Can't get back to original user
I am using macOS Tahoe 26.0.1. I recently bought a new MacBook Air M4, and I attempted to migrate from an old MacBook Pro (early 2013). My previous username was OldName, let's say. I had already created a new username on the MacBook Air called NewName. But I must have done something wrong when I migrated, because when it was finished, I had 3 user folders: Deleted Users (containing the folder NewName), OldName showing the Home icon, and containing the following folders: Public, Downloads, Movies, Music, and Pictures. There is no Desktop or Documents folders, both of which are in the Deleted Users/NewName folder.
Can someone tell me how to move the Desktop and Documents folders out of Deleted Users/NewName and into Users/OldName. Either that or change the name of the User folder to NewName. I don't know what happened, but I must have migrated the old user folder accidentally.
MacBook Air 15″, macOS 26.0
