What Can Be Done If You Can’t Delete Admin User in High Sierra?

The use of Migration Assistant helps the members of the Apple family to move their personal documents, apps, and settings to a new MacBook or Mac in a safe and efficient manner. The utility has been designed to zap the need for the exhausting process of manually locating and copying all necessary files and folders to a new machine. By simply positioning the two computers next to each other and connecting them via Wi-Fi, it is possible to quickly initiate and conduct the information transfer. In addition to moving files, the following items can also be transferred to a new Mac: computer and network settings, applications, and user accounts.

To set up and run Migration Assistant, there is a need to have an administrator account. Prior to using this easy method of data migration, Mac owners are asked to enter their administrator password. However, after the data transfer is finished, some users discover that the new Mac has two administrator accounts one of which cannot be removed. The problem is especially prominent for macOS High Sierra users. The significance of the issue is underscored by the fact that the extra admin account opens an additional avenue of using the Mac with administrator privileges, which increases the security threat. The diminished security associated with the extra account means that if someone logs in to the computer as an administrator, they can tamper with essential OS files, steal data, and remove user accounts among others. Therefore, it is always necessary to ensure that a temporary administrator account is deleted after the process of migration is successfully completed.

This article aims to help those macOS High Sierra users who have migrated their data to a new machine to delete their old administrator account.
