I recently acquired a used Mac Pro from late 2013 (MacPro 6,1), and so far, the machine seems to be in excellent cosmetic condition. All internal hardware appears to be functioning well, except for a peculiar issue with the port lights located on the rear panel.
When I power on the machine, the lights flicker on briefly; however, they do not illuminate if I move or turn the system. This has raised concerns about a possible fault with the internal accelerometer sensor.
Despite my worries, the overall condition of the Mac Pro suggests that it hasn’t endured significant physical abuse by the previous owner. I’ve also noted that the seller utilized OpenCore Legacy Patcher to install macOS Sequoia on the device, which raises the possibility that this problem could be software-related.
Unfortunately, I have not been able to find any information online regarding troubleshooting the port lights issue. Furthermore, the seller claimed that the machine has all stock components and has never undergone any servicing.
As I no longer have contact with them for additional insights or support, Iām reaching out for guidance. If anyone has encountered a similar issue or has experience troubleshooting this type of problem, I would greatly appreciate any helpful steps or suggestions.
Understanding whether this is primarily a software conflict, an accelerometer sensor issue, or something else entirely would be invaluable in addressing this concern. Thank you in advance for any assistance you can provide.
