no users available for authorization

I am trying to prepare my MacBook air for resell. I have been following the steps on line and am to the step of reinstalling and it says "No users available for authorization an error occurred while reading device owners. Ensure that some user is allowed to administer this computer." What do I do now?

authorising / deauthorising a computer does not work Hi, I bought a new Mac and wanted to authorise that new computer. It failed by saying that there were too many devices authorised. That was true. I logged into my account and removed three old devices from the authorised devices list, ending up in a list of three devices which still should be authorised. That's now two days ago. Any attempt to authorise the new computer ends up in an error message, that there would be already 5 computers authorised. Seems that I am in a deadlock. I hope anyone can help me with this.

My mac says there is an authorised computer to my account but doesn't allow me to de-authorise it So i have had this long-standing concern that there is unauthorised access to my MacBook. It looks like there is an admin account to which I am a subsidiary user. In most cases, i am unable to make changes to my account such as de-authorising a user from my iTunes account or even accessing normal information. I am able to click on important Mac hyperlinks on my system but it never allows access. Currently, i am trying to de -authorise my account, it initially said that there were 2 accounts authorised, i am able to de-authorise my immediate account but it does show that there is another one, which i am unable to access to de-authorise. can anyone explain how this is ?

Trying to reinstall macOS on BRAND NEW MacBook Air And it’s telling me there are no users available for authorization. I did a restore to its factory settings because some applications got transferred from my old Mac I did not want nor did I want any files to do with them. Thought the restore would be easiest. Clearly not. Why can’t I get past this screen?!?

Hi DClark118a,

If you erased your Mac using Disk Utility, you might have chosen accidentally to only erase one of the volumes, instead of choosing to erase the volume group.

To fix this issue, open Disk Utility in macOS Recovery. Delete the volume named "Macintosh HD - Data", or just "Data". Then, erase the volume named "Macintosh HD".
