I have a Macbook Air. This morning, I could log into my account using a password at start-up. Now I can't - it gives me an error message. This is the administrator account; the other account's password doesn't work either. What to do?
So when you start your laptop, you get a password request. I type in my password and it gives me an error. I am confident that I have not updated my computer or changed my password.
What gives? Is this a hardware problem? Can I fix it? Is it some fiendishly clever bit of remote hacking? (I assume not?) It's been months since I've used my laptop anywhere but on my home wireless which is password-protected.
