Hey Guys,
Going through setup assistant on a brand new machine w/ 10.12.5 using Full name : Administrator Account Name : admin which it would say that admin is a 'Name is used by another user".
I checked in the /Users directory and do not see the 'admin' account there. The management account is located in /private/var . There previously there was no issue prior to that, and we have not made any changes to the Prestage/DEP policies.
So , I thought that this is interesting. I used one of our created netrestore image of macOS 10.12.3 , ran through setup assistant and when doing the Administrator/admin account it did not complain.
I found this article which did help : https://discussions.apple.com/thread/2547071?tstart=0
I did a 'dscl . list /Users' in terminal and did locate the 'admin' account (made a completely different account)
then I did a 'sudo dscl . delete /Users/admin'
re-created Administrator/admin and it did not complain. I'm wondering if there is a fix around this? The administrator/admin account was never created to begin with!
