Unknown administrator password ?!

Hi
I have just install Mac OS 10.7.3 and I did not set up administrator password.
I am trying to download and install some programs but when I am trying to installing programs the system asking to entire  administrator password to allow this for example "install adobe flash player wants to make changes. Type your password to allow this".
I hope find some solution
Thanks

Or you can reset the Password by using the password recovery tool. On Snow Leopard you can used it when you boot from the CD. In Lion you must boot the Recovery System by pressing cmd + R on startup.
then open the Terminal and write:
resetpassword
a new window will pop up and you can reset the password you lost.

  • Is there such a thing as a default administrator password?

    I've searched these forums & elsewhere but haven't seen anything quite like this. My parents' new iMac was set up by someone else several months ago & I am visiting them for the first time since.
    Things generally work OK but they find that occasionally they are prompted for a password to update the keyboard's firmware, for example, but then their administrator's password (which works otherwise for software updates) won't work for these prompts. In poking around their iMac I also discovered that some portions of System Preferences also seem to have a mystery password (unknown to any of us). For example, the security settings & the password settings can't be changed without this mystery password. I'm pretty sure that they didn't do anything or set a firmware password; I'm also pretty sure that the guy who set up their iMac wouldn't have done anything like this. He was pretty careful to leave printed out password & hint instructions for them. This is why I am wondering if there is some "factory default" administrator password or something that we've overlooked.
    Does fixing this require using the installation disk to reset the administrator password, or is there something else that I should be doing or looking for?
    Thanks so much for any advice you may have!

    First Enable the root user account:
    To enable the root user account:
    Open System Preferences and click Accounts.
    If the lock icon is locked, unlock it by clicking it and entering the name and password of an administrator.
    Click Login Options, then click Join or Edit.
    If you see an Edit button, your computer has at least one connection to a directory server.
    Click Open Directory Utility.
    Choose Edit > Enable Root User.
    Next:
    change the root user account password:
    Choose Edit > Change Root Password.
    When prompted, enter the new root password in the Password and Verify fields.
    Click OK.
    Next:
    Choose Edit > Disable Root User.
    Close directory Utility.
    If it won't allow you to execute the above instructions, then your account may not have
    any administrator privileges.

    Hi,
    I contacted SAP and they provide me a solution.
    It can be solved by deleted these two files : Ks and UAstate in \usr\sap\put\ua directory. After that, restart UaServer and provide a new password.
    I'm now confronted to a new problem.
    After giving to system the new admin password, i'm getting this error message from UA..

  • Prompting of Administrator Password When Installing New Software.

    I recently installed some software onto my Mac but I was not prompted to enter my administrator username and password as is usually the case (or so I thought).
    Does anybody have any ideas as to why an administrator password is not always required when installing new software? The reason I ask is that I thought that this was one of the protections offered by the Mac to prevent unknown installations of Malware etc.
    Thanks.

    No password will ever be requested when you simply use drag and drop to install an application in the Applications folder. This is because you are a member of the admin group, and the admin group has authorized access to the Applications folder.
    Nothing should install without your knowledge. If you are concerned about viruses and the like, then that's a different matter altogether from the question you asked. See this:
    Do You Need Anti-Virus Protection for Your Mac?
    According to Rich Mogull's article, Should Mac Users Run Antivirus Software?,
    "The reality is that today the Mac platform is relatively safe. There are hundreds of thousands of viruses and other malicious software programs floating around for Windows, but less than 200 are known to target the Mac, and many of those are aimed at versions of the Mac OS prior to Mac OS X (and thus have no effect on a modern Mac).
    It's not that Mac OS X is inherently more secure against viruses than current versions of Windows (although it was clearly more secure than Windows prior to XP SP2); the numerous vulnerabilities reported and patched in recent years are just as exploitable as their Windows equivalents. But most security experts agree that malicious software these days is driven by financial incentives, and it's far more profitable to target the most dominant platform."
    Mr. Mogull is a computer security expert. I recommend reading the entire article as it is quite informative.

