Rating: 5/5 Smartest Computer Purchase Ever April 26, 2018 Aside from my order being handles most professionally, the iMac I purchased has been an outstanding champ! Due to my work as a pro audio sound post-production (designer) I had to downgrade to El Capitan myself for all my software to work exactly right. This was easy, as I;m a Geek.

It would be nice if OWC offered *base* installations of still actively supported versions of OSX. I have to avoid any updates that patch for the Spectre and Meltdown CPU flaws as there are indeed times, and I'm monitoring the system, when I need 100% from all cores.

Best computer purchase of my life. Hands down.

Rating: 5/5 This is a great product in view of its time in service ie.2011. April 24, 2018 When my 2006 iMac finally succumbed to old age about a month ago I looked at the advertisement I had received from Mac Sales for the 21.5 inch iMac. Pyment with my U.S.A. Visa was no problem and the computer arrived at my home in Canada 10 days later notwithstanding possible US/Canada border problems and taxes. The computer appeared to be in excellent condition, as advertised and has so far worked perfectly. I installed OS 10 El Capitan , which has some iirritating issues that are taking some getting used to. On the whole I am totally pleased with the iMac and the support I have received fromMacSales.

Rating: 5/5 Just as good as brand-new March 18, 2018 My parents who are both well into their 80's were so frustrated with Windows they stopped using their PC and were angry. My Brother and I give my parents a reconditioned iMAC for their anniversary and they totally love it. The unit functions and looks new, everyone loves it and they are now "playing" with what they can find on google searches, videos, music etc for a couple of hours a day. Great investment and I recommend these reconditioned iMACs.

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 Best replacement ever! December 15, 2017 I bought this for my mom after years of taking care of her Windows machine. I couldn't help her fix the problems she had like I did before. I switched to an Imac more than a decade ago so I wasn't keeping up on all the new threats or inherent problems of Windows or her machine. Best thing I ever did!! She took alil time to get used to different arrangements and names of things, she is in her mid 70s, but now is pretty good. I'm hardly called to help her because she can figure out stuff herself and her Imac just works! So much less stress for both of us.

Rating: 5/5 Great deal on a refurb iMac August 13, 2017 Our large (280+students) homeschool co-op needed a computer on premises so we did not have to rely on anyone bringing their laptops. We access our registration web site and co-op management FileMaker app remotely. My first through was Other World Computing. I have been a faithful customer for over a decade for all things Mac and this iMac was just want was promised. It was well packaged, arrived on time, booted up and ran well. I upgraded it to Sierra, installed the latest FileMaker Pro 16 and it's been running perfectly for weeks!

Rating: 5/5 Better than new... August 8, 2017 This lightly used and upgraded iMac meets my wife's needs to replace her 10 year old iMac. She likes the built-in DVD drive, the speed of the Neptune SSD and the 12 GB of fast memory. And unlike her old iMac that could no longer get upgrade Mac OS X, Sierra installed on this one very nicely. And now that all of our Macs are on the same version of OS X, tech support for me on our network is simplified.

Those who have to have the latest, greatest specs from Apple can pay the tab for the latest and greatest according to the reviewers, but sometimes a bargain upgrade from MacSales is just what is needed.
