Rating: 5/5 Excellent iMac February 4, 2018 This iMac was a snap to set up and came pre-loaded with Sierra (10.12) which was my preference as High Sierra does not support all of my applications. I migrated a 2008 MacBook to this iMac and use the desktop for all my computing needs as well as my Living Room entertainment device. Responsive, fast and in very good condition, I have absolutely no complaints.

I would recommend this item to a friend! This review is from Apple 20" iMac (2009) 2.66GHz Core 2 Duo - Used, Very Good condition.

Rating: 5/5 Best customer and technical support June 10, 2017 Reasons why MAC SALES IS EXCELLENT:

1. They care 2. They are very smart. 3. They process orders timely. 4. Their products are very good. 5. They offer live customer support. My reason for contacting them was to buy an older IMac so that I could edit videos with an older iMovie and with an older camera. I was told by technical support to contact the Manufacturer of the camera to find out the correct connections. The camera company told me not to use an adapter or my camera could be destroyed. Thank God for MacSales. I contacted MacSales and the technician helped me find the correct connecting cable. Within two days the IMac was delivered with the correct firewire cables, a back up wired mouse and a bluetooth adapter so I could use my wireless mouse. The computer and everything I ordered work flawlessly.

Rating: 5/5 Great media server December 13, 2016 I was looking for a cheap Mac to use as a media server. I also wanted it to run Lion, as I have an old program that won't run on something newer. This iMac came with a 2 TB drive, plenty for my media and a lot of growth. It looks brand new. Packaging was very good, a custom iMac box. For the price, this was a great deal.

Rating: 5/5 Excellent refurb iMac. Very pleased. August 23, 2016 I have been an OWC customer for 10+ years, I keep returning because of the excellent customer service and a high trust factor. Today I received my mid 2009 iMac, and am thrilled. 2.26Ghz, 8GB, 2.0TB HD, this was listed as "very good" condition. Not a scratch, dent, or blemish on it. Screen is perfect as far as I can tell after a full night of testing. Packaging was more than adequate, and not even a finger print on the plastic enclosed screen. Ordered on Saturday night, received Tuesday with free shipping. Best $389 I've spent, waiting on software upgrade from Apple so I can get this beast up to El Capitan. Will highly recommend OWC, and will purchase from them again. I am a long time Mac user going back to the SE days.
