I am severely disappointed and upset, I spent my graduation money on this macbook to have for college. I trusted this company to give me a laptop that was atleast functional. For the first part it was, just a little slow. After a few times of me using it, The macbook would over heat, and not cool off properly. When I looked into the edges, I could see the inside WAS NOT cleaned properly, and I was correct when I happened to open the back of it up. It became very slow, and to the point of nothing working and I couldn’t even do a software update to fix the slow issue.I purchased this on September 11, 2023. I am not in college yet, so I have not used it much. Probably barely even 10 times. I had the macbook in a bookbag with a box of crayola markers everytime I was not using it, and when I was using it, I NEVER set anything on the macbook, and dropped it. I have no idea how the lines ended up on my screen. I went to use the macbook after a charged it overnight, and leaving it on a table and I discovered the black lines. I was left clueless.I cleaned the inside of the macbook with q-tips, and both ends on all of them are completely black. I am SO disappointed. I advise anyone who buys this product, PLEASE check all of the functions of it as soon as you get it, and even open the inside of it if you can. I expected better from amazon.
