MacBook Air Won't Start Into macOS — Failed SSD, Putney SW15
A MacBook Air in Putney SW15 wouldn't start into macOS. We diagnosed a failed internal SSD, fitted a replacement drive and reinstalled macOS to get it working.
Specialist Mac Repairs from Apple-Experienced Technicians
Last updated: August 2026
Whether it's a MacBook Pro with a failed logic board, an iMac that won't boot, or a Mac mini with storage issues, we diagnose and repair Apple hardware properly — Intel and Apple Silicon alike. Repairs are carried out at our Putney workshop in South West London, with drop-off, collection and same-day options for many faults. You get a clear diagnosis and an itemised quote before any work starts, and we'll tell you honestly when a repair isn't worth the money.
The work we carry out is covered by a 90-day warranty. If the same fault comes back inside that window, we put it right.
We collect and return across South West London at no charge, so you do not have to make the trip to get your machine looked at.
Screens, batteries, keyboards, RAM and SSDs for the models we see most are on the shelf at our Putney workshop, so the usual jobs are not waiting on a supplier.
Same-day turnaround is available on many jobs — ask when you book and we will confirm availability and any additional cost before we start.
3,400+ MacBook repair jobs logged since 2009 — 23% of our current workshop intake. Median turnaround right now: 5 days, with 33% of invoiced jobs back within two.

"My MacBook Pro had a failed logic board. PC Macgicians diagnosed the issue quickly and repaired it for half what Apple quoted. Excellent work!"

"Spilled tea on my MacBook Air. They cleaned it thoroughly, replaced the damaged keyboard, and recovered all my data. Can't recommend them enough."

"My old 2015 iMac was running terribly slow. They upgraded it with an SSD and it's like a new machine. Should have done this years ago!"

Mac diagnostics require specialist knowledge and tools. Here's how we approach it:
We explain everything in plain English and give you options before starting any work.
These are the Mac repairs we handle most frequently:
Screen replacements
Retina displays for MacBook Air, MacBook Pro, and iMac. We handle the delicate process carefully to avoid damage.
Battery replacements
Swollen or depleted batteries in MacBooks. We use quality cells and calibrate properly after installation.
Keyboard repairs
Including the notorious butterfly keyboards. We can replace individual keys or entire top cases.
Logic board repairs
Component-level repairs for power issues, no display, and other board-level faults.
SSD upgrades
Upgrade older Macs with fast NVMe storage for dramatically improved performance.
The Pro carries more heat, more power and a bigger battery than the Air, and its failure patterns follow directly from that:
Thermal throttling and constant fan noise
A Pro under sustained load — video, Xcode, large photo libraries — depends on clear vents and thermal compound that has not dried out. Once it has, the machine slows down under exactly the workload it was bought for, and the fans never settle.
Battery swelling
A swollen cell presses upwards against the trackpad, so the first sign is often a trackpad that clicks oddly or stops clicking altogether, or a case that no longer sits flat on a desk. This is a stop-using-it fault rather than a live-with-it one and wants replacing promptly.
Display cable and backlight failures
On 2016 and 2017 13-inch models a thin display flex cable passes over the hinge and wears with opening and closing. It shows up as uneven bright bands along the bottom of the screen, or a backlight that cuts out past a certain opening angle.
Discrete graphics faults
Pros fitted with a separate graphics chip can develop artefacts, distorted output, a black screen with the machine still running, or crashes under graphics load. These are board-level faults — there is no graphics card to swap in a MacBook.
Keyboard and top case work
Butterfly keyboards from the 2016 to 2019 era fail on individual keys and are famously sensitive to a single crumb. The later scissor keyboards behave far better, but any Pro keyboard takes a spill badly because of what sits directly beneath it.
USB-C and Thunderbolt port wear
When the charger and every accessory share the same handful of ports, wear and knocks accumulate. A machine that only charges when the cable is held at a certain angle is a port repair, not a cable to replace.
Apple has run service programmes covering some of these faults on specific models — the 13-inch display backlight programme, for example, ran to five years from first retail sale and has since closed. Eligibility depends entirely on the model and its age, so it is always worth checking with Apple before paying anybody, ourselves included.
The Air is thinner, cooler and simpler than the Pro, and it fails in a noticeably different set of ways:
Keyboard faults
The 2018 and 2019 Airs used the butterfly mechanism and inherited its problems — repeating keys, dead keys, keys that need a deliberate hit. Airs from 2020 onwards use a much more reliable scissor keyboard, though any Air takes a liquid spill straight through it.
Battery life falling off a cliff
Airs get carried everywhere and cycled hard. Once the cycle count catches up, runtime tends to collapse quickly rather than taper. A replacement battery is usually the cheapest way to make an otherwise healthy Air useful again.
Storage that is slow because it is full
A 128GB Air running macOS, iCloud sync and a photo library sits permanently near capacity, and a nearly full drive is a slow drive. On Airs from roughly 2013 to 2017 the blade SSD can be replaced with something larger and faster. From 2018 onwards the storage is soldered, so the answer is housekeeping and external storage instead.
M-series Airs have no fan at all
The M1, M2 and later Airs are entirely fanless, so noise from one is never a fan fault — it is coming from somewhere else, or the machine is not an Air. What they do instead is throttle quietly during long sustained work, which is designed behaviour rather than a fault.
Hinges, lids and cracked panels
Thin lids and full bags do not mix. Cracked panels, pressure marks across the display and lids closed onto a pen or a cable are routine Air repairs, and the panel is usually replaceable without touching anything else.
Liquid damage reaches the board fast
There is very little space between the keyboard and the logic board on an Air, so a spill arrives at the important parts almost immediately. How quickly the machine is powered down and brought in matters far more than how much went in.
For an out-of-warranty Air the economics are usually straightforward: a battery, keyboard or screen is well worth doing on a machine that still runs a current version of macOS, and much harder to justify on one that does not.
Apple Silicon Macs (M1 onwards) present unique repair challenges:

iMac 21-inch in Putney SW15 needed an OS refresh with the user's photo library preserved. We imaged the photos to USB, ran a clean macOS install, and restored the photos to the rebuilt system.
