Update failed because of refund or buyer problem?
I am trying to update, something I have put off for a few weeks, and I am prompted that I cannot update using my ID. The only thing I can think of is that the macbook I am using was purchased refurbished, other than that I haven't bought or purchased anything. What's this about and how to I fix it? The only updates still queued are for iPhoto and El Capitan. Thanks!
MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.5)
