iMac M3 & M4 Repair
Bournemouth, Dorset & UK-Wide Service
Expert repair for the latest 24-inch iMac with M3 and M4 chips. Screen replacement, nanotexture display repair, power faults, Thunderbolt port fixes, and more.
The Latest iMac Generation: Powerful, Beautiful, Repairable
The iMac M3 (late 2023) and iMac M4 (2024) represent the cutting edge of Apple's desktop lineup. Building on the revolutionary design introduced with the M1, these machines deliver substantially improved performance through next-generation Apple Silicon while maintaining the elegant 24-inch 4.5K Retina display and ultra-thin chassis that define the modern iMac.
The M4 model introduces several notable upgrades: a 12MP Centre Stage camera with Desk View, Thunderbolt 4 connectivity, support for Apple Intelligence, and an optional nanotexture display that dramatically reduces reflections in bright environments. Both models feature Wi-Fi 6E for faster wireless performance and up to 32GB of unified memory.
As with all Apple Silicon Macs, these machines feature soldered RAM and storage, meaning professional repair expertise is essential. At RevivaTech, we have invested in the specialised tools and training needed to service these latest-generation machines. Whether you are in Bournemouth, elsewhere in Dorset, or anywhere across the UK, we deliver fast, reliable repairs with a full 12-month warranty.

Common iMac M3 & M4 Problems We Fix
Experiencing any of these issues? Book a free diagnostic and we will identify the exact cause.
Display Artefacts or Dead Pixels
The 24-inch 4.5K Retina display on iMac M3 and M4 can develop dead pixels, colour banding, or green/pink tint issues. These are typically caused by panel defects or T-CON board failure. We replace the display with a factory-calibrated panel and verify True Tone functionality post-repair.
Power Supply Failures
Power supply problems can manifest as the iMac refusing to turn on, random shutdowns, or the MagSafe light not illuminating. Causes include failed capacitors in the power adapter, damaged MagSafe connectors, or internal voltage regulation faults. Our technicians test the complete power chain to isolate the fault.
Thunderbolt Port Failures
With Thunderbolt 4 ports serving as the primary connectivity for external displays, fast storage, and peripherals, port failure is particularly disruptive. Bent pins, liquid corrosion, and ESD damage are common causes. We replace individual port assemblies using micro-soldering techniques.
Overheating Under Heavy Load
While the M3 and M4 chips are highly efficient, sustained heavy workloads such as video rendering or 3D modelling can cause thermal throttling. Dust accumulation, dried thermal paste, or fan bearing wear can worsen the problem. We perform thorough thermal maintenance to restore optimal cooling.
Wi-Fi 6E Connectivity Issues
The iMac M3 and M4 support Wi-Fi 6E for faster wireless performance, but antenna cable damage or firmware issues can cause intermittent connectivity, slow speeds, or failure to connect to 6GHz networks. We diagnose and repair the wireless subsystem, including antenna replacement if needed.
Nanotexture Display Damage (M4)
The optional nanotexture glass display on the iMac M4 features a precision-etched anti-reflective coating. This surface is more susceptible to scratching than standard glass if cleaned improperly. Replacement requires sourcing the specific nanotexture panel, which we can obtain for specialist repair.

iMac M3 & M4 Repair FAQs
Common questions about latest-generation iMac repair
How much does an iMac M3 screen replacement cost?
iMac M3 and M4 24-inch screen replacement pricing depends on the specific display panel and configuration required. The nanotexture display option on the M4 is a specialist repair. All repairs include parts, labour, and a 12-month warranty. Contact us for a free, no-obligation quote.
Can you repair the nanotexture display on the iMac M4?
Yes. We are one of the few independent repair providers equipped to source and replace the nanotexture etched glass panel available on the iMac M4. This is a specialist repair due to the sourcing requirements for this unique display type. Contact us for availability and a quote.
How do I get a quote for iMac M3/M4 repair?
Book a free evaluation through our website or contact us directly. We diagnose the issue and provide a transparent, no-obligation quote. For simpler repairs, we can often begin work on the same visit once you approve the quote.
Can you upgrade the RAM in an iMac M3 or M4?
No. Like all Apple Silicon Macs, the unified memory in the iMac M3 and M4 is part of the chip package and cannot be upgraded after manufacture. We recommend selecting the maximum RAM configuration at purchase for demanding workloads.
What is the difference between iMac M3 and iMac M4?
The iMac M4 (2024) features the M4 chip with improved CPU and GPU performance, a 12MP Centre Stage camera with Desk View, Thunderbolt 4 ports, an optional nanotexture display, and support for Apple Intelligence. The M3 model (late 2023) uses the M3 chip with a 1080p camera, and standard glass display options.
Do you repair iMac M3/M4 models refused by Apple?
Absolutely. We frequently repair machines that Apple has quoted for a full logic board replacement. Our component-level repair capabilities let us fix individual circuits, often saving significantly compared to a complete board swap.
How do you handle the adhesive during iMac M3/M4 screen removal?
The 24-inch iMac display is secured with adhesive strips. We use a precision cutting wheel and controlled heat to separate the display without damage, then apply new OEM-grade adhesive strips in a dust-free environment during reassembly. This ensures a factory-quality seal.
Can you recover data from a dead iMac M4?
In most cases, yes. Even when the iMac will not boot, we can often recover data from the integrated SSD using specialised Apple Silicon recovery tools. Because the storage is soldered, conventional drive removal is not possible, making professional recovery essential.
Do you offer a postal repair service for iMac M3/M4?
Yes. We offer fully insured postal repair for customers throughout the UK. We can arrange courier collection from your address, or you can send the iMac to our Bournemouth workshop. The machine is securely packaged and returned upon completion.
Is the iMac M3 still worth repairing in 2026?
Yes. The M3 chip is an excellent performer and Apple continues to deliver macOS updates for it. Repairing a display or fixing a power issue is far more economical than purchasing a replacement machine, especially when the logic board itself is healthy.
Do you provide a warranty on iMac M3/M4 repairs?
Every iMac M3 and M4 repair includes our comprehensive 12-month warranty covering both parts and labour. If the same issue recurs within the warranty period, we re-repair it at no additional cost.
Can you fix liquid-damaged iMac M3 or M4 units?
Yes. We handle liquid damage on the latest Apple Silicon iMacs using ultrasonic cleaning, corrosion removal, and component-level replacement. Success rates vary depending on the extent of damage and how quickly the machine was powered off after the spill.
