Are you experiencing issues with your Mac’s display settings, time and date, or other system preferences? If so, you may need to zap the PRAM (Parameter RAM) to reset these settings to their default values. In this article, we’ll explore what PRAM is, why you might need to zap it, and provide a step-by-step guide on how to do so.
What Is PRAM And Why Do You Need To Zap It?
PRAM (Parameter RAM) is a small amount of memory on your Mac that stores system settings, such as:

These settings are stored in PRAM so that they can be accessed quickly by the system. However, sometimes PRAM can become corrupted, leading to issues with these settings. This is where zapping the PRAM comes in.
Zapping the PRAM resets these settings to their default values, which can often resolve issues related to display settings, time and date, and other system preferences. It’s a simple process that can be done in just a few steps.
