I am going to go mad this is the second time that it is happened and i really can't take it anymore.
Okay here the deal. I turn my macbook on everything is normally until, the login screen appears, instantly disappears and then goes straight into Darwin.
And the problem does not stop there, root user is disabled so, it won't even let me carry out some basic Darwin operation because me status (btw i am a administrator, THE ONLY ONE)
i went to the mac store before and they fixed it, by basically booting it from a external and then using the tinker-tool to make hidden files visible, AND THEN, going into the net info "Registry files" and then inserting the text .old in one of the folder.
Okay that cool its fixed for about a day until it all happens again, causing me soo much grief,
Can some one tell me please what the HELL the problem is!!!!!!
