The honest answer is that it depends. We've diagnosed and repaired over 18,000 Apple devices across Johannesburg, and we've learned that "won't turn on" covers everything from a simple power supply failure (fixable in an afternoon for under a thousand rand) to logic board corruption (potentially several thousand). The good news is that our initial assessment, R599, gives you clarity before any major work begins.
Let's walk through what causes this problem, what you can expect to pay, and how we approach these repairs in our workshop.
Why Your Mac Won't Turn On: The Most Common Culprits
Before we talk about cost, you need to understand what's actually broken. In our experience, a Mac that refuses to power up falls into one of several categories, each with different repair implications.
Power supply failure is the most frequent issue we see. The 85W or 96W USB-C adapters wear out, especially in Johannesburg where power surges from load shedding stress equipment. When the power supply dies, your Mac simply won't charge or respond. Replacement adapters start around R899 for a genuine Apple unit, though we sometimes identify faulty charging ports instead, which adds complexity.
Battery degradation looks similar. An older MacBook's battery can lose the ability to hold charge entirely, and in some cases, the machine won't boot without external power. If the battery has swollen, which happens more often in our hot, dry Johannesburg climate, this becomes urgent.
Logic board issues are more serious. Liquid damage, component failure, or firmware corruption can all prevent startup. This is where costs genuinely escalate.
Our R599 assessment includes full diagnostics: we test power delivery, check for visible damage, run firmware recovery, and identify exactly which component has failed. This assessment fee applies toward any repair you approve.
Typical Repair Costs at ZA Support
Here's what clients in the Hyde Park area typically pay for common "won't turn on" scenarios:
Power supply replacement: R899-R1,200 depending on wattage and whether we're replacing a genuine Apple adapter or repairing the charging port itself.
Battery replacement: R1,200-R2,100 for MacBook batteries, including labour. Older MacBook Air models cost less than newer 16-inch Pro units.
Logic board component repair: R1,500-R4,500 if we can identify a single failed component (a capacitor, voltage regulator, or controller IC). This assumes we can source the part and perform microsoldering work safely.
Full logic board replacement: R3,500-R8,500 depending on model. A 2015 MacBook Air logic board costs significantly less than a 2023 M3 Max board.
Liquid damage recovery: If water or coffee has seeped into your machine, diagnosis alone can take 2-3 hours. Repair costs range from R1,200 (if we simply need to clean and dry the board) to R6,000+ if components require replacement.
For context, Apple's own mail-in repair for logic board work typically costs R8,000-R15,000, with 5-7 week turnaround. We usually complete the same work within 2-5 working days, and we back all repairs with a 3-year warranty on parts and labour.
The ZA Support Approach: Transparency First
We've found that the worst part of sending your Mac away for repair isn't the cost, it's the uncertainty. You drop it off and hear nothing for two weeks.
That doesn't happen here. When you bring your Mac to our Hyde Park workshop, we:
For our clients who've experienced load shedding damage or power surges, we also discuss preventative measures. A good quality UPS or surge protector (R400-R800) can save thousands later.
When "Won't Turn On" Is Actually a Simple Fix
Not every startup failure needs expensive repair. We've resolved roughly 3 out of every 10 "won't turn on" calls with software troubleshooting alone, no charge if we fix it in under 30 minutes.
Reset the SMC (System Management Controller). This resolves power delivery issues on Intel Macs and older M1 models remarkably often.
Try DFU restore using Apple's recovery tools. Firmware corruption sometimes looks like a complete power failure.
Check for swelling. If your battery has expanded, it physically prevents the logic board from seating properly. This is urgent, swollen batteries can catch fire.
Inspect the charging port for debris or bent pins.
If none of these work, that's where our workshop steps in. We have specialised equipment: thermal imaging cameras to spot capacitor failures, microscopes for solder joint inspection, and microsoldering tools for component-level repair that most shops simply can't perform.
