What I do

Diagnosis

04
  • Hardware and software health check
  • Find the fault — and the cause
  • What the machine is, and the most it can become
  • Honest verdict: fix it or retire it

Upgrades

03
  • SSD swap
  • RAM to the maximum
  • CPU and power supply on desktops

Repairs

05
  • Battery replacement
  • MacBook Air & Pro keyboard + backlight swaps
  • Broken part replacement
  • Motherboard and component testing
  • Windows, macOS & Linux installs and reinstalls

Clean & cool

02
  • Full internal clean — dust out, fans checked
  • Fresh thermal paste on CPU and GPU
Examples

Start to finish.

All of them now run Linux: fully updated, fans and temperatures under control, tuned for the longest battery life — and they feel new and quick.

MacBook Air 13″ (Early 2015)

Specs
A1466 · Intel Core i5-5250U · 4 GB RAM · Intel HD Graphics 6000
Before
Spanish keyboard, old battery, and a macOS too old to get security updates.
Done
  • Stripped down completely and deep-cleaned — every port included
  • Spanish keyboard swapped for a brand-new UK one, with a new backlight
  • New battery
  • Fresh thermal paste on the CPU
Set up
Linux
Why
The newest macOS this Mac can run no longer gets security updates. Linux does — and it’s built with privacy and security in mind.

MacBook Pro 13″ (Late 2011)

Specs
A1278 · 16 GB RAM · 500 GB SSD
Before
A swollen battery had cracked the trackpad. Outdated macOS, 4 GB RAM and a slow 240 GB hard drive.
Done
  • Swollen battery removed — new battery fitted
  • Cracked trackpad replaced
  • RAM upgraded from 4 GB to 16 GB
  • 240 GB hard drive swapped for a 500 GB SSD
  • Stripped down and cleaned throughout
  • Fresh thermal paste on the CPU
Set up
Linux
Why
This Mac’s last macOS stopped getting updates years ago. Linux is current and secure — and with 16 GB and an SSD, it flies.

MacBook Air 13″ (Mid 2011)

Specs
A1369 · 4 GB RAM
Before
Working fine — just older, with 4 GB RAM and a macOS long out of date.
Done
  • Fresh thermal paste on the CPU
  • Up-to-date system installed and tuned
Set up
Linux
Why
A modern, secure system that stays light on 4 GB — so an older Air keeps going.
