Reviewer: Blondevalgal

Rating: 5/5 Awesome computer at a great price. October 11, 2021 Needing to replace my old PC that I use for design, I purchased a 2019 iMac 27 with an 8TB hard drive. It was advertised as excellent condition (which meant small scratches on the housing). I tried but couldn’t really find any scratches. The Mac arrived quickly and the packaging was great - very well protected. The OS needed to be updated and it wasn’t difficult to migrate my software and files from PC to Mac. I purchased Parallels to run my Windows based software and, though I had been worried, it really is the simplest thing to do ever. And the screen on the 27! A designers dream! This purchase saved me thousands of dollars and I have a work station that will last me many years. I couldn’t be more satisfied.

Used, Excellent condition; 90 Day OWC Fulfilled Limited Warranty. (UACM1HS6XX21XXB) Qty: 1 Price: $1,869.00 I’m really happy with my new iMac. It’s great! It’s fast and reliable. I had a problem with Paragon’s extFS software. At one point Paragon, asked me to allow the Paragon’s extensions. I checked the box and then the iMac did a restart but never completed the reboot. Fortunately my Mac repair guy (Steve Mash) told me to do a net install. I did and everything was fixed. Eventually I installed the new version for extFS and it worked. I’ve had it two weeks, and there are no problems.

Reviewer: SuccessfulCobra-24019

Rating: 5/5 Incredible Screen July 31, 2021 I bought this to replace my 2012 Mac Pro, which was reaching the end of its upgradability and conveniently died. I had some experience using one of these, so getting my own to replace the MacPro was a natural move. Now that I have it set up, I am very happy. I was used to two displays, so I am using Mission Control to put different apps on separate screens as I do on my MacBook Pro. The Mac Pro had cards for extra USB outlets, so I had to add a hub to connect everything, and in place of the four internal drives I had, I have three externals connected, one as a backup of the 1 TB main drive, and two 3 TB drives for archived items and a backup. Functionally I can work pretty much as before. The 5K Retina screen is incredible and gives new life to my photographs. It is such a pleasure to work with. I'm glad I got the 2019 model, which still had 4 USB ports, so I didn't have to buy a bunch of adapters for my old USB devices. In terms of appearance, although this is a used machine, it looks brand new. I am more than satisfied.
