iMac (Retina 5K, 27-inch, 2019) repair questions answered

The iMac (Retina 5K, 27-inch, 2019) dates to 2019 as model A2115 and Apple publishes an official service manual for it, which is the document referenced on this page. We list 86 service parts for this model, and every part we fit is a genuine Apple part. Our work is covered for one year on brand new parts and 180 days on pre-owned parts and board-level repairs. We are in Tampa, walk-ins are welcome with no appointment, and you can also book a mail-in repair from anywhere in the country.

What are the model numbers for the iMac (Retina 5K, 27-inch, 2019)?

The iMac (Retina 5K, 27-inch, 2019) dates to 2019 and carries model number A2115, with the internal identifier iMac19,1. You can confirm yours from the Apple menu, About This Mac, or by reading the tiny model number printed on the base. Quoting that number when ordering parts is the only reliable way to avoid a part that looks right but does not fit, since Apple ships several variants that look identical.

Can the storage or memory in a iMac (Retina 5K, 27-inch, 2019) be upgraded?

The iMac (Retina 5K, 27-inch, 2019) 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, 2019)?

The jobs we see most on the iMac (Retina 5K, 27-inch, 2019) are ram upgrade, hard drive/ssd replacement, display replacement, power supply 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, 2019) 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, 2019) 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.
