Rating: 5/5 27" going out with a bang April 7, 2022 This iMac replaces a 2015 27" 4.0 Quad Core iMac. As this new one is the last iteration of the 27", I'm pleased to have gotten a good deal on it as it will be my last one. I've always loved my 2015, but this upgrade was definitely worth it. I'm very happy with my purchase from OWC.

Reviewer: steve-15523

Rating: 4/5 iMac update purchase February 23, 2022 This iMac arrived in perfect condition. Memory (32 GB) and SSD (500 GB) were installed as ordered. I had it delivered to the local UPS Store to avoid the "porch pirates" that have recently been plaguing my city. It came with Big Sur so I wiped the SSD and installed a clean Monterey OS. Then used Migration Assistant to move the data off the drive in my old iMac (27-inch late 2013) to my new (27-inch 2020 - current model). I've been using it now for several weeks and so far it has performed as expected. I'm satisfied with the purchase. My only suggestion would be to have included some advice for setting the machine up. I had to call my son for some help in the setup.

Response from OWC, Support February 24, 2022 Glad to hear this machine worked out so nicely for you.
