What are the model numbers for the iMac (Retina 5K, 27-inch, 2020)?

You can confirm yours from the Apple menu, About This Mac, or by reading the tiny model number printed on the base.

Can the storage or memory in a iMac (Retina 5K, 27-inch, 2020) be upgraded?

The iMac (Retina 5K, 27-inch, 2020) carries a T2 security chip, which encrypts the soldered storage to the machine. That means a board swap erases your files permanently, so we recover data or repair the board itself rather than replacing it whenever the files matter.

What are the most common repairs on the iMac (Retina 5K, 27-inch, 2020)?

The jobs we see most on the iMac (Retina 5K, 27-inch, 2020) are ram upgrade, display replacement, power supply replacement, fan replacement. Apple rates this model's service difficulty as advanced, and we diagnose every machine on a bench supply and under a microscope before quoting, so you get a fixed price for the actual fault rather than a guess. Diagnosis is free.

Do you use genuine parts and what warranty comes with a iMac (Retina 5K, 27-inch, 2020) repair?

Every part we fit is a genuine Apple part, which keeps features like True Tone and the factory calibration working correctly. Brand new parts carry a one-year warranty, and pre-owned parts and board-level repairs carry 180 days. We are in Tampa, walk-ins are welcome with no appointment, and we repair machines mailed in from anywhere in the country.

If your iMac (Retina 5K, 27-inch, 2020) will not power on or was hit by liquid, it needs a board-level diagnosis rather than a parts swap. Call us on (813) 444-5595 and we will tell you what we are seeing before any work starts.
