Professional Apple Desktop & Workstation Repairs

Mac Pro Repairs

Professional Mac Pro diagnostics and repair for Intel and Apple silicon Mac Pro systems, including tower, rack and workstation configurations. We deal with power faults, startup failures, macOS problems, graphics, storage, memory, thermal issues, PCIe expansion, Thunderbolt, networking, peripherals and complex intermittent faults.

Mac Pro systems vary considerably by generation. We work with Intel Mac Pro models, including older tower systems, the 2013 cylindrical Mac Pro and the 2019 tower, as well as Apple silicon Mac Pro systems including the M2 Ultra generation. Component availability, upgradeability, PCIe support and repair options depend on the exact model.

Mac Pro fault finder

Select every symptom that applies to your Mac Pro. You can select more than one fault in each category. If you are unsure, select the closest description and explain what is happening in the notes at the end of the form.

1. Power, Startup & No-Response Faults

Mac Pro will not power on

No response when the power button is pressed

Powers on but immediately switches off

Starts intermittently

Fans start but there is no usable display

Power appears normal but system does not complete startup

Unexpected shutdowns

Unexpected restarts

Mac Pro becomes completely unresponsive

Power fault began after moving the workstation

Power fault began after hardware was installed or removed

Power fault is intermittent and difficult to reproduce

Important: Do not repeatedly power-cycle a system that is making unusual electrical noises, showing signs of burning, or has suffered liquid or physical damage. Tell us what happened before further testing.

2. macOS Boot & Operating System Problems

Stuck at Apple logo

Stuck on progress bar

Repeatedly restarts during boot

Kernel panic or repeated kernel panics

macOS will not load after an update

Applications repeatedly crash

System freezes or becomes unresponsive

Very slow macOS performance

Desktop or Finder repeatedly crashes

System settings or services behaving unexpectedly

macOS installation or recovery problem

Operating-system faults can be caused by software, storage failure, incompatible hardware, corrupted system files or other underlying hardware problems. We diagnose the cause rather than assuming that reinstalling macOS will solve the fault.

3. Display, GPU & Graphics Output

No picture on connected display

Intermittent display output

Display flickering

Display showing artefacts

Incorrect resolution or refresh-rate behaviour

Graphics performance suddenly reduced

GPU crashes under load

Graphics-related kernel panic

External display works intermittently

Multiple-display setup not working correctly

PCIe graphics card not detected

Graphics fault began after macOS update

GPU becomes excessively hot

Professional graphics application crashes

Model warning: Graphics architecture differs substantially between Intel Mac Pro systems and Apple silicon Mac Pro systems. PCIe graphics-card support is model and macOS dependent. Apple silicon Mac Pro uses an integrated GPU architecture rather than a conventional replaceable discrete GPU in the same way as compatible Intel tower configurations.

4. Storage, SSD & Data Problems

Internal storage not detected

External storage not detected

Storage intermittently disconnects

Very slow storage performance

Disk Utility reports errors

Mac Pro cannot find the startup disk

Storage is nearly full

Files are disappearing or becoming inaccessible

Drive makes unusual noises

Storage fault followed a system crash

Storage fault followed a hardware installation

Data access or recovery concern

Data warning: Repair work does not guarantee recovery of data from failed storage. If important files are involved, tell us before approving work so data-preservation considerations can be taken into account.

5. Memory / ECC RAM & Performance

Memory errors reported

ECC memory warnings

System crashes during heavy workloads

Applications crash when memory usage is high

Installed memory is not detected correctly

Memory configuration changed before the fault

System becomes unstable after RAM upgrade

Unexpected memory-related kernel panic

Performance is lower than expected after memory changes

Memory configuration needs assessment

Model warning: Intel Mac Pro models may use removable and upgradeable memory depending on the generation. Apple silicon Mac Pro memory is integrated into the system architecture and is not a conventional user-replaceable RAM module.

6. CPU, Apple Silicon & Thermal Performance

Processor performance suddenly reduced

System slows heavily under CPU load

CPU-intensive applications crash

Unexpected thermal throttling

System becomes unstable when under sustained workload

Performance changed after hardware or software changes

Apple silicon performance issue

Intel processor performance issue

Professional workload repeatedly causes instability

System reports thermal or processor-related warnings

Mac Pro performance problems can involve CPU load, cooling, storage, memory, GPU workload, background processes or incompatible hardware. We investigate the complete system rather than treating every performance complaint as a CPU fault.

7. Fans, Cooling & Overheating

Fans constantly running at high speed

Fans unusually loud

Fan not operating correctly

System overheating

Thermal throttling

Cooling problem after cleaning or maintenance

Temperature rises rapidly under load

Mac Pro shuts down because of heat

Dust or airflow restriction suspected

Cooling fault appeared after hardware installation

Professional workstation cooling faults should not be ignored. Continued operation at excessive temperatures can cause instability and performance reduction and may contribute to further hardware damage.

8. PCIe Slots, Expansion Cards & Internal Hardware

PCIe card not detected

PCIe card works intermittently

Expansion card causes kernel panic

Expansion card stopped working after macOS update

PCIe storage card problem

PCIe networking card problem

PCIe audio or professional media card problem

PCIe graphics card problem

Expansion hardware causes startup failure

New hardware is incompatible or unsupported

PCIe slot itself may be faulty

Fault began after opening the Mac Pro

Compatibility warning: PCIe compatibility varies by Mac Pro generation, card, firmware and macOS version. A PCIe card that works in one Mac Pro is not automatically supported in another.

9. Thunderbolt, USB & Peripheral Ports

Thunderbolt device not detected

USB device not detected

USB-C device not detected

USB-A device not detected

Thunderbolt connection repeatedly disconnects

USB connection repeatedly disconnects

External dock not working

Network faults can originate from the Mac Pro, installed networking hardware, macOS configuration, drivers, cables, switches or wider network infrastructure. We establish whether the fault is local to the Mac Pro.

11. Audio & Professional AV

No audio output

Audio output intermittently disappears

External audio interface not detected

USB audio device not detected

Thunderbolt audio interface problem

Professional audio application crashes

Audio dropouts or interruptions

Incorrect audio device selected or unavailable

External hard drive not detected

RAID or storage enclosure problem

Docking station not working correctly

External monitor dock problem

Professional capture hardware not detected

External interface repeatedly disconnects

Where several external devices fail together, the fault may be with the Mac Pro port, controller, dock, operating system or power delivery rather than every individual peripheral.

13. Recovery, Firmware & Security

Recovery mode will not start

Internet Recovery problem

Startup security setting problem

Firmware-related startup problem

Firmware update failed

System does not recognise expected startup options

Activation or ownership issue

FileVault or encrypted-storage access issue

Administrator access problem

Mac Pro generation matters. A fault or component that is repairable or upgradeable on an Intel Mac Pro may not have the same repair route on an Apple silicon Mac Pro. We identify the exact model before recommending parts or work.

Important repair limitation: We do not provide board-level soldering, micro-soldering or logic-board component-level repair. If a fault requires work outside our repair capability, we will explain this rather than proceeding with unsuitable work.
