Likely dumb question, but I am also amateurish when it comes to electronics. When opening Mac, it asks for password. I've had couple of times recently issues of first time typing password and it won't work. Typed second time right away and it was okay. So, was it just me being tired and messing up long string of letters and numbers or could it be sign enemy was inside first time and then quickly let me log in twice, sensing I was coming?