  • Administrator Password Change

    Hi,
    After changing the default Administrator Password in the RPD, I ran the Cryptotools utility for both BI publisher and BI Scheduler to make sure that the BI Presentation services can identify the CredentialStore.
    There is another xml file, xmlp-server-config.xml in the OracleBIData\xmlp\xmp\admin\configuration folder, which has a property name "BI_SERVER_SECURITY_ADMIN_PASSWORD with its value being the default password for Administrator. The password here is in clear text, not encrypted. Is this how it's supposed to be?
    I do not see anywhere in the Docs. where there's an encryption procedure for this file.
    I certainly do not want to have this file with the password in clear text.
    Has anyone encountered this issue?

  • Bought Used macbook pro, don't have administrator password and don't have the OS disc. Is there a way I can reset or delete the password?

    I recently bought a used macbook pro. I can pretty much do everything I need on it until I want to change setting and such things. Then it asks me for an administrator password which I do not know or have. On top of that I do not have the OS disc either. Is there a way I can SAFELY reset or delete the password so I can set my own without the possibility of screwing thing up. LIke I said I can do most anything. I figured this out when attempting to tether it to my smartphone for internet access (I do all the time from my desktop but my desktop is a PC so things are a little different) I am a very new mac user, I have always been a devoted PC user until now. I have to say I am really loving my macbook pro I may just stick with mac from now on (if I can get this problem figured out without too much stress.
    I am looking for the safest and best way to fix this issue where nothing I do would mess up the laptop. I can use it now and I do not want that to change, I just want to be able to change my setting and set a password of my own. PLEASE HELP, THANX!

    Hi
    There actually is a slightly easier way in OS X 10.5 or greater.
    1. Start up in single-user mode (hold Command-S as the computer starts up).
    2. Type: mount -uw /
    3. Press Return.
    4. Type this:
    passwd (user's short name)
    Replace "(user's short name)" with the short name of the user account whose password you wish to reset. If you are not sure what the account name is, you can get a list of user names by typing: ls /Users
    5. Press Return.
    6. Enter a new user password.
    7. Press Return.
    8. Type: reboot
    9. Press Return.

    My Macbook was hacked by somebody right after activating downloaded VLC player.
    I couldn’t control my machine. Every thing was messed up! Finally after reboot I realized that even my administration password was changed. Stupid hint I was able to reed: What located in box above low case ? I used my friends computer and founded hot to fix my problem using Unix commands to reboot in a single user mode. I founded a lot of different solutions which had prity the same beginnings but very complicated continuation, which, I understood will force me to cach during restoration anuther crap – time bomb in my mac! Finaly I did restor. somehow. But still feel somebodyies presents. Safary messed up – I will send you a log Itunes – messed up. Speaker in a top menu – grayed, and I can’t control my volume. But the most triky thing – bouth my Apple keybords – internal and mostly bluetouth external also working and typing wired! I am sorry for my spelling, because I cant check spell for Mac’s Word (in Microsoft it was F7) I have also several attacks from my neighbors by community I know their names, because they are somethere very close to me – I can see them throuth FI-FI connection. They often kick-me out from my place and started to use my resaurces. And also Mackeeper make me a hard time!
    In Microsoft times u just reinstalled computer – clean installetion from corporate licensed disk. But now I am a beginner in MAC – I love it! But a lot of new and triky – at this way
    Fore example – my goal – to do fool Macbook backup at external USB drive using boot srartup option and make my life yaser in case of crash. But now, I don’t know if I can trust recommended program  Carbon copy cloner – Ms. Bombich?
    I am very sorry for my spelling, because I feel somebodies presents, who playin with me.
    Final question Do I need some antivirus Mac compatable which is update paches, service packs? How to map defolt documents folder not to a local, but to external USB?
    Esquse me for a lot of questions, but I am beginner in MAC, and I LOVE it!
    PS. Good news. Looks like Safari came back! Somebody, probably allredy helping!
    But my interface qute different from original – so something still wrong!

