I currently own a MacBook Pro 13" which me and my wife have individual login ID's. I just got a new i5 Mac Mini and I was going to use Air Drop to transfer a file. I have not setup my wife with a login ID on the Mac Mini, yet when I turn on Air Drop it identifies the Mac Mini as hers. When I try to transfer the file to the Mac Mini from the MacBook Pro it tells me that the Apple ID certificate for my wife's name is invalid. The transfer has been canceled. I am don't know how to resolve this. I've never logged on as my wife on the Mac Mini and I am the only one with a login id on the Mac Mini. I cannot figure out why it shows her name. Any help would be greatly appreciated.😕
