We repair and upgrade the iMac 21.5-inch (2012-2017) at our workshop in Bermondsey, from power and start-up faults to storage upgrades and data recovery. The iMac 21.5-inch is a 2017 all-in-one Mac with a 21.5-inch screen, identified by model number A1418. Parts are matched to the exact chassis, so the model number matters when we quote.

What we repair on the iMac 21.5-inch
Screen replacement
The 21.5-inch panel is the front of the whole machine. We replace cracked, dark or lined panels and check the backlight circuit, because a black screen on an all-in-one is not always the panel.
Price confirmed before work starts
SSD and storage upgrade
We replace the hard drive or Fusion Drive in the iMac 21.5-inch with an SSD. The display has to come off to do it, and it is refitted with new adhesive.

Memory upgrade
Most configurations of the iMac 21.5-inch have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
macOS reinstall and repair
We reinstall macOS and migrate your data. Apple no longer offers the latest macOS for this Mac, so we install the newest version it supports.
We also carry out logic board repair, overheating and fan repair, macOS reinstallation on the iMac 21.5-inch, along with stand repair, no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
What we see on the bench
- From late 2012 the display is fixed with adhesive strips, so every internal repair starts with cutting the screen free and ends with new adhesive.
- Hard drives and Fusion Drives in these machines are now at the age where failures are common. Replacing them with an SSD is the most worthwhile upgrade.
- The 27-inch models have a memory door on the back; on 21.5-inch models reaching the memory means removing the display.
Data recovery from the iMac 21.5-inch
Many of these iMacs use a Fusion Drive, which spreads files across a small SSD and a hard drive. Both parts are needed for recovery, so please do not erase or replace either before we have looked at it.

Where the iMac 21.5-inch sits in the range
Its nearest relatives in the iMac (Intel) range are the newer iMac 21.5-inch 4K (2019). It is the earliest 21.5-inch model of the range that we list.
Questions
Can the SSD or memory in the iMac 21.5-inch be upgraded?
The drive can be replaced with an SSD, which involves removing the display. Memory is in slots on most configurations and can be increased.
My iMac 21.5-inch will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
How much does a iMac 21.5-inch screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
Is a 2017 iMac 21.5-inch still worth repairing?
It depends on the fault. A battery, SSD or charging socket is usually worth doing. A major board repair on an older machine may cost more than the machine is worth, and if that is the case we will say so.
