Hi,
Sorry about the late reply!
First I used Migrate Assistance to transfer data from my Dad's Desktop to mu new iMac. It copied everything, but it also made my Dad's account the main one, call Jim. After this I create account (admin) my myself called john. I made sure I was logged out of both accounts.
I would then logged in as myself, went to Users & Groups to try and log out the use Jim but when I clicked on the account it did nothing, there was no response something like when an item that is greyed out. I at no problem clicking on the Guest account and make modifications if I wanted. Yes I did unlock the system with the admin password so I cold make changes.
I felt the best way, since everything I tried had failed I did a clean install. now I have everything set up the way that I want.
Yes the error was that I was unable to to select the other admin account.
Thanks so much for your help!
Johnny
