Over a period of time, you usually notice that your Mac starts behaving weird. This weirdness might not be resolved by following basic troubleshooting like restarting your Mac. For this, you might need to go to a deeper level to resolve it.

On the other hand, SMC (System Management Controller) is specifically for Intel-based Macs. SMC controls different things than PRAM. For example, it takes care of your CPU fan, lights on your Mac and keyboard, Power, and System Performance. Resetting PRAM and SMC are the last steps of troubleshooting. So do not do this on a regular basis as a basic troubleshooting.

Although, there is no risk involved in resetting these two, even then have a backup of important stuff on an external drive. Remove speakers and other fancy hardware from your Mac before proceeding with the guide. Please follow the guide in the sequence, and not jump directly to reset SMC.
