Rating: 5/5 My new iMac January 15, 2018 What a thrill to unpack this new (to me) iMac, loaded with High Sierra and running like a champ. My original Mac was a iMac G4 Snowball which I bought from you in 2000 and which still has wonderful graphics but is getting creaky. Plus the OSX 10.4.11 just doesn't cut it any more. I am amazed by the resolution of the screen and the speed of operation. After ordering the bluetooth keyboard, during the wait I plugged in the original wired keyboard from the old iMac and it took off fine. The Rocket Weekly blog is making sense of all the new features of High Sierra. Thanks again for the work you do.

Rating: 5/5 Great iMac at a Great Price June 26, 2017 This iMac rocks. My old Mac mini started to have video card issues. In fact, the video does not work anymore. I needed a replacement Mac for my home use. Looking the iMac the price was less than what I purchased my original Mac Mini, It came with more memory and a fast processor. It's a beautiful iMac, fast, sleek, and perfect for the space provided. The screen is huge. I would recommend this iMac. MacSales is awesome. They work with you and have never steered me wrong. Five Stars!!!!

Rating: 5/5 Good deal. March 31, 2016 This was a good deal. It arrived on time, expertly packed. It is a beautiful machine and it runs perfectly. I called tech support with a question and got right through to a friendly and helpful person. I will be buying from MacSales again in the future and I strongly recommend them to anyone who needs to meet a computing need without going broke. An associate of mine told me about how reputable this company is and I really have seen proof now. I am very pleased with my purchase.
