    I have a macbook pro and have a password for my user account. I only have one user plus guest that I never use it.
    I know my password by heart of course and have used it regularly many times a day.

    Last night I came to wake up my laptop from sleep and put in my password. And password failed. It said that either username or Password is wrong. Username always comes on its own (and it was correct) and I just put in password. So, I checked if the capslock was on, and it wasn't. I tried my pass a few times. I even hard reboot my laptop and it still didn't let me in. I was panicked as I thought my laptop might be hacked in and the password is changed on me.
    So, I managed to hack in my computer and sign in with a new admin account to get into it and also get into my old user account.

    Nothing seems a problem since then, but I have this concern that why I should be locked out in the first place, second if there is any threat or virus on my mac.
    And If so, how can I know?

    Your answers are really appreciated :)

    There's no virus on your Mac. What version of OS X are you running?

    Mac OS X 10.6.8
    Good news to hear there is no virus :) But how are you sure?

    There are currently no viruses for Mac OS X in public circulation, only a handful of trojans and other malware, which have to be installed manually via entering the administrator password.
    The only anti-virus you need to protect your Mac is education and common sense.
    Also know, that the term "virus" is often used to refer to other kinds of malware, but there are differences, which you can find out by reading the following:

    Okay. Boot from your Snow Leopard install disc by holding the option key at startup until you come to a selection screen and choose the SL disc. There is a password reset utility that will allow you to change your account password.

    This is also good to know, thanks. I can't remember any incident that something wants to download and asks for my password other than adobe acrobat that keeps coming to update and asks me for pass and it fails to update at the end. I haven't had a chance to figure out why it fails. But I guess that is a different story.

    Do you have any idea why the login didn't take my password? Any logical explanation for it? Or did I do something wrong that I wasn't aware of it.


    I don't have any problem with the password now, It is set OK and working.But thanks for the tip :)

    Glad you got it worked out. I honestly don't know what would've caused the issue. Maybe you had caps lock on or something? No idea.

    No. No caps lock issue!
    Is there another key or hot key that changes the keyboards characters other than shift and caps lock?

    Because none exist.

    Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 10 years ago. You cannot infect your Mac simply by visiting a website, unzipping a file, opening an email attachment or joining a network. The only malware in the wild that can affect Mac OS X is a handful of trojans, which cannot infect your Mac unless you actively install them, and they can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.

    Hi, the same problem just accrued on my friends computer. Her mac asks for password and it only says it is the wrong one, but it's not. And since we are currently in China she is not that happy with the thought of going to a computer store and try to explain this to some one that can't speak English... How did you manage to hack your way past this problem? Would really appreciate your help! Thanks

    Not wanting to be the prophet of doom and all that, however giving the details of how to unlock OS X systems to those that are unable to access their own computers across the public domain may not be the most prudent of actions.

    Take the Mac to an Apple Store or authorised retailer, they can reset the system, this is Apple`s advice and for obvious reasons. I dont care dwell on some of the negative aspects of humanity, then again I have no intention of giving them any advice on how to make good out of it ;)

    Had the same problem this morning. Thankfully a hard restart of the MBP resolved this.... Still looking into this issue as it doesn't make any sense why this would happen.

    If it's a 2016 or 2017 there may be due cause.

    High Sierra install wanted me to set a new password separate from icloud. Which I did. But for some reason it reverted back to the iCloud password and it forgot all my mail / iCloud account passwords under settings to boot!

    Weird right.
