Bought this computer late oct 2021 and let me tell, it was expensive mistake! First off the product description page doesn't anything about what year the refurbished computer is from. In my case, it was a 2012, which means you can't upgrade the OS past Catalina and it's dog! It's obvious that it is the seller's intention to purposefully not divulge this important fact, which should be required in the description! Secondly, the photo shown is pure switch and bait since it shows the Imac with a wireless Apple keyboard. But with the computer you receive a cheap Chinese keyboard and mouse...And guess what that keyboard stopped working after 6 months. The seller has promised to send me a replacement since April. Still nothing. Terrible customer service response time.  But the most upsetting to me is that this computer has 16G of Ram but it is as slow as a snail. I don't even run demanding softwares but I constantly have to force quit app. So BUYER BEWARE...Highly UNRECOMMENDED!!!
