Running OSX Mavericks on Macbook Air SDD disk.
The system has corrupted the password file so none of my six identities can log in - password invalid.
Following discussions and tests with apple support,
1: Boot into safe mode does not work 2: Boot into single user does not work 3: I cannot try target mode as I do not have a second mac, but will investigate this possibility further
4: Boot into recovery mode does work
Q1: If I take the OSX reinstall does it leave my data alone, and ONLY reinstalls the OSX? I have a backup but it is not as uptodate as I would like.
Q2: Is there anyother way of doing a reinstall or alternatively saving data before reinstalling the OSX?
Q3: If I take the terminal option, I get the -bash-3.2# prompt. At this point, Applesupport asked me to enter resetpassword. BUT on typing r , bash immediately changes the prompt to (reverse-i-search)`':
Is there anyway to get bash to accept normal characters and turn the intelligent search off
Q4: Does anyone know the filename and path that is corrupted as I might be able to restore and old one?
