Rating: 5/5 Great for Home DAW rig September 13, 2018 I am a professional sound engineer, audio producer and music composer. I needed a second Pro Tools rig to use in my home office for editing, composing and dealing with occasional client emergencies, when I can't get to my main studio location. For years I ran a small Pro Tools/MBox pro system off my Macbook Pro, but the laptop did not really have quite enough processing speed or memory to be effective. So I took a look at larger form computers with more processing power and ended up with an OWC reconditioned 2011 iMac. In addition to an internal 1TB HD, I had a 1 TB SSD added. It had a superdrive and a Firewire 800 port, both features I needed. It also looks very sleek and elegant in my editing room, with a large and very useful display. The iMac offers a very good bang for the buck ratio, especially reconditioned. My home editing system now purrs along contentedly with way more system resources available than previously. It is an absolute pleasure to work on my "little" system now!

Rating: 5/5 Very Nice January 8, 2018 First time experience buying a used Mac from MacSales.com. I received it next day as promised in great condition, opening the packaging I was impressed with the product packaging itself and the overall condition of my IMac exceeded it's described condition. Once placed the IMac fired right up and so far running like a champ.

Great Job MacSales!!!

Reviewer: NobodySpecial Location: NobodySpecial Experience Level: Power User Owned Product: 1-3 months
Rating: 5/5 Great value for the buck November 2, 2017 This 27" iMac was advertised as in good condition. I didn't find a scratch on the computer and would say the external condition was excellent.

I ordered a basic 8GB with 1TB HD machine with no keyboard or mouse. I added a 1TB SSD and four 4GB SIMMs. The whole upgrade took about an hour and then I ran a memory test for 24 hours.

With no OS on the SSD, I did an internet recover and installed High Sierra. BIG MISTAKE! Apple says a mid 2011 (12,2) will run High Sierra, my USB keyboard stopped working. After a day of trying to get it working, with no luck, I gave up. I installed Sierra and everything works perfectly!

The Apple developer and user forums have all kinds of issues with High Sierra and USB keyboards.

So, for half the cash of a new iMac, I have machine with an i5 quad core processor, 32GB RAM and 1TB SSD. All Software that was running on my 2009 iMac running El Capitan now runs faster on the new machine under Sierra. MS Office 2008 also runs!

Rating: 5/5 Very Happy April 18, 2017 I am pleased with my 27" iMac. The screen is great, it is working like a charm, and is pretty much just what I wanted. It worked beautifully out of the box. However, I had trouble with the Time Machine backup from my old machine, and it locked everything up. Tech support was awesome. The tech who helped me knew his stuff, and we had the problem solved quickly. I have been getting memory from OWC since my Apple SE 30, approximately a million years ago. I have always been pleased with their product, prices, and service.

Rating: 5/5 The 27" iMac arrived on time and works as expected. September 6, 2016 MacSales team members did well. Delivered as promised.Set up and working in less then 15 minutes. Kicking myself for not ordering the touchpad and wireless keyboard at the same time. This is for my office. When I retire and move will plan on purchasing again from MacSales.
