What Is a MacBook Pro Logic Board Fault?
The logic board is the main circuit board inside your MacBook Pro. Every component in the machine connects to it — the processor, memory, storage, display, USB-C ports, battery, fans, and keyboard. When the logic board fails, the effects range from a completely dead machine to subtle problems like random shutdowns, a flickering screen, or a port that stopped working after a bump.
Most people hear “logic board fault” and assume the machine is done. It is usually not. Logic board failures are almost always caused by a single failed component — one chip, one capacitor, one damaged trace. A microsoldering repair replaces that specific component under a stereo microscope, restoring the board to full function. The cost is a fraction of a new board or a new machine.
Apple does not offer component-level repair — they replace the entire board, which starts at R 15,000 and can exceed R 35,000 for newer models. We repair the component. Same result, fraction of the cost.
Common Symptoms of a Logic Board Problem
- →MacBook Pro will not turn on — no fan, no light, no response
- →Turns on but screen stays black (no display at all)
- →Random shutdowns, especially under load
- →Kernel panics — repeated crashes with a restart message
- →GPU artifacts — coloured bars, flickering pixels, distorted image
- →USB-C ports not charging or not recognising accessories
- →Charging works on one port but not the other
- →Fan runs at full speed constantly, even at idle
- →Touch Bar stops responding or shows nothing
- →MacBook Pro restarts after liquid exposure
If your MacBook Pro is showing any of these symptoms, bring it in or send us a WhatsApp message. The diagnostic is always free.

Our Repair Process
Every MacBook Pro logic board repair follows the same process. No surprises, no hidden costs, no work done without your explicit approval.
Free Diagnostic
We inspect the board under microscope. Power rail testing, short-circuit mapping, and component identification. No charge, no obligation. Completed within 24 hours.
Written Quote
You receive a clear quote covering the specific fault, parts needed, labour, and a completion estimate. No ambiguous "from" pricing at this stage — it is a fixed quote.
Your Approval
We begin work only after you approve the quote. If you decline, you walk away paying nothing. The machine is returned exactly as received.
Component-Level Repair
Our technician uses a Hakko FM-204 hot air station, Leica stereo microscope, and JBC soldering iron to replace the specific failed component. We reflow solder, replace ICs, and repair traces as needed.
Multi-Stage Testing
Before closing the machine: power-on test, full charge cycle, display output check, USB-C port enumeration, thermal monitoring under load, and SMC/T2 validation on applicable models.
Collection or Delivery
You collect from Hyde Park or we arrange secure courier delivery across Johannesburg. Most repairs completed within 3–5 business days from approval.
Typical turnaround
Most MacBook Pro logic board repairs are completed within 3–5 business days from the point of approval. Simple repairs (USB-C, backlight, power fuse) are often completed in 48–72 hours. Complex jobs such as multi-component liquid damage are quoted with a specific timeline.
MacBook Pro Model Compatibility
We repair all MacBook Pro models from 2015 onwards, covering both Intel and Apple Silicon generations. The repair scope differs between Intel and M-series boards — see the table below.
| Year | Model | Chip | Repair Scope |
|---|---|---|---|
| 2015–2017 | MacBook Pro 13" & 15" | Intel Core i5/i7 | Full component repair — most faults repairable |
| 2016–2019 | MacBook Pro 13" & 15" (Touch Bar) | Intel Core i5/i7/i9 | Full repair — Touch Bar, GPU, USB-C, power circuits |
| 2019–2020 | MacBook Pro 13" (Intel) | Intel Core i5/i7 | Full component repair |
| 2019–2020 | MacBook Pro 16" (Intel) | Intel Core i7/i9 | Full repair — discrete AMD GPU reballable |
| 2020 | MacBook Pro 13" (M1) | Apple M1 | Surrounding components repaired — SoC cannot be replaced |
| 2021 | MacBook Pro 14" & 16" (M1 Pro/Max) | Apple M1 Pro / M1 Max | Power management, USB-C controllers, display circuits repairable |
| 2022 | MacBook Pro 13" (M2) | Apple M2 | Surrounding components repaired — SoC cannot be replaced |
| 2023 | MacBook Pro 14" & 16" (M2 Pro/Max) | Apple M2 Pro / M2 Max | Board-level repair for surrounding components |
| 2023–2024 | MacBook Pro 14" & 16" (M3 / M3 Pro / M3 Max) | Apple M3 family | Power delivery, USB-C IC, display path — all repairable |
Note on Apple Silicon (M1/M2/M3)
On M-series MacBook Pros, the processor, GPU, RAM, and Neural Engine are integrated into a single chip (the SoC). This chip cannot be replaced individually — it is bonded to the board at manufacturing. However, the majority of MacBook Pro M-series failures occur in the surrounding components: USB-C controllers, power management ICs, charging path components, backlight drivers, and board traces. All of these are repairable. We will tell you clearly during the diagnostic if the fault is in the SoC itself (rare) or in a repairable surrounding component (common).

💡 Price comparison: Some Johannesburg repair shops charge R 4,999 or more for MacBook Pro logic board repair. ZA Support starts from R 1,800 — with a 12-month warranty and No Fix No Fee guarantee included.
Why Choose ZA Support for MacBook Pro Logic Board Repair?
There are other repair shops in Johannesburg. Here is what separates us from them — and why it matters when you are trusting someone with your MacBook Pro logic board.
4.9 Stars — 120+ Reviews
Verified Google reviews from clients across Johannesburg. We do not cherry-pick — our review profile is public and unfiltered.
14 Years of Apple Repair
Founded in 2012, we have been repairing MacBook logic boards longer than most shops in JHB have been open. Over 3,000 repairs completed.
12-Month Warranty
Our warranty period is 12 months on every repaired component. The industry standard in JHB is 1–3 months. We stand behind our work.
No Fix No Fee — No Exceptions
If we cannot fix it, you pay nothing. We are one of the only repair specialists in Johannesburg offering this unconditionally on logic board repairs.
Component-level repair — not just board replacement
Most repair shops in Johannesburg only offer board replacement — they swap the entire logic board for a new or refurbished one. This is expensive (R 8,000+) and often unnecessary. ZA Support performs component-level microsoldering: we identify and replace the specific failed chip or component on your existing board. Your data stays put, your Touch ID pairing is preserved, and you get your machine back at 60–80% less than a board replacement would cost. We have the equipment, the training, and the track record to do this on every MacBook Pro model from 2015 to 2024.
