如果您刚刚拥有一台 Mac^(Mac)或者您已经使用了一段时间，那么您很可能使用管理员帐户。在大多数情况下，您是唯一使用Mac的人，因此您无需创建另一个用户帐户。 

但是，如果您与其他用户共享您的Mac，您可能希望摆脱这些额外帐户的原因有很多。 

例如，您可以删除Mac上的用户以： 

• 释放宝贵的磁盘空间^{(Free up valuable disk space)}
• 拒绝其他用户访问您的 Mac
• 在您想要处置或出售 Mac 时做好准备^{(Prepare your Mac when you want to dispose of or sell it)}
• 解决常见问题

无论您是想整理计算机，还是与他人共享计算机并拒绝他们进一步访问，我们都会向您展示如何在Mac上快速轻松地删除用户。 

如何在 Mac 上删除用户^{(How to Delete a User on Mac)}

如果您是第一次设置Mac，设置助手会自动创建一个管理员帐户。 

此帐户具有允许其修改操作系统的权限，包括安装应用程序、添加不同类型的用户帐户以及访问其他帐户类型无法 访问的Mac的关键区域。^(Mac)

其他类型的帐户包括： 

• 标准帐户：当您的^{(Standard account)}Mac运行不稳定、出现死亡风车或Safari崩溃或停止时，非常适合用于故障排除。
• 来宾帐户^{(Guest account)}：无需密码即可临时访问其他用户。用户注销后，其主文件夹中的所有信息都会从您的Mac中永久删除。 

虽然您可以删除Mac上的标准用户帐户和来宾用户帐户，但如果无法访问辅助管理员帐户，则无法删除管理员帐户。

但在您删除Mac上的用户帐户之前，请务必将存储在该帐户下的所有重要文档保存到云^{(the cloud)}或外部 USB 闪存驱动器^{(external USB flash drive)}。

1. 接下来，在密码^(Password)和验证^(Verify)字段中输入用户密码，然后添加提示^(Hint)以帮助您稍后记住密码。 

1. 选择创建用户^{(Create User)}>使用现有文件夹^{(Use Existing Folder)}。 

注意^(Note)：如果您在删除过程中选择了删除^(Delete)主文件夹选项，您将无法使用上述步骤恢复用户帐户。这是因为它会删除用户的主文件夹、文档以及他们的所有信息。但是，您可以使用Time Backup机器来恢复帐户。

删除那些额外的 Mac 帐户 ^{(Delete Those Extra Mac Accounts )}

How to Delete a User on Mac

If yoυ just got a Mac or you’ve been using it for some time, уou most likely use the administrator account. In most cases, you’re the only оne who uses your Maс, so you won’t need to create another user accоunt. 

However, if you share your Mac with other users, there are several reasons why you may want to get rid of those extra accounts. 

For instance, you can delete a user on your Mac to: 

• Free up valuable disk space
• Deny other users access to your Mac
• Prepare your Mac when you want to dispose of or sell it
• Troubleshoot common problems

Whether you want to tidy up your computer, or you’ve been sharing it with someone and want to deny them further access, we’ll show you how to delete a user on Mac quickly and easily. 

How to Delete a User on Mac

If you’re setting up your Mac for the first time, the setup assistant will automatically create an administrator account. 

This account comes with privileges that allow it to modify the operating system, including installing apps, adding different types of user accounts, and accessing critical areas of your Mac that other account types can’t. 

Other types of accounts include: 

• Standard account: Ideal for troubleshooting purposes when your Mac is acting flaky, exhibits the pinwheel of death, or when Safari is crashing or stalling.
• Guest account: Gives temporary access to other users without a password. Once users log out, all the information in their home folder is permanently removed from your Mac. 

While you can delete both the standard and guest user accounts on your Mac, you can’t delete an administrator account without access to a secondary admin account.

But before you delete a user account on your Mac, be sure to save any important documents stored under that account to the cloud or an external USB flash drive. 

Delete a Standard or Guest User on Mac

If you’re an admin, you can delete other users on your Mac, along with user groups that you don’t want.

