What are the model numbers for the iMac (Retina 5K, 27-inch, Late 2015)?

The iMac (Retina 5K, 27-inch, Late 2015) dates to 2015 and carries model number A1419, with the internal identifier iMac17,1. 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, Late 2015) be upgraded?

The iMac (Retina 5K, 27-inch, Late 2015) is an Intel Mac from before Apple soldered everything down, so on many configurations the storage and sometimes the memory can be upgraded, and an SSD upgrade is often the single most transformative repair on a machine of this age.

What are the most common repairs on the iMac (Retina 5K, 27-inch, Late 2015)?

The jobs we see most on the iMac (Retina 5K, 27-inch, Late 2015) 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, Late 2015) 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, Late 2015) 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.
