I got the Mac 15-inch model with 16 GB RAM and 512 GB. When I opened the computer, the screen was blinking. There was no physical damage to the computer, and the box was completely intact. I believe this computer was not going through any process to check the quality and the problem of the computer before it was resold to me. It was very disappointing. I returned the laptop, and I’m waiting for a refund. The refund was not what I was looking for because I called customer service, and I asked Amazon customer service for replacement, but they said I must get a refund and then buy again whatever I want. The whole thing will take time, and this is another disappointment.
