Messed up our Apple ID
Hello there. We just got a new iMac at church. One of our guys was setting it up (he's not experienced with mac's). When it asked him to create an apple ID, he entered (i won't actually put it all in here for security purposes): abcdefg@gmail.com
So now, it thinks his apple ID is: abcdefg@gmail.com@icloud.com
I think we've messed something up. What do we do?