  • How to Reset Windows 7 Administrator Password on My Laptop

    I have windows 7 Home Premium and i forgot the administrator password. whenever i start the windows 7, it asks for the password to log in. unfortunately, i forgot it. what to do?
    I forgot the administrator's password. I'm not able to log in to windows. It says, "did you forgot the password?" whenever i try to log in. How do i reset forgotten Windows 7 admin password without losing data?

    In your
    your situation,you can recover your password form Safe Mode.Windows 7 system has a built-in administrator account that is created during Windows installation and disable by default, which has no password in it. You need to enable that account before forgetting
    your other admin account password. Otherwise your built-in administrator account won’t appear in the screen in this tip.
    Step 1: Start your win 7 computer and press “F8″ while the computer boots up. Scroll down to “Safe Mode with Command Prompt” with the arrow keys on the keyboard and press “Enter.” Your computer starts in Safe Mode with Command Prompt.
    Step 2: Select the Administrator account that appear in the screen, then enter command prompt. Type: net user ****** 123456 and enter (****** is the account name and 123456 is the new password), it will show you a message that” the command completed successfully.
    Step 3: Restart your win 7 computer, then you can log in as ****** with the password 123456. You can go to control Panel to change your account password if necessary.
    If this
    way doesn't work you can try a tool named Windows Password Recovery Tool Ultimate. 

  • I have a macbook latest update & am trying to install flash player 7 will not accept password & I have triesd both administrator password & adobe password & "ok" keeps jumping w/o any message other than hint: black & white" I'm confused & frustrated.

    I am a macbook user latest update & cannot get beyond the password - have used Adobe password & administrator password but the "ok" keeps jumping - hint: says "black & white" Very frustrating.

    This password prompt is presented by your operating system, and is intended to keep you from accidentally installing software.
    If this is your personal machine and you don't need a password to log into the computer when it first starts up, you can probably leave the password blank and click OK to get past this prompt.  If this is your personal machine and your normal password isn't working, check to make sure that CAPS LOCK is off, and type the password carefully.
    If this is your work machine and it's asking for an Administrator password, well, you'll need to have a conversation with your friendly IT person.
    If you're still stumped, you may need to reset the password on your Mac:

    I have an older version of iTunes on my office computer and it will not allow me to upgrade to the newer version without an administrative password. How can I get around this???

    If you have an iBook G4, (PPC) you can't do much.
    But if that is a MacBook (intel) you may be able to
    upgrade the OS X, if the hardware is up to it...
    Since there were about nine different build models
    of MacBook (not powerpc iBook) to identify what
    one you have would be the first step to knowing
    what OS X and RAM upgrades it could use.
    If the computer is not already at OS X 10.6.8,
    it can't go online to get or use OS X 10.7.5. So,
    when you more accurately describe the 'Book,
    detailed information is available.
    When you find the serial number, there is a web
    page that can be used to identify by serial no.
    http://www.powerbookmedic.com/identify-mac-serial.php
    That'd be a first step. Or even the Model number
    which should be visible on the outer case by hinge.
    Good luck & happy computing!

  • Can I use the same administrator password on multiple devices

  • Resetting a forgotten Administrator Password

    I'm helping a friend who has an iMAC G5 which currently runs Mac OS X 10.4.8, (Tiger), and has forgotten his administrator password. The original discs for this machine are Tiger Mac OS X 10.2.3. We've already tried using the install disc (disc 1). We put the disc in and restarted the system, holding down the C key when the tone was heard and continued to hold it until the spinning gear appeared. It seems to load the CD because we could hear it grind as the system started up and we noticed small file-folder icons appear in the center of the screen with a question mark, but eventually it seemed to load the OS from teh hard drive and started as usual, with a Finder window open browsing the CD. From everything we've read, we should have instead seen the installation program where we'd have the chance to reset the administrator password. Can anyone offer some advice? Thanks!

    Hi LLApple, and a warm welcome to the forums!
    Yes, you should've sen the Installer, but...
    I wouldn't try changing Tiger's Passwords with a Jaguar or Panther Install Disk at all.
