The SMC is responsible for managing low-level functions such as power management, keyboard backlighting, fan speed, and other hardware components. Here's a general overview of what happens during an SMC reset: 1. **Power Disruption**: First, you'll need to shut down your MacBook Pro completely. 2. **Battery Unplugging**: If you have a model with a removable battery, you'll need to physically unplug the battery for a brief moment.
