Rating: 5/5 Excellent second-hand iMac October 31, 2021 Replaced my 12,2 iMac which could no longer cope. Very pleased with this purchase, despite some unnecessary complicated customs delay (shipping outside U.S.). Some minor cosmetic wear & tear on the machine. OWC upgrade to 2 TB SSD (although I did not know it would be a PCI-Ex disk......which however means I can use one of my "old" SSDs and add even more storage). Upgraded OS to 11.6, performance is still excellent, perfectly sufficient for a few years to come (or at least until Apple drops Intel support completely)

Rating: 1/5 Never again August 18, 2021 We have been customers for many years and have also always been satisfied. But what we have now experienced is beyond imagination: We ordered an iMac for our office in Amman (Jordan), which then also arrived after three weeks. What nobody told us: The iMac has no keyboard and no mouse! An iMac without a keyboard and mouse is like a car without wheels. If you sell an iMac, you should sell it completely. According to Apple, an iMac is only "complete" with keyboard and mouse. This is a total customer screw-up - we also made a phone call. The audacity and impudence of the "customer service" cannot be described. He referred to the product description of the offer. After consulting with Apple, we will now have this matter clarified in court and have first reduced the invoice.

Response from OWC, Support August 18, 2021 Hello legal-28359. I'm sorry to hear that you were disappointed in your iMac purchase. Each Used Mac on our website declares what is included, and for Mac Pros, iMacs, and Mac minis it is stated that the unit is being sold without keyboard or mouse; these must be purchased separately.

Rating: 5/5 My used 27” iMac from OWC looks like new! June 24, 2021 My new to me 27” iMac was customized to perfectly meet my needs (32 GB memory, 2TB SSD hard drive). The way it was packaged for shipping was amazing! Minimal but extremely sturdy support that kept that big monitor from torquing in transit. I’m loving my iMac!

Rating: 5/5 Great Experience! June 5, 2020 I ordered a refurbished 27' 5k iMac a few months ago from OWC/MacSales. It has been working great! The price was probably half of what I would have paid had I purchased new, plus I was able to max out the RAM and SSD storage to get exactly what I wanted. Because computer performance and software has largely stabilized, it is no longer necessary to have the newest computer on the market to have great performance. In fact, I get better performance from my OWC refurb iMac (because I was able to max out the specs), than I would have if I had compromised and ordered the latest from Apple with fewer options. Thanks OWC!

Rating: 5/5 Would and will order again from OWC. March 23, 2020 New iMacs and the Catalina OS were not appealing to me because I enjoy and find important a couple of 32 bit software programs.With delayed deliveries of parts and completed machines occurring early in the pandemic, I decided to look at an OWC spec'ed iMac and the 2017 with some desirable added memory and storage was just the ticket. Ordering online was simplicity itself and the machine arrived safely and has performed flawlessly. The Parallels bundle was a good deal, too, so the iMac runs a speedy WIn10, too.

Rating: 5/5 Great Replacement for an Old iMac January 24, 2020 Last week, the motherboard on my 11,3 2010 iMac went South. I didn't realize how reliant I am on my Mac, so based on previous positive experiences with OWC, I visited their website to search for a refurbished iMac. I liked the fact that I was able to customize my new machine, and purchased this model with 32 GB RAM and a 1 TB SSD. My new iMac is much faster than the one it replaced, and I absolutely love the Retina display. My sales experience was flawless; the guy who assisted me was knowledgeable and friendly. The entire interaction/transaction was great, and I received my new iMac in two days via ground shipping. Happy to have saved a bit of money while concurrently being able to configure my iMac to meet my needs.

Rating: 5/5 Silent Power from Beyond December 29, 2019 This was basically a brand-new, custom-built iMac at a massive discount. The machine is silent, powerful enough (3.8 mHz) to run X-Plane effortlessly. With 32 GB RAM and a Fusion Drive, it's like everything is in RAM already. Click an app and it's on the screen instantly. Tap the space bar and it wakes up instantly. The rechargeable keyboard & mouse are so nice. One charge lasts weeks. No more buying batteries! (Note: The reason the mouse can't be used while charging is that if it was plugged in while in use, the electric cord would get bent back and forth so much it would break.) We love this machine. ??
