Hi, i just sold my macbook pro to buy rMacbook, or so i thought. We have a big site selling things here in Sweden, and i thought it would be ok. It was he pay the money on delivery, and have 24 hours to inspect. Well for him its perfecly safe, me not so much i supose. Now he emails me telling me letters swedish letter Ö and M not working and several other keys are glitching. Since i been using the computer till the day i reset and reinstall it for him to just enter icloud account. I wonder is there any way for me to prove thrue online history that the computer was used ? Safari or in onenote. Even when i sold the computer i wrote the add on the macbook. Can i call apple support perhaps, is there anyway to prove the computer was working the day i sent it ? I did make a small video, but ofcourse didnt think about hitting every damn key for proof. Thats probably 1000 dollar i lost on my late 2013 macbook, or worst have it sent back to me broken , got damn I had the email correspondance on the macbook, but i guess it doesnt show anywhere in the mail it was sent from this and that computer ?