Choosing the Right Repair Partner
You have three realistic options when your Mac won't turn on:
Apple Authorised Service Provider (like us): Faster turnaround than Apple directly, warranty on parts and labour, direct access to genuine components. Assessment R599, typical repairs R1,200-R5,000.
Apple Direct: Official repair, longest wait (5-7 weeks), higher cost (R8,000-R15,000), but guaranteed compatibility. No local turnaround benefit for Johannesburg clients.
Cheap high street repairs: Quick, cheap initial quote, but often use aftermarket parts, no warranty, and frequently don't solve the underlying issue. We've had clients spend R1,500 on a failed repair, then pay R3,500 to fix what went wrong.
Over 18,000 devices repaired, we've learned that the cheapest option rarely becomes the cheapest option once you factor in repeat visits and part failures.
How to Prepare Before You Bring It In
Book online at zasupport.com/book to secure your assessment slot, or WhatsApp us on 064 529 5863 if you'd prefer to chat first about your specific situation. We're open Monday to Saturday in Hyde Park, and we handle both Intel and Apple Silicon Macs.
What Warranty Covers "Won't Turn On"
If your Mac is under Apple's one-year limited warranty, power-related failures are usually covered, provided there's no liquid damage and you haven't opened the case yourself. We're an Apple Authorised Service Provider, so we can process warranty claims directly.
AppleCare+ (if you purchased it) extends this to three years and covers accidental damage, which is critical if load shedding has caused a power surge to damage your machine.
Out of warranty? That's where our repairs make sense economically. Our 3-year warranty on logic board work gives you genuine peace of mind.
How Quickly Can You Get Your Mac Back?
We understand that your Mac is a tool, not a luxury. Turnaround matters. We prioritise same-week completion for most repairs and keep you updated every step.
For complex liquid damage or rare component failures, we might need to source parts from international suppliers, which can add time. We'll tell you that upfront, no false promises.
Getting Started
Your next step is simple. The R599 assessment tells you exactly what's broken and exactly what it'll cost to fix. That fee applies toward your repair if you proceed.

Frequently Asked Questions
Q: Is the R599 assessment fee worth paying if I'm not sure about the repair?
Yes. For R599, you get a definitive diagnosis and a fixed repair quote. Most clients spend that money and then proceed. Some discover the repair cost is higher than replacing the device, which lets you make an informed decision. Either way, you're not guessing anymore. And if you proceed with the repair, we apply that R599 toward the invoice.
Q: Can you replace my Mac's logic board with a used part to save money?
We can, and we sometimes offer this as an option. A used logic board from a donor machine costs roughly 30-40% less than a new Apple part. The trade-off is that used components carry slightly higher failure risk. We'll fully explain this option and let you choose. Our 3-year warranty applies either way.
Q: How does load shedding in Johannesburg affect Mac failure rates?
Load shedding causes power surges when the grid reconnects. Macs plugged into unprotected outlets are vulnerable, capacitors and voltage regulators can fail. We've seen a 40% increase in surge-related failures since load shedding intensified. A UPS or surge protector (R400-R800) is genuinely worth the investment if you're in Johannesburg.
Q: What if my Mac is still under AppleCare+?
Bring it in with your proof of purchase. We're Apple Authorised, so we can process your claim directly. Accidental damage (liquid, drops) is usually covered. You might pay a small deductible, but most logic board replacements cost you nothing under AppleCare+.
Q: How long do repaired Macs typically last before they fail again?
Our repair data shows that component-level repairs (capacitor replacement, solder rework) have a 95% success rate beyond 24 months. Logic board replacements are essentially as reliable as a new machine. The 3-year warranty reflects our confidence in this durability.
Q: Why is your assessment fee R599 when other shops offer "free diagnosis"?
Free diagnosis usually means a technician spends 10 minutes looking at it, guesses at the problem, and quotes you for the repair. Our R599 assessment is thorough: full power testing, thermal imaging, firmware recovery attempts, component inspection. You get certainty, not guesswork. That certainty is worth R599.
