Admin account Deleted

Hello, I control a network of Macs remotely. There all new iMacs running OSX 10.6.5.
In the ARD list the computer displays ACCESS DENIED. I know the password, so I tried to verify it and no joy. I then tried to SSH in as admin and nothing. I then SSHd in as root and the admin account had gone, completely deleted. After re-creating the account and enabling ARD client all was back to normal. But please, why is this happening? This is the log from it:

  • Deleting Admin Accounts + Erasing HD

    I'm giving away a MacBook (2.1 GHz Intel Core 2 Duo) running 10.5.8 and I want to delete the two admin accounts, delete all the files (including media) and erase the hard drive.
    Can a "standard" account delete an admin account? Where should I begin?
    Thanks!

    Throw away any files which may contain sensitive data, securely empty the Trash, insert its original disk, restart the computer with the C key held down, use the Disk Utility to erase the partition with Mac OS X installed, and then install a new OS onto it. Include the disk with it.

  • Multiple admin accounts, need to delete one of them ... what happens?

    Ok, short story shorter - broke up with my GF and she has an account on my laptop.
    She has saved all her stuff, so I'm not worried about loosing personal files/documents.
    My question is though, what else may be lost that I should be careful of.
    • Will programs be lost?
    I installed Adobe Suite through her account, will that be removed as well? That's an application though, that I set for 'all users'.
    • Will there be any change to system, or cause errors if that was the main Admin account?
    By deleting an Admin that was in use 50% of the time, are there any system problems that may happen after I delete?
    From what I remember, the system when I created another Admin account it just treated it as if someone just set up their MBP for the first time - ie. they seem to be completely independant.
    Basically, I just want to make sure my experience (in my account) does not change once I've pressed the delete button.
    Much thanks in advance.
    -NTFW

    Thanks andyBall_uk,
    I can confirm that there are no files/data/passwords that I'm concerned about loosing on the account I want to delete.
    *BUT, on the account I want to delete - I installed Adobe Illustrator/Photoshop.
    These programs are usable on my account as well, I see them in my Application folder even though I only installed it once.
    Are you saying it will delete Adobe Illustrator/Photoshop because it was installed on that Admin account?
    Thanks very much for the help!

  • Can I delete all files and users (including admin account) without re-installing SL?

    I have a 1st generation Macbook Air, running Snow Leopard 10.6.8.  Just bought myself a new MBA, want to sell the old one (privately, not soliciting here).
    The original install disks were Leopard.  I bought a family pack SL and upgraded the MBA at that point.  Earlier this year I sold my old Mac Mini (when I upgraded) and included the SL install disks with that sale (stupid of me).
    Now I want to sell the old MBA.  Ideally, I'd have a clean install on SL on it, minus all previous files and accounts.  I've done that before when selling old computers, reformatted / erased the HD, then reinstalled the OS.  But I don't have the SL disk anymore, and I don't really want to pay for it just to prep this notebook for sale.
    AFAICT, my options are:
    wipe the HD and reinstall Leopard (the only OSX disks I have).  Whoever buys it from me would need to upgrade to SL themselves, and from there to Lion if they want.
    somehow try to delete all files and users without touching the current install of SL.  I'm not terribly worried about security of what little information is on the MBA (nothing important to me), so I don't mind trashing files and then emptying trash instead of wiping the HD block by block. 
    Any ideas for how to do #2?  I can trash all files/folders under /user, uninstall all applications and delete their folders from Library, uninstall all browsers except Safari and wipe the history from that...
    Is there other stuff I should be deleting?  plist files, maybe?  I'm leery of messing around too much and disrupting the install of the underlying OS.
    Can I also delete the admin account (or rename it "admin" with a generic default password?)?
    Any other suggestions?  Thanks.

    Trashing files you have created is relatively easy. Getting rid of an account is a bit harder. Trashing the .plist files, etc., that may contain personal info is a lot harder, and there is always the risk that you will miss something.
    Best, and easiest, and customary, is to do option #1 - wipe the drive and re-install the original OS from the original disk set. The receiver of the machine can then decide which OS they want to upgrade it to, and purchse accordingly.
    The original disk set for that machine should be included with it when it is sold.

