Question about Apple MacBook Pro PC Notebook

Open Question

Screen has blue tint and the computer is making a wierd noise

I was not able to login with my regular username and password. I had to go through a dos based section to be able to add a user as the install cd change password utility did not work. During the setup for a new user the computer would not take my MAC security login for my router but it did take the security password for a pc which was totally strange because the system was set up before using the MAC security login.

Once in the was a prompt for updates. So I decided to let the computer install the updates. After about five minutes of installing the updates the screen changed and went weird. Hard to read and there was a blue tint and very pixilated. I tried rebooting the computer but that has not helped.

    It is a MAC OS X 10.4.6

    Originally only one. But the password stopped working. I did a search and found that if you put the install cd in and hold the option's button down you can go to utilities to reset the password. I did that but the new password would not work at all

    When the password reset did not work I found the option to hold the control and s button down to go to a dos based part and be able to add a user. I added one user and password and restarted the system as the directions stated. I was able to get in and it seemed to work fine until I started running the updates. The first update was a java update and in the middle of that one the screen went all weird. I finished running the updates and did two different virus checkers and a malware/spyware checker. All came up negative. So I added my daughter as a user to test the system and her login seems to be fine.

    How many users are configured for the PC? Is it checked regularly for viruses and rootkits? What type of OS is installed?

SOURCE: I forgot my Administrator Password

Basically you need to insert the first restore disc and restart your computer, when you hear the sound of it booting up press the C key and hold it down till you see the apple symbol, it may take awhile for it to start up don't worry. When the first window pops up, select english. Then the next window will pop up and then don't do anything with that window, but at the top of the finder click utilities tab and then password reset. Select the account that you want to change and enter the blanks then click the save button. After doing so the blanks should be blank again, now at the top of the finder click the password tab and click quit. Once you have done that at the top tabs again you should see an installer one, click that and select quit. Then restart. Thanks!

Take the start up disk for the computer and start from it, once the installer screen comes up hit continue and look in the menu items for a option to reset the password.  Select it and then you will be able to change the password on all the users on the computer.

SOURCE: Who is my computer's "Administrator"? How can I change it?

Hi Kaites33,
To create a Administrator account on your MacBook, follow the instructions below, however, please note that this will only work if "Open Firmware Password Protection" has NOT been enabled. Anyhow, it's worth a try.
1. Shutdown your MacBook. 2. Press the power button to start the computer. 3. Immediately press and hold the Command (Apple) Key and the "s" key, until you see white text appear on a black screen. 4. At the prompt, type the following commands, hitting "Return" after each.

  • mount -uw /
  • rm /var/db/.AppleSetupDone
  • reboot
  • --------------- Once your computer reboots, it will show the "Welcome to OS X" video, and guide you through the process of creating a new Admin User.
    Your current Standard User account will not be changed/harmed.
    During the creation of the new Admin account, remember to: a) select "DO NOT TRANSFER MY DATA". b) Keep the SAME computer name. c) Choose a DIFFERENT Username (Otherwise it will overwrite your old account)
    Once you have finished, you will have two accounts, and will be able to log in to either.
    Optionally, when you are logged in with the new Admin Account, you could change your existing account to an admin account, then log out, log in to the old account (which is now an admin account too) and then delete the new admin account.
    Hope this helps, and let me know if there is anything you do not understand.
    Regards,
    Cybernanga

    My apple laptop MacBook 13 has a message on the screen that is prompting me to enter a username and password. I have never set up a username and password so how do i bypass that page? or what can i enter...


    Apparently someone gained access to your Macbook and enabled the password login feature of the operating system.
    The login window that is displayed has a button for "Forgot Password". Click this button to see whether the person that set the password lock provided a cute hint for the password.

    If they did not provide a hint, I would question anyone that has recently had the opportunity to access your Macbook to see whether they set the password lock. They would have the password.

    When it 1st comes on it says enter current password


    You can do this without the Mac OS X install DVD, but be advised that doing this will trash any saved passwords in your Mac OS keychain.
    1. Power one your Mac and while the computer is starting, hold down "Command-S" until you see text scrolling through the window. This boots the computer into single user mode.
    2. At the Localhost% prompt type:/sbin/mount -uw /
      /sbin/SystemStarterYou will then see various services starting up.

    3. When the Localhost% prompt reappears, type:passwd USERNAME (where USERNAME is the username you login with)It will then ask you to type the new password twice, so do so.

    4. After entering the new password, type:reboot

    I forgot my username on my mac login, and I cant login? please helf me out


    If you have a Mac OSX install disk you can actually reset the password without losing all of your info on the computer. This should also help you with your username: With your MacBook on, insert the disk. When the popup comes to the screen asking if you want to install just CLOSE out of that box. Now turn your laptop off. Next, power it back on & as soon as you hear the 'chime' **HOLD DOWN THE OPTION BUTTON** or it won't work. It will say 'Preparing Installation' so you'll have to wait for a bit. **IMPORTANT** when that's finished, you'll see a Welcome window. Look at the VERY TOP of your screen and click on UTILITIES. In the drop down menu click on RESET PASSWORD. It will give you the option to click on your MacBook Hard Drive and other options. Only click on the MACBOOK HARD DRIVE (or Macintosh HD). below that it will allow you to choose the user that you want to change the password for (this should include the username). Type in any password you like twice then a password hint then click save. This will allow you to get into the profile. hope this helps. Don't forget to vote if it did!

    It sounds like it thinks you're typing the wrong password. Is Caps Lock on? Are you sure you're typing the right password?

    When you turn the macbook on it asks for a username and password and i recently changed it and didnt write it down is there anyway of getting passed it


    Did you choose a security question? (helps recover password)

    OR Try This (taken from another forum)

    "Try this
    Although there's no real way to recover a lost root password, you can change the root password even if you do not know the current one. You must have physical access to the machine in order to accomplish this task.

    Click Restart at the login window
    While the computer is restarting, hold down "Command-S" until you see text scrolling through the window.
    This boots the computer into single user mode.

    At the Localhost% prompt type:
    /sbin/mount -uw //sbin/SystemStarter

    You will then see various services starting up.

    When the Localhost% prompt reappears, type:
    passwd root

    It will then ask you to type the new root password twice, so do so.

    After entering the new password, type:
    reboot

    At the login window, enter username root wih the new password.

    Once you are connected, you can use the Multiple Users application (/Applications/Utilities) to change your normal user's password, or create a new user account."

    Try using no password by leaving it blank. If that does not work then boot from your OSX install disk and reset the password from the menubar.

    Setting a Password


    Under the extreme left of the tool bar, find the blue apple.
    Under that, choose "System Preferences"
    Choose "Security"
    Click in the circle that says "require password to wake..."

    When you installed OSX, you will have created a Username and Password. That will be the password you will use to get past the screensaver, if set, or a blank screen if not.
