Azizi Technologies' broad Dubai MacBook troubleshooting archive. Real workshop-tested solutions for dual external monitor issues on M4 Pro, trackpad clicking on M4 Air, speaker crackling fixes on M4 Pro, slow download speeds on M4, M3 24GB vs M4 16GB RAM choice, choosing between Pro 14 and Air 13, external CD/drive recognition, unstable trackpads, and risk of cracked Adobe software. Comprehensive Q&A from our certified Apple technicians.
Quick answer
Azizi Technologies runs a MacBook troubleshooting workshop in Dubai covering M1 through M4 machines. The most common faults our engineers see are external display detection failures, trackpad click and vibration issues, speaker distortion, and slow network throughput. Every diagnosis is free and quoted in writing before any work begins.
M4 Pro will not drive two external monitors
The M4 base chip supports fewer external displays than the Pro variant. Cable standard and dock bandwidth matter as much as the chip.
Trackpad clicks and vibrates while scrolling
Usually a Taptic Engine or firmware calibration fault rather than a broken trackpad, which changes the repair path completely.
Internal speakers crackle but external audio is fine
Points to the internal amplifier or a driver conflict, not the speaker cone. Worth testing before any part is ordered.
Download speeds far below the line rate
Often Wi-Fi band steering or a DNS issue rather than the Mac. We test against a wired baseline first.
Choosing between more RAM and a newer chip
M3 with 24GB beats M4 with 16GB on memory-bound work and loses on single-core tasks. It depends entirely on the workload.
External optical drive not recognised
Usually a power delivery limit on the USB port rather than a dead drive.
| Symptom | What it usually means |
|---|---|
| Screen works, external display does not | Cable standard or chip display limit, rarely a hardware fault |
| Trackpad feels alive when scrolling | Taptic Engine calibration, often fixable without parts |
| Audio distorts only on internal speakers | Amplifier or driver, not the speaker itself |
| Fans loud with nothing running | Background indexing or a failing thermal sensor |
| Machine slow only on large files | Memory pressure, which a RAM upgrade cannot fix on Apple Silicon |
More RAM on the older chip, or less RAM on the newer one? It depends on your workload.
Both monitors connected but only one shows up? Here's how to get dual display working on M4 Pro.
Both monitors connected, only one shows up - here's how to get all displays running.
Worked yesterday, broken today? Here's what changed and how to restore it.
Phantom clicks under your fingers? That's the Taptic Engine - and there's a quick fix.
Plan says 1 Gbps but Speedtest shows 80? Here's how to find the bottleneck.
Air for portability and price, Pro for sustained performance and a better screen - here's how to decide.
Cracked Photoshop seems harmless - until you realise what's actually running on your Mac.
Internal speakers garbled but Bluetooth and headphones are clear? It's usually one of three things.
External CD drive plugged in but Finder doesn't see it? Try these fixes in order.

It depends on the chip. Base M1, M2 and M3 chips drive one external display natively. Pro and Max variants drive two or more. Docks using DisplayLink can add displays to base chips, at some cost to smoothness and CPU load.
Usually yes. When external audio is clean, the fault is almost always the internal amplifier or a software driver rather than the speaker. That is a far smaller job than a full audio assembly replacement, and we confirm which it is before quoting.
Yes. Azizi Technologies is an independent repair shop, not an Apple Authorised Service Provider, which means we can work on logic boards at component level where an authorised provider would replace the whole board.
