I have data backed up but not any of the settings or programs. I plan to utilize time machine if I can get back in.
