I was able to start up the Mac as usual and add my apple ID. After initial boot-up I thought it was great: ran smooth, graphics looked good and there was very minimal cosmetic scratches.After about 2 days the computer would shut off after about 90 seconds of use, causing me to lose any projects I was working on. I tried to reinstall the OS and it kept glitching out. Computer wouldn't stay on for more than 30 seconds at a time. It wouldn't stay on long enough for me to remove my Apple ID. I had to go into recovery mode to remove the start-up disk and all my info. Still waiting on my refund...