  • I have chosen to fil migrate from old ibook to new MacBook Pro using Time Machine after establishing admin account. I now have two admin. accounts and wish to delete the later one and transfer files manually. I am worried I will loose both accounts. ??

    I have chosen to fil migrate from old ibook to new MacBook Pro using Time Machine after establishing admin account. I now have two admin. accounts and wish to delete the later one and transfer files manually. I am worried I will loose both accounts. ??

    Use the Office for Mac and ignore using Parallels for that. If you have PC only apps you have to run that are MS Windows only then consider Parallels. Just transfer your main PC, using Migration Assistant.  If you don't know how then simply read over Pondini's article called Lion or Mountain Lion Setup Assistant tips and look for the section on migrating from a PC. Millions have done what you are about to, it's far from leading edge these days, if you go to an Apple Store to purchase they will offer this as a service, something you might be interested in.

  • Can i delete my admin account and make a new one?

    i want to start a new account cos i have so much rubbish on my current one. i have worked out how to make new accounts but cant work out how to delete my main (current) admin account?
    any help would be great. thanks.

    Create a new account with Admin privileges.
    Backup important files (Documents, Music, etc).
    Log out of current account.
    Log into new admin account.
    When you are sure you have backed up and moved everything over, you can then delete the old previous admin account. You can have more than one admin account so it's not necessary to delete immediately. Actually, it's not a bad idea to have another backup admin account for troubleshooting purposes.
    Be advised though that you'll have to have separate names for each account.

  • How to delete admin account and keep my original account (that is now being listed as standard or managed)?

    I created another account using parental controls and somehow that new account is managing my first original one. The new account is being listed as admin in Users & Groups. When I logged into my original account, I go on Users & Groups to delete that admin account and the little minus - sign is greyed out. 
    Also I need to add that before I do all that, I go on the padlock button and I have to enter that new account's username and password/. I am so lost!!

    Did you ever find an answer cuz I am curious too!

  • How to delete one of the two admin accounts on my Mac

    When I migrated from a ppc to OSX I found that I have 2 admin accounts. One from the old computer. I want to delete the old account but am afraid
    That action will do a lot of harm

    Ensure that account's not currently logged in, open the Users & Groups pane of System Preferences, unlock the pane, select it, and press the - button.

  • Two Admin Accounts - How to delete one?

    Hi All
    In fixing another problem I have ended up with two Admin accounts. One is my main admin account and the other a short term fix.
    Trouble is I can't delete the second admin account from any account. When I try to delete the second account the 'minus' sign is greyed out - even when the second admin account is logged out.
    Any suggestions???

    It is generally recommended by most experts to maintain two admin accounts, so that if something goes wrong with the primary one, you have another to use to fix things with. If I were you, I'd just leave the second account.

  • Can't delete admin account even as Root

    We're experimenting with integrating our Mac users into Active Directory. I've read that you should delete the user account in Sys Prefs first and leave the home folder.
    The problem we're having is that I can't delete the users account in system prefs even if I log in as the root user. I get a generic error after about 10 minutes of looking like it is working that says the account could not be deleted.
    My guess is it has something to do with the fact that I had already logged into the same acount with an Active Directory login and the permissions have been changed on certain files and now it can't complete archiving the home folder because of some rights issue.
    I have unbound the computer from the AD forest and ran disk permissions to no avail. I'd like to keep the existing home folder to use with the network login if possible so I haven't tried the quick delete option.
    Any advice would be greatly appreciated.
    Thanks

    You can't delete an account if it is logged in, or if it is the only admin account on the system. So make sure that there is at least one other admin account, and that the account you want to delete os logged out.

  • How long does it take to delete admin account on iMac and creating a disk image

    I recently upgraded to a new iMac. In the process, I used Migration Assistant to transfer data, network settings and user accounts from my old iMac. I ended up with two admin accounts. I reset permissions and began the process of deleting the second admin account. It seems to be taking a long time. How long does this process typically take?

