Jude Quartson-Mochrie – Ancient iMac Revival
February 20, 2026
Jude was experiencing extreme technical frustration and needed a functional 2013 iMac restored to its former glory.
My goal was to offer a cost-effective solution by optimising the performance and storage efficiency of the existing machine rather than purchasing new hardware.
The Challenge
System Corruption: A large segment of the 1 TB hard drive was corrupted, erroneously categorising 700 GB as “Other” and leaving only 3 GB of usable space.
Boot Failures: The iMac was unable to enter standard Recovery Mode, preventing a simple factory reset.
Resource Constraints: The client had a strict budget and initial reservations regarding the time required for a complex repair.
Data Scale: Despite the system errors, approximately 300 GB of critical client data required a 12-hour backup process before any repair could begin.
The Solution
I implemented a multi-stage recovery strategy that combined deep technical troubleshooting with proactive system optimisation:
Bespoke Recovery Media: Created a custom bootable Mac OS recovery USB stick to bypass the corrupted onboard recovery partition.
Complete System Rebuild: Executed a full system wipe and Mac OS reinstallation after reformatting the USB stick to resolve compatibility issues.
Intelligent Data Migration: Performed a meticulous two-stage migration to restore 300 GB of data while ensuring the corrupted “Other” files were purged.
Cloud & Security Optimisation: Streamlined the software environment by migrating Dropbox files to iCloud and removing resource-heavy applications like Avast antivirus.
The Result
Jude expressed deep gratitude for the extensive support, acknowledging the excellent value they received for the fixed-cost repair.
The project successfully reclaimed 700 GB of storage and resolved all performance lag.
By the final session, the iMac was fully synchronised with iCloud, and the client was trained on how to manage their files across their iPad and desktop seamlessly.
“Our ‘ancient’ iMac had been running painfully slowly for ages and every day it was frustrating to use. Charlie was incredibly patient and methodical. He took the time to work through what was going on, did a factory reset to properly clear things out, and then set everything back up so the computer was running normally again. He was always willing to clarify questions and explain what he was doing in plain English. His patience, good natured manner, knowledge and perseverance really stood out for us.
The impact was huge! We can use our computer properly again without constant fire-fighting. Instead of feeling like hard work, it’s back to being a tool that helps rather than hinders and we feel relieved, less stressed and more positive about using it day to day.
We are feeling very confident with our equipment because all the little obstacles and the background frustration with the machine have gone. Charlie removed the sticking points and explored the underlying issues, whilst also reviewing our entire setup (storage, backups, iCloud syncing, email etc.). Everything now works seamlessly together across different devices and feels smoother and more reliable.
Whilst carefully managing our expectations, Charlie was prepared to do whatever it took to sort out our problems. He didn’t shortcut the process and although it may have taken longer than expected, it was absolutely worthwhile for the result, which was far better than we’d expected.”
