OS X :: Way To Change And Remove An Unknown Administrator Password
Sep 2, 2009
My partner purchased an older second hand Macbook (running Leopard - from what he tells me). But he can't get round the admin password which wasn't supplied to him. there any way to change/reset this password without knowing the current password? I've got a copy of the Leopard install disk
I bought a Macbook air on ebay & I do not have the password for the person listed as administrator. Is there a way to delete that administrator & set up myself as administrator?
When I go to system preferences and then groups and users, it is showing that a guest user has set up a profile. I did not set this up. My computer won't let me erase this user.  The "minus" symbol at the bottom of the tab is highlighted grey and my mouse can't select it. Also, the box that says "let this user administer this computer is checked and it won't let me uncheck it. Weird. What do I do?
Info: MacBook Pro (Retina, 15-inch, Late 2013), OS X Mavericks (10.9.5)
17 inch iMAC with OSX version 10.6.8. How do I delete that an unwanted computername? Spent hours and hours on finding an answer / solution. However, without succes. Under SHARED I see two lines featured as mac servers. One is <iMac van bouko witteveen> the other one is <Time Capsule MAIN>
I am giving my wife my MacBook Pro to replace her MacBook. I have been able to transfer documents, iTunes and photo's (thanks Terence Devlin) to my former MacBook Pro. I am now trying to make her the administrator. I have gone into system preferences and have not been able to proceed from there.
I just bought a used Emac running 10.3.9. The previous owner does not remember the administrator password nor did I realize how important it is to have. I have the original install discs and did boot using the disc. I then went under the install menu and chose reset password. I changed the user password but have been unsuccessful at changing the admin password. The drop down menu in password reset gave me the option of Administrator (root), Application, or finally user. I have read a couple of articles cautioning not to change or work with root changes.
A week ago, my computer (Macbook) "crashed". When I powered it up, it would go to the grey apple screen, then it would go to a blue screen, then it would switch to a light blue screen, then back to the darker blue screen, etc and never fully boot into OSX. I finally found my install discs for OSX and reinstalled my operating system from scratch, formatted my hard drive, and started new. Once I reinstalled, I realized how outdated and different everything looked... and I realized I was running OSX 10.4. So from there, I found my Leopard disc (10.5), put that in, and "Upgraded" my system to 10.5.
And basically here's where I'm at now:........................
After upgrading to Leopard, when I try to install or update any program on my computer it asks for the Administrator username and password. Well that should not be a problem seeing as how I am the administrator and so I type in my name and my password and it says "you must type an administrator's name and password to make changes to software update." So I went to system settings and checked and it no longer has my account as the administrator and I can't make any changes because I am not the administrator no more. After installing Leopard, this has happened. What should I do? (I am fairly new to Macs, I have had my Macbook about 3 months.) I also noticed that my Macbook (when I shut it) has started to wake itself up from sleep mode and stay that way while it's still closed.
I remember my adminstrator-name and password, but when i write it, it won't let me in and change something. - I know my password 100%, but how can i find my adminstrator-name?I always have been in it all. I knew my password. I still know. It did not ask me about my adminstrator-name before, but now it does. How can i find my adminstator name? I know i can reset it all with mac CD, but i don't want to delete all stuff in my mac. What shall i do?
I have a late Mac Book Pro 15 inch, and recently being asked for Administrator's Password, but will not accept any passwords I enter. An Administrator's Password is then required to change the Password. How do I reset the Administrator's Password?

How do I get a new Administrator password for my computer?I was trying to change the password on my computer. I have done this before under "System Preferences", then "Security and Privacy". So I entered my old password, and then entered the new one...twice as always and THEN I don't know what I did, but a window popped up that I didn't finish reading completely because as I was in a hurry I accidentally hit 'enter' and that did something.. now my computer does not accept my password. I've tried both the old and new one.
How do I reset my macbook pro administration password if I can't remember the password or inadvertently typed it incorrectly when updating my settings?
We had a HDD fail on one of our office Mac laptops (a power pc G4). Apple repaired it and I restored all files etc from a backup. I was the administrator during the restore. Before I could get back, the user changed that account to a standard account and changed the name. Now there is no way to change the account back, because there is no admin to authenticate the change. Anything I can do? I am not an advanced computer/Mac person.
I just restored my 13" Macbook Pro from a Time Machine Backup that was created on a 15" Macbook Pro via Migration Assistant, and I have been experiencing some weird problems. The weirdest thing is that I cannot change my account from Standard to Administrator, even if I am logged into the root account. When I authenticate and click on the check box that says "Allow User to Administer This Computer", the box goes blank again and a box shows up telling me a restart is needed.
i was trying to set up another account on my macbook but i made the new account the admin account with the parental guidance how do i change my original account back the administrator?
I have a imac running osc 10.6.8 I just found the disks, i received this as a gift from a relative who passed away I do not know the password. I want to change the admistrator of the computer without loosing all the programs.
I am a network administrator and an mac user. No one else is my IT dept knows anything about macs so I have been given the responsibility of managing our 5 or so Mac's in the company. I've been able to figure everything out fine, but I have one user that insists on turning on the screensaver password on his computer. Now on windows, you can unlock a computer using an administrator account but on mac this is not the case. I want to disable the option for the screensaver password but I do not know how. The user is a local administrator on the computer because that is needed for a few things but he is making it impossible for me to work on his computer because of the password. Also, I've tried telling him not to enable it but he seems to not care what I think.
I'm looking at buying a macbook. The seller does not have the administrator password or the original Leopard 10.5 discs. Will this cause a problem if I want to upgrade to Snow?
I recently purchased a Powerbook G4 on Ebay and I just received it today. I bought the newest OSX software to put on it but when I put the disc in the computer and click install it says I have to enter an administrator password. I have no idea what the password is! How do I go about reinstalling the OS without the password? I just simply want to clear everything and reset it. I am not a computer technical person and normally on a PC I just put the disc in the computer and restart it and it boots from the disc. I tried doing that with the Mac but it never starts up an installation when I turn the computer on with the disc in it. I looked on another website and someone said to restart it with the disc in and hold the apple button and the C button and the down button. I tried that a couple of times and nothing happened.