1. Select Apple menu > System Preferences. 

1. Next, select Users & Groups. 

1. Select the padlock icon at the bottom left of the Users & Groups screen and enter your admin password to unlock the preference pane. 

1. Next, select the user or group you want to delete, and then select Remove (minus sign) under Login Options.

Note: You can’t select users who are currently logged in to your Mac.

1. Select one of the following options: 

• Save the home folder in a disk image: This archives the user’s information and documents in /Users/Deleted Users/ so the user can be restored later if necessary.
• Don’t change the home folder: Leaves the user’s home folder as is without removing their documents and information. 
• Delete the home folder: Removes the user’s home folder from the Mac along with all the user information and frees up storage space. 

Note: For a sharing-only user, there’s no home folder associated with that user.

1. Select Delete User.

1. Repeat these steps for Guest user accounts or just disable the Guest user option by deselecting the Allow guests to log in to this computer checkbox. You can always enable the Guest account later by selecting the box again when you’re ready to share access to your Mac with others. 

1. Select the padlock icon again to lock it and close the Users & Groups window.

Restore a Deleted User on a Mac

If you accidentally deleted a user on your Mac, you can reinstate them. However, that will depend on how they were removed. 

For instance, if you choose the Save the home folder as a disk image or Don’t change the home folder option, you can restore the deleted user. Otherwise, their documents and information are removed during deletion. 

Restore a User Whose Home Folder Was Saved as a Disk Image

You can restore a deleted user if you saved their home folder as a disk image during deletion. 

1. Select Go > Go to Folder.

1. Enter /Users/Deleted Users.

1. Select Go. 

1. Open the disk image (DMG) file for the deleted user’s home folder. The file starts with their name, for example, alexia.dmg. The folder’s contents will appear in a new window.

1. Select File > New Finder Window.

1. Double-click the Users folder at the bottom of the new Finder window to open it.

1. Press and hold down the Option key on your keyboard while dragging the DMG file icon for the deleted user into the Users folder. 

1. Enter your password to continue. The home folder is now copied to the Users folder.

1. Select Apple Menu > System Preferences > Users & Groups. 

1. Next, select the padlock icon and enter your password to unlock the preference pane. 

1. Select the Add (+) icon under Login Options at the bottom left of the Users & Groups screen. 

1. Next, select New Account and then select the type of user. 

1. Enter the user’s full name – the same name as the home folder you restored. 

1. Enter a password in both the Password and Verify fields and add a Hint to help you remember the password later.

1. Select Create User and then select Use Existing Folder.

Restore a Deleted User from the Home Folder

If you saved the deleted user’s home folder, you can restore their profile on your Mac using these steps. 

1. Select Go > Go to Folder. 

1. Enter /Users/Deleted Users and select Go.

1. Find the deleted user’s home folder and double-click the disk image of the deleted user account e.g., Alexia.dmg to open it.

1. Select Go > Go to Folder > /Users folder.

1. Press and hold down the Option key while dragging the deleted user’s disk image icon to the Users folder.

1. Enter your admin password to proceed. The deleted user’s home folder will be copied into the Users folder.

1. Select Apple menu > System Preferences > Users & Groups.

1. Next, select the padlock icon and enter your admin password to unlock the preference pane. 

1. Select Add (+) under Login Options. 

1. Next, select New Account and then select the user type. 

1. Enter the user’s full name, and use the same name in the Account name field as the home folder you restored. For instance, if the home folder name is Alexia, enter that name in the account name field. 

1. Next, enter a user password in the Password and Verify fields, and then add a Hint to help you remember the password later. 

1. Select Create User > Use Existing Folder. 

Note: If you selected the Delete the home folder option during deletion, you won’t be able to restore a user account using the steps above. That’s because it removes the user’s home folder, documents, and all their information. However, you can use the Time Backup machine to restore the account.

Delete Those Extra Mac Accounts 

You can have multiple user accounts on your Mac just as you would on Windows and Linux operating systems, where they can keep their settings and files separate. When you’re ready to delete those users on your Mac, just follow the steps listed above.

If you have a Windows PC, turn to our guides on how to delete a user profile in Windows 10 and how to fix a corrupt user profile in Windows 10 to help you manage user accounts.
