my mid-2012 MacBook pro will not update
i recently purchased this machine as a stand alone for my small business; great bargain i could refuse plus LOVE apple products. now, when i go to update certain applications, i'can't. the previous owner's name/id pops up and i'm stuck. i'm friends with this individual and both of us together tried and tried to get her off, but no go.
help !!!
thank you in advance for your thoughts and time!
best regards,
chris
