Repairs we carry out on the Mac mini M6 and M5 Pro
Power supply repair
A mini PC that shows no signs of life often has a failed external power adapter. We test with a known-good adapter before looking at the board.
Memory
Memory in the Mac mini M6 and M5 Pro is part of the Apple silicon chip and cannot be changed after purchase.
macOS reinstall and repair
We reinstall macOS, migrate data, and can revive or restore the firmware in DFU mode from a second Mac when an update has left the machine unresponsive.
Storage
Storage on the Mac mini M6 and M5 Pro is soldered and cannot be upgraded. We can help with external storage, clearing space, or moving to a new machine.
We also carry out logic board repair, overheating and fan repair, macOS reinstallation on the Mac mini M6 and M5 Pro, along with no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
Known issues with the Mac mini M6 and M5 Pro range
- The 2018 Mac mini pairs soldered, T2-encrypted storage with upgradeable memory; the 2014 model is the reverse, with soldered memory.
- Apple silicon Mac mini models have both storage and memory on the logic board.
- The power supply is internal, so a mini that is completely dead may need a power supply and not a logic board.
Data recovery from the Mac mini M6 and M5 Pro
The SSD in the Mac mini M6 and M5 Pro is soldered and hardware-encrypted, so there is no drive to remove. If the Mac is dead, data recovery means repairing the logic board far enough to start it and copy the data off. If you have a Time Machine or iCloud backup, tell us, as that may be the quicker route.

Questions
Can the SSD or memory in the Mac mini M6 and M5 Pro be upgraded?
The storage is soldered and cannot be upgraded. Memory is part of the chip and cannot be changed.
My Mac mini M6 and M5 Pro will not turn on. Is my data lost?
Not necessarily, but the storage is on the main board, so the board has to be repaired far enough to read it. Do not keep trying to power it on, and tell us about any backups you have.
Is my Mac mini M6 and M5 Pro still under warranty?
It may be. Machines from 2026 are often still inside the manufacturer's warranty, which covers faults but not accidental damage such as a cracked screen or a spill. Check that first; we repair what the warranty does not cover.
Where do I find the model number on my Mac?
The model number, an A followed by four digits, is printed in small text on the underside. Apple menu > About This Mac shows the year. For this model, look for A3534 or A3535.
