At first, I was really excited to open this. It looked brand new, and even had the official Mac mouse and keyboard. Everything was sealed with plastic, which made me feel as if I was unpacking a new product, rather than something used and refurbished.BUT....Right away, the computer took 10+ minutes to load, and then froze. I had to unplug and plug it back in. For the next few days, it had a booting problem. Then, programs like Google Chrome would uninstall and then automatically want to reinstall every time I restarted the computer. During one startup, it even said "Mac OS not found", and I had to unplug again. The computer would get slow in general, even though it was supposed to have the best of the best hardware installed.Keep in mind, this was only after having it for about 2 days. So I barely touched it, and it was already having huge software issues from the get-go. I tried to Google the issues to see if there was anything I could do to fix it, and everything I found told me that these were serious hardware issues. So I was forced to return the computer and get my money back.Normally, I like being frugal and not buy anything brand new. I've bought used macs from eBay before without much of an issue. This was my first time buying Amazon Renewed, and I am never going to use this service again. Clearly, whoever they hired to make sure these computers work made a mistake with this one.
