Your iMac is the centre of your home office, your creative studio, or your family’s digital life. And when it stops working, everything grinds to a halt.

Or the machine simply will not power on at all. At Repair St Andrews, we have been repairing iMacs since 2011, handling everything from simple hard drive upgrades to complex logic board repairs. Bring your iMac to 1 City Rd and we will diagnose the problem and get it fixed.

Common iMac Issues We Fix

Display Problems

Vertical or horizontal lines, flickering, dark patches, or a completely black screen. iMac display issues can stem from the LCD panel itself, the display cable, the GPU, or the logic board. We diagnose which component has failed before recommending a repair.

Hard Drive and SSD Failure

Clicking sounds, the folder with a question mark on startup, or repeated kernel panics. We replace failed drives, recover data where possible, and can upgrade mechanical drives to solid-state for dramatically better performance.

Slow Performance and Spinning Wheel

Older iMacs with mechanical hard drives become painfully slow over time. The most effective fix is upgrading to an SSD, which can make a 2012 iMac feel like a new machine. We also diagnose RAM issues, failing drives, and macOS corruption.

Overheating and Fan Noise

iMacs that run hot and sound like a jet engine usually have dust-clogged fans, dried-out thermal paste, or a failing temperature sensor. We clean, re-paste, and replace sensors to restore quiet, cool operation.

No Power or Random Shutdowns

If your iMac will not turn on, shuts down randomly, or restarts in a loop, the fault could be the power supply, logic board, or a thermal sensor issue. We trace the electrical fault and repair at component level.

// OUR PROCESS

Our iMac Repair Process

We keep the process simple so your device is back in your hands quickly.

Full Diagnostic

iMac repairs start with a thorough diagnosis. We remove the display assembly to access the internal components and test the hard drive or SSD health, RAM integrity, power supply voltages, GPU function, and logic board status. We use diagnostic LEDs on the logic board and Apple's hardware diagnostics to pinpoint the fault precisely.

Repair or Upgrade

Based on the diagnosis, we carry out the repair. Whether that is replacing a failed hard drive, upgrading to an SSD, re-flowing or replacing GPU chips, swapping the power supply, or doing component-level logic board work. If your iMac would benefit from a performance upgrade alongside the repair (such as adding RAM or an SSD), we will suggest it.

Reassembly and Testing

iMacs use adhesive strips to seal the display, and getting the reassembly right matters for dust-free operation. We fit new adhesive, carefully reseat the display, and run extended stress tests to verify the repair is solid. Temperature monitoring, display checks, storage benchmarks, and a full macOS boot test.

Turnaround Time

iMac repairs typically take two to four working days, depending on the fault. Straightforward upgrades like SSD installation and RAM expansion can be completed within one to two days. Logic board repairs and display replacements may take three to four days, especially if parts need to be sourced. Because iMacs are desktop machines, we understand you cannot simply use another device in the meantime, so we prioritise getting them back to you quickly.

Pricing

iMac repair costs depend on the model year and the specific fault. An SSD upgrade for an older iMac is one of the most cost-effective repairs we offer, dramatically extending the useful life of the machine. Display and logic board repairs vary by model. We provide a diagnostic and a clear quote before starting any work. No surprises. Call 01334 478866 for a quote.

Frequently Asked Questions

Can you upgrade my old iMac to make it faster?

Almost certainly, yes. The single most impactful upgrade for any iMac with a mechanical hard drive is replacing it with an SSD. A 2012 or 2013 iMac with an SSD boots in seconds instead of minutes, opens applications instantly, and feels like a completely different machine. We can also upgrade RAM in models that support it. If your iMac is still running well but just feels slow, an upgrade is often better value than buying new.

My iMac is showing a folder with a question mark. What does that mean?

The flashing folder with a question mark means your iMac cannot find a bootable operating system. This usually indicates a failed hard drive or SSD, though it can also be caused by a corrupted macOS installation or a loose drive cable. We diagnose the root cause. If the drive has failed, we replace it and recover your data if possible. If the operating system is corrupted, we can often repair or reinstall it without losing your files.

Is it worth repairing a 10-year-old iMac?

It depends on what you use it for. A 2014 or 2015 iMac with an SSD upgrade can still handle web browsing, email, documents, photo management, and even light video editing perfectly well. If you need to run the latest macOS version or professional creative software, an older machine may not be supported. We will always give you an honest assessment of whether a repair makes financial sense for your specific situation.

Can I bring my iMac to you, or do you offer collection?

You are welcome to bring your iMac to our workshop at 1 City Rd. We know they are heavy and awkward to carry. A 27-inch iMac weighs about 9 kilograms. So if transport is difficult, give us a call and we can discuss options. Many customers in St Andrews find it manageable with a short drive and a careful carry.

Can you upgrade my iMac's RAM or storage at the same time?

Absolutely. If we are already inside the machine for a repair, adding an SSD upgrade or RAM expansion at the same time makes perfect sense. It saves you a second visit and a second labour charge. We regularly combine repairs with upgrades, especially for older iMacs that are still mechanically sound but need a performance boost. Let us know what you are interested in when you bring it in, or call 01334 478866 to discuss options.

Is it worth repairing an older iMac?

For many users, yes. An iMac from 2015 or later with an SSD and sufficient RAM is still a very capable machine for everyday tasks, office work, and even creative projects. The 27-inch Retina 5K display alone is something you would pay over a thousand pounds for in a standalone monitor. If the repair cost is reasonable relative to the machine’s remaining useful life, it often makes more sense to fix it than to replace it. We will give you a straight answer based on your specific model and the fault.

Can you repair the iMac's built-in speakers or camera?

Yes, we can. The iMac’s speakers and FaceTime camera are internal components that can fail or degrade over time. Speaker repairs typically involve replacing the speaker modules inside the chassis. Camera issues can be related to the camera module itself or the display cable that carries the signal. We diagnose the specific fault and replace the affected component. These are less common repairs, but we have the parts access and experience to handle them.
