Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
What version of Mac OS X are you using on that Mac ?
We're going to boot your Mac to a special mode called Single User Mode. Then type some commands/texts there which will force your Mac to bring the new account setup screen. So you can setup a brand new admin account for yourself. This might seem a little difficult, but it is actually easy.
Follow the steps below to create a new User Account in Single User Mode.
• Turn off/Shut down your Mac.
• Turn it on and immediately hold down the Command(Apple) and S keys together for 10 seconds to boot into Single User Mode
• When you see the text prompt (Single User Mode), type in the following terminal commands to create a brand new Admininstrator account (hitting return after each line). Also, note down the spaces between the commands, like a space between mount and -, space between -uw and / etc
mount -uw /
shutdown -h now
(If it returns any errors, then you are entering the commands incorrectly. Make sure you enter it correctly)
When you enter last command and press return, the Mac will shutdown. So turn it on, you should be able to create a brand new Administrator account.
If you want to change the password ***** old account, you can do that using the new admin account. On the new account, go to System Preferences > Accounts (or Users & Groups). Unlock the lock there. Then select the old account and click Reset Password. Then reset the password.
After that logout from Apple menu and login to old account. Now you may be asked for keychain thing. So click create new keychain and reset keychain database. Follow the steps below;
Open Keychain Access, which is in the Utilities folder within the Applications folder.
From the Keychain Access menu, choose Preferences.
Click General, then click Reset My Default Keychain.
Authenticate with your account login password (the password ***** reset earlier).
Quit Keychain Access.
If you have any difficulty on following the steps above, please let me know and I will continue to help you.
If you are using 10.7 or later version of OS X, then you can reset the password ***** booting into Mac OS X Utilities screen. Follow the steps below;
Turn off your Mac.
Turn it back on and immediately hold down Command and R keys at same time for 10 seconds.
This will boot your Mac to "Mac OS X Utilities” menu.
Click on the “Utilities” menu in top and select “Terminal".
Type (without space) : resetpassword
Press return. Select the hard disk, select the user account, confirm the user account and then change password ***** reboot as normal.
After restarting, if you get any message about Keychain then reset the keychain access database. Follow the steps below to reset Keychain;
Please let me know if that didn't work, so we can continue troubleshooting.
Oliver, I tried to accept the call offer. But it said your payment didn't clear. So I will help you here and I will walk you through the steps.
What version of Mac OS X are you using ?
To know the version of Mac OS X you are using on that Mac, click on the Apple icon and select About This Mac. You will see the version number there. Let me know the version and we can do this step by step.
Please type your reply in the box and hit Send to send it to me.
You can can reset it using the following method.
Click on the “Utilities” menu in top bat and select “Terminal".
Press return. Select the hard disk at top column, select the user account, confirm the user account and then change password ***** reboot as normal.
After restart, if asked for Keychain select Create new keychain button.
Let me know once you did that, so we can move to next step.
If you are in Reset Password ***** then select Macintosh HD at the top and do you see the user account on the drop down menu under it ?
That is because you didn't select the correct volume. Click the one with hard disk icon (which would be Macintosh HD). After selecting Macintosh HD, you should see the User accounts under the select user account. Don't you see it now ?
Yes, that is the hard disk. Select it. Now do you see the user account
There might be a problem with resetting the password ***** an encrypted disk. It sounds like your dad had enabled File Vault on it (advanced security). But try to reset the password. What happens ?
I assume you don't know his Master or File Vault password. Right ?
That Master password ***** asked is different from the admin password ***** use to install apps. If you don't know it, then you have to wipe out the hard disk completely and install a fresh OS X.
You are not in correct screen. Restart and immediately hold down Command and R keys at same time for 10 seconds.
Does it open the Reset Password ***** ?
The reason you are having difficulty is that, I believe your dad has enabled File Vault (high level encryption) on the hard disk. When File Vault or encryption is enabled, no one will be able to modify the hard drive. That is why the Single User Mode (first method) didn't work.
We may need to completely wipe out the hard disk and install a fresh OS X. Is it OK with you ?
It is not that easy to erase an encrypted volume. Direct erasing with Disk Utility will not work. We have to erase it via Terminal.
If anything goes wrong, your system will not boot until you correctly erase it and install OS X. Also, you need an high speed internet connection to download the OS X from Apple.
Before erasing, backup all your important files to an external hard drive and let me know.
Ok, will send you the instructions.
Erasing the HD and installing a fresh OS X makes you the owner and you will have full control over it. If anything goes wrong, this will the OS X non bootable and you will have to take it to the Apple Store to reinstall the OS X. This will not do any damages to the hardware components.
If you are in OS X Utilties screen now, then click on Utilities menu at the top bar and select Terminal.
Type the following and press return
diskutil cs list
It will show some list of drives. Copy the UUID of Logical Volume Family.
Then type the following and press return
diskutil cs delete UUIDoflogicalvolume family.
Letr me know once you did that.
There is a correction.
It will show some list of drives. Copy the UUID of Logical Volume Group.
diskutil cs delete typeUUIDoflogicalvolume group here
Let me know once you did that.
I thought you didn't know the password. That was the Master password ***** was talking about. It is the password ***** use to decrypt the volume and unlock the hard disk.
If you didn't run the commands yet, then do this. In the OS X Utilities screen, click Disk Utility. In Disk Utility, select the Macintosh HD on the left. Click on File menu and do you see Unlock or Decrypt ?
Master password ***** ***** password ***** File Vault and it is different from Admin password.
You use Master password ***** unlock or decrypt the hard disk. Admin password ***** ***** to install apps, updates etc
In the OS X Utilities screen, click Disk Utility. In Disk Utility, select the Macintosh HD on the left. Click on File menu and do you see Unlock Macintosh HD ?
After unlocking it, you have to turn off encryption. Turn off Encryption from the same File menu. After that we can reset the password.
You can now reset the password ***** Terminal. Close Disk Utility. Click on Utilities menu and top bar and select Terminal. Type resetpassword and press return. This will bring Reset Password ***** Isn't it ?
Select Macintosh HD and do you see the user account under the drop down menu now ?
It seems like you have two accounts. Reset the password ***** both.
Reset the password ***** both and you can get rid of one later. After resetting the password, you can even change the name to yours from System Preferences > Users & Groups.
If your dad's login is an Admin account, then you don't need the other admin account. If your dad's account is not an admin account but a standard account, then login to that admin account and change the dad's account to admin from System Preferences > Users & Groups (after logging into the account). Or you can create a brand new admin account for yourself from System Preferences > Users & Groups (after logging into the account).
When you login to account after resetting the password, you will get a Keychain error. So click Create New Keychain button and then follow the steps below to fix keychain.
Now just restart your Mac from Apple menu.
Is your dad's account listed there as Admin ?
Great ! Did you reset keychain ?
If you want, you can create a new admin account from System Preferences > Users & Groups.
For your information, the root account is the most powerful and privileged account than admin that is capable of modifying even the system files.
Yes, that's cool. If you don't reset keychain, you will get that annoying message frequently until you reset it.
How is it going ?
