We list 117 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 (24-inch, M1, 2021)?
The iMac (24-inch, M1, 2021) dates to 2021 and carries model numbers A2438, A2439, with the internal identifier iMac21,1, iMac21,2. 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 (24-inch, M1, 2021) be upgraded?
The iMac (24-inch, M1, 2021) is an Apple silicon Mac, so its storage is soldered to the logic board and encrypted to the Secure Enclave. Neither the memory nor the storage can be upgraded after purchase, and a logic board failure puts your files at risk, which is why we attempt a component-level board repair before ever replacing a board when the data matters.
What are the most common repairs on the iMac (24-inch, M1, 2021)?
The jobs we see most on the iMac (24-inch, M1, 2021) are display replacement, logic board replacement, power adapter replacement, speaker replacement. Apple rates this model's service difficulty as expert, 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 (24-inch, M1, 2021) 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 (24-inch, M1, 2021) 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.