    Depends on how much stuff there was in the account, but shouldn't be too long. Rather than muck with all of that, IMO, it's better to erase the new machine, reinstall the OS, and on first boot, use the Setup Assistant, as described in Pondini's Setup New Mac guide, to do the migration. That does the job correctly and doesn't muck up the system with that new admin account.

  • Just bought a second hand MacPro early 2008 running Mavericks. How do I reset it to standard deleting previous owner admin account?

    Just bought a second hand MacPro early 2008 running Mavericks. How do I reset it to standard, deleting previous owner admin account?
    The previous owner seems to have cleared most of his stuff but I can't make changes as it's asking for the admin password!
    Is there a way to reset the MacPro back as if I was logging on for the first time so that I can set it up as my computer?

    The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
    How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number onthis page. Then find the model on this page to see what OS version was originally installed.
    It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
    1. If you don't own another Mac
    a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from theApple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
    b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
    2. If you do own another Mac
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    3. Partition and install OS X
    a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
    b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the  Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
    c. An unusual problem may arise if all the following conditions apply:
              OS X 10.7 or later was installed by the previous owner
              The startup volume was encrypted with FileVault
              You're booted in Recovery mode (that is, not from a 10.6 installation disc)
    In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
    d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
    4. Other issues
    a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
    b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
    c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

  • How to delete current owner/admin account and create a new owner/admin acct

    I am the owner and only user of my G5. I've owned it since 2007 when it was new.
    I need to delete my current account and establish a new owner/admin account. When completed the new owner/admin account should be the only account on the machine.
    Can anyone offer some help.
    Thanks

    Here's the deal..
    I own a software titled "Kinemac". It's a 3D animation software which creates QT movies to import into Final Cut Pro. I've had the software since last April and about a month ago, all of a sudden, the program would no longer open. I contacted Kinemac's Support. They said my computer had apparently been "banned" by the software. (Maybe it saw the computer as trying to pirate the program.?????)
    I tried downloading a new copy of the software, reinstalled, entered serial#, etc. and still would not open. There was no crash. It just would not open.
    Kinemac said its only way to correct the problem was to enter into a screen share with iChat. I tried for 20 minutes with them to establish screen share with no luck. We could "chat" but not screen share. So, I came to the Apple Discussions pages on iChat and spent about an hour with a Discussions' User on iChat with NO luck there either. I gave up on iChat. Not certain I wanted someone unknown on a screen share anyway.
    Which brings us to this point. Kinemac says I can also add a new Admin Acct. Delete the current Admin and then rename the new user with the old user's name. I frankly don't want to mess around doing that but apparently there's alternative for Kinemac. So that's why I'm seeking info on how to do it. I really like the software and want to rectify the situation.
    Hope this explains the situation. Thanks.

  • Creating new admin account and deleting old one

    I am handing my MacbBook Pro to my wife
    I am thinking about deleting my account (which is an admin, of course). I made her an admin account and she has access to all my apps when she logs in...
    I WANT her to have access to my applications as if they were hers even when my account is deleted (e.g. Adobe CS3, Skype, etc.).
    My Question:
    When I delete my admin account (with which the applications were installed), will she automatically not have access to the apps in the "applications folder" anymore? In other words, when I delete the admin account with which the application where installed, do all applications and setting from that account get deleted as well from all other users?
    Thank you.
    (transfering, sync'ing, etc. can be so easy but such a headache from a personal standpoint: managing changes)

    So, this would create her a new admin account but:
    1. my old account folder will be there but without being associated with a user
    2. same for her old folder
    3. all I have to do is drag her old account's application folder + application support folder onto her new admin account and all applications would run like we never even even left her old account behind?
    Will any Leopard boot CD work or does it have to be one made specifically with her computer (it didn't come with a boot CD)...
    thanks...

  • Is it possible to delete the original Admin Account, having set up other Admin Accounts on the computer?

    Is it possible to delete the original Admin Account, having set up other Admin Accounts on the computer?
    Thanks,
    iHope

    Once you have an additional Admin Account, there should be nothing "magical" about the original Admin account.
    The Account you use to delete the original MUST be an Admin Account, or the old account cannot be deleted. But that is the "Acid test" for the veracity of the new Admin account.
