Mac changed the username and lost the administrator privileges

It's so magical, it just succeeded (

It's been more than a year since my mac was downgraded to an ordinary user because of changing the administrator username.,At that time, all kinds of search methods on the Internet,Basically, I can't understand these **。 I also have the problem of paying attention to spaces, and I used to check every time I finished writing but it just failed.

Today, the big brother who installed the dual system for me looked at the web page I searched,Enter the three lines**,The first two enter big brothers didn't knock,Reboot restarted after entering。 Reboot is after booting and selecting"Normal user"and"Guest user"The interface,We didn't think much about it,Or log in to the ordinary user after being downgraded,And then it jumped out of the setting command box that is almost the same as the landlord's screenshot,Many steps"Continue"After that, you will arrive at the same interface as the landlord's screenshot。 After the end of the computer, it seems that the settings have been reset.,Open the preferences to check and find that the new account just set up is indeed an administrator.,It's too frightening.。

There are many steps after entering the command box, and the most important thing is to enter Apple (email, used to download software and shopping customers) after connecting to wifi, and then Apple's official website will automatically send a verification code to your bound mobile phone. After the verification is completed, you will start creating a new user, and it seems that you will have to create a different username and password. After that, you will be asked to enter the original administrator password.

Because my current ordinary administrator is the original administrator, I also entered this password, as if I entered it twice, and finally "deciphered" it. Then select some consent agreements and enter the reset Apple desktop, open the preference check users and groups, and find that the new administrator is successful.

I don't dare to move the administrator account anymore,,, and it is not convenient to reinstall the system, either go to the 4S store to spend money to reinstall or warranty during the warranty period, or reinstall the system disc according to the process of online shopping, but the premise is that the things in the computer have been backed up in the mobile hard disk, and the mobile hard disk is about 1t five hundred yuan.

The newly bought machine of the eldest brother is the easiest, and the system is reinstalled directly, which is very simple, and will not ask again. Once you've reinstalled the system, it's good to set it up again.

I would like to ask if this will lead to the loss of files.

While using a Mac computer, know that the administrator has greater privilegesIf you want to change an ordinary user to an administrator, here is how to share it.

1. First turn on your Mac computer and click on the Dock bar to open System Preferences.

2. After opening, click on the Users & Groups option inside.

3. To set it here, you need to unlock it first, and click on the unlocking icon in the lower left corner.

4. A window will pop up after clicking, enter the login password of the system here, and click the Unlock button.

5. Click on the left side of the list of blind users that need to be set, and then on the right side check the option of "Allow users to manage this computer" here.

6. After looking at this user, you can see that this user has become an administrator.

There are two main problems that arise.

1.Data recovery issues.

At this time, you can see the data of the user before the modification.

2.Administrator privileges issues.

While the data problem was restored, another, more serious problem arose. The new username account is just a normal user account, and there is no administrator privilege. I no longer recognize the previous username and password with administrator privileges when you enter the operation that requires administrator privileges.

wtf？Don't have admin privileges anymore? Isn't the computer going to be wasted?

nnd, changing the username will lose the administrator privileges, and you still allow me to change the username? This is a fatal bug! I don't know what the god-like Apple thinks.

Because there are very important things now, time does not allow delay, and some methods of searching on the Internet do not dare to use them now, I don't know if there will be any moths. After communicating with Apple's technical service to describe the situation, Apple's technical service provides the following methods to create a user with administrator rights.

After the reboot is completed, it is time to create a new user, and you can follow the prompts.

Follow the above steps to create a new user with administrator privileges. If you need the data of the previous user, you can log in to the user you need.

At that time, the operation was Apple's technical service to support me to complete the entire operation process, and I would like to thank the technical support staff for their patient guidance!

Sometimes, if we want the username of the administrator.

It should be noted that the administrator account at this time is a new account, after logging in, you will find that the original files are gone, do not panic at this time, if the original file is not particularly important, in the settings-> users will delete other users; If another user has important files, you can keep the user and select the user to log in when the computer is turned on. If you want to move important files to the administrator account, you can share them or copy them.
