I just bought an open box Macbook Pro at best buy. It is a 2013 model and was listed as excellent condition. The computer is excellent, but the charger is simply not right. The charger looks well used and has a date of 2009 on it. It also looks like it has a silver adapter plugged into the white part that would normally plug directly into the computer. I haven't even plugged the charger in yet, but is it normal for Best Buy to put an old charger in with a new open box computer? When I called Best Buy the person on the phone asked me if the charger worked. I thought they would just replace it because it is the wrong charger. I don't plan on returning the computer for this since I got a good price and love it, but I fear I have an old charger that probably has a limited amount of life left if it even works when I plug it in. What do you think I should do? If I just bring the charger into the store and try to exchange it wont they just think that I switched it out with an old one? I have never even had a mac before so I would not have had an old one to switch it with anyway.
