My Mac mini HDMI port stopped working — can it be repaired?
Yes. HDMI port failure on the Mac mini is most often a controller IC fault rather than physical port damage. We repair the HDMI controller at component level, restoring full display output without replacing the entire logic board. Physical port damage (bent or broken connector) is also repairable by reflowing and replacing the port socket.
My Thunderbolt 3 or 4 port is not detecting devices — is that fixable?
Yes — Thunderbolt controller IC failures are repairable at component level. This is one of the most common faults on the Mac mini 2018 and M-series models. Port not detecting drives, displays, or accessories is usually a controller IC or power delivery circuit fault, not physical damage.
I spilt something on my Mac mini and now the USB ports don't work — is that corrosion?
Most likely yes. Liquid ingress on the Mac mini typically affects the USB-A or USB-C ports first due to their exposed position. We perform ultrasonic cleaning and component-level repair on the affected board area. Bring it in as soon as possible and do not power on — corrosion progresses the longer a wet board stays energised.
My Mac mini 2012 or 2014 has a Thunderbolt 2 port fault — can that be fixed?
Yes. Thunderbolt 2 controller IC faults on older Mac mini models are diagnosable and repairable at component level. The older Thunderbolt 2 standard uses a different controller chip but the same repair approach applies.
Does port repair require replacing the whole logic board?
In most cases no. Port failures on the Mac mini are overwhelmingly IC faults rather than whole-board failures. Component-level repair of the specific controller chip is far less expensive than board replacement and carries the same 6-month warranty.
My Mac mini 2024 front USB-C ports don't charge accessories — what's the fault?
The M4 Mac mini introduced front USB-C ports. No power delivery from these ports is usually a USB-C power delivery controller IC fault. Component-level repair is possible — bring in for a free diagnostic.
How long does Mac mini port repair take?
Port repair typically takes 1–3 business days depending on fault complexity. Same-day turnaround is often possible for straightforward IC faults. We give you a clear timeline on arrival.
Do you offer collection for Mac mini port repair?
Yes — R300 door-to-door collection and return across Gauteng. WhatsApp us on 078 742 4769.
My Mac mini 2018 only has two of its four Thunderbolt ports working — is that a board fault?
The 2018 Mac mini has two Thunderbolt 3 controllers, each managing two ports. If two ports on the same side stop working simultaneously, it almost always points to one controller IC failing. This is an IC-level repair — the failed controller replaced without board swap. Free diagnostic confirms which controller before quoting.
Can you repair the 3.5mm audio jack on a Mac mini?
Yes — 3.5mm audio jack failure is repairable on all Mac mini models. On Intel Mac minis the audio board is a separate small PCB that can be replaced independently from the logic board, making this a straightforward repair.
