password
I did some software updates and restarted my 13" Macbook Pro (2011 ish), which I have done many times before. However, I seem to have forgotten my password and I cant login. I am about 97% positive that it is the same password I have used dozens of times, and matches perfectly to my hint, but its not working. Is there any reason a current password would just stop working? anything I could have done while using the computer that could have affected this? I am so confused.
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.5)
