About this part
The Single Processor Board (Apple part number 661-5707) is a genuine Apple part that fits the Mac Pro Mid 2012 and Mac Pro Server Mid 2012. The logic board carries the processor, memory, power management and every connector, so it decides whether the Mac powers on at all.
Before you order, match the model identifier on your Mac (Apple menu, About This Mac, System Report) to the identifier listed for this part: MacPro5,1.
Signs the logic board needs replacing
- No power, no chime, or a black screen even though the charger light is on
- Random shutdowns, restart loops, or kernel panics that survive a clean macOS install
- Liquid damage, corrosion, or a burnt smell near the board
- Ports, Wi-Fi, or USB-C charging that stop working all at once
Not sure the logic board is the real cause? Our logic board repair service starts with a full diagnosis, and we can install this genuine Apple part for you through our Mac Pro repair service, in our Tampa shop or by mail-in repair from anywhere in the US.
