Rating: 5/5 Very Good Value September 20, 2016 I purchased this iMac for my grown daughter to replace an old PPC iMac. It's much faster and has a larger, better display than the old computer. Although this machine is several years old, it has lots of useful life for most computing applications and will serve her well. I used an extra keyboard and mouse to complete her system. It looks brand new and runs smoothly and quietly. The 2TB drive is much larger and faster than her old machine. OWC shipped the iMac quickly in a well-protected carton. I'll be upgrading the OS soon to a more recent version. OWC has been my number one source for all my Mac upgrades (four computers, three active). Good products, service and support!

Rating: 5/5 My Precious! October 6, 2015 My friends at Other World Computing had me hooked on the iMac 12,2 because it was a perfect upgrade from my MacBook Pro 3,1. The guys and gals at OWC provided superb details when I replaced the hard drive in the MBP and I had no hesitation with the purchase of the iMac 12,2.

Yes, I need the DVD/CD burner and the SD/SDXC card slot at the side keeps me happy. But, I’m getting ahead of myself. The night I ordered the iMac was past the same day delivery time period and when tomorrow came I had the email saying my order had shipped. Good — that it had shipped — cause I could have questioned my hard drive (add an SSD drive) and memory choice (longing to max it out). FedEx handled the industrial grade box with care and delivered in the morning of the anticipated day, yet my setup had to wait for more pressing home demands.

Once I had the time, out of the box and onto my desk. The ample wrapping around the unit had me guessing where to start, while a few careful cuts later exposed a most remarkable computer. I had only one extra purchase required and that was a DVI to Mini DisplayPort adapter to connect my 20-inch Cinema Display (worked perfectly).

With power and network connected I found the start button and powered up. It may seem minor, yet I had to put the dock and desktop to my favorites, and then, from the Apple App Store brought in Yosemite. Looking back I should have prepared myself for the direct Migration from the MacBook Pro to the iMac, but hey, all roads lead somewhere, even if they take you in a roundabout.

Oh, the El Capitan OS X 10.11 update went in with ease and with all this real estate from the 27 inch screen, I’ll be using Mission Control and relegating my Cinema Display to my MBP.

Okay, you ask, “Any problems with the iMac?” No, none whatsoever! I think OWC was being very conservative with a, “Very Good” label. I rate this iMac 12,2 as EXCELLENT!

I would recommend this item to a friend!
