Are you experiencing strange behavior with your Mac, such as display issues, audio problems, or sudden shutdowns? One potential solution is to reset the Parameter RAM (P RAM) on your Mac. In this article, we’ll explore what P RAM is, why you might need to reset it, and provide a step-by-step guide on how to do so safely and effectively.
What is Parameter RAM (P RAM)?
Parameter RAM, also known as NVRAM or PRAM, is a small amount of memory that stores various system settings and preferences on your Mac. This information includes:
- Display settings, such as resolution and brightness
- Sound settings, including volume and output device
- Startup disk selection
- Network settings, including Wi-Fi and Ethernet
- Other system preferences, such as keyboard and mouse settings
P RAM is non-volatile, meaning that it retains its data even when your Mac is turned off. This allows your Mac to remember your preferred settings and startup configuration.
Why Reset P RAM?
There are several scenarios where resetting P RAM can be beneficial:
Resolving Display Issues
If you’re experiencing display problems, such as a distorted or blurry screen, resetting P RAM may resolve the issue. This is particularly true if you’ve recently installed new display drivers or updated your operating system.
Troubleshooting Audio Problems
If you’re having trouble with your Mac’s audio, such as no sound or distorted audio, resetting P RAM can help. This can be especially useful if you’ve recently installed new audio drivers or updated your operating system.
Fixing Startup Issues
If your Mac is having trouble starting up or is stuck on a blank screen, resetting P RAM may help. This can be due to a corrupted P RAM storing incorrect startup settings.
Resolving Other System Issues
In some cases, resetting P RAM can help resolve other system issues, such as problems with Wi-Fi or Ethernet connectivity, keyboard and mouse issues, or even issues with your Mac’s clock and calendar.
How to Reset P RAM on a Mac
Resetting P RAM is a relatively simple process, but it’s essential to follow the correct steps to avoid any potential issues.
Shut Down Your Mac
Before resetting P RAM, make sure your Mac is completely shut down. This is important, as you’ll need to press specific keys during the startup process.
Locate the P RAM Reset Keys
The keys used to reset P RAM vary depending on your Mac model:
- For Macs with a removable battery: Command (⌘) + Option (⌥) + P + R
- For Macs without a removable battery (such as newer MacBook models): Power button + Volume down button + Command (⌘) + R
Press the P RAM Reset Keys
Immediately after pressing the power button to turn on your Mac, press and hold the P RAM reset keys. Hold them down for at least 20 seconds, as this allows the P RAM to reset properly.
Release the Keys and Allow Your Mac to Boot
Release the P RAM reset keys and allow your Mac to boot up as usual. Your Mac may take a few moments to load, but it should eventually boot up to the login screen.
Reconfigure Your Settings
After resetting P RAM, you’ll need to reconfigure your system settings and preferences, as they will be lost during the reset process. This includes re-selecting your startup disk, reconfiguring your display and sound settings, and re-entering your network settings.
Tips and Precautions
Before resetting P RAM, keep the following tips and precautions in mind:
Backup Your Data
While resetting P RAM won’t erase your data, it’s always a good idea to backup your important files and data regularly.
Avoid Resetting P RAM During Critical System Updates

What is PRAM on a Mac, and what does it do?
PRAM (Parameter RAM) is a type of non-volatile memory in Mac computers that stores various system settings and preferences. These settings include things like display resolution, time zone, and volume settings. PRAM also stores information about the computer’s hardware configuration, such as the type of graphics card and the amount of RAM installed.
By storing these settings in PRAM, your Mac can quickly access and recall them as needed. This allows your computer to boot up faster and function more efficiently. However, sometimes PRAM can become corrupted or outdated, leading to various issues with your Mac’s performance. In these cases, resetting PRAM can help to resolve the problems and get your computer running smoothly again.
What are some common issues that can be resolved by resetting PRAM?
Resetting PRAM can help to resolve a variety of common issues with your Mac, including problems with the display, sound, and network connectivity. If you’re experiencing issues like a dim or distorted screen, no sound coming from the speakers, or difficulties connecting to Wi-Fi or Bluetooth devices, resetting PRAM may be able to help. Additionally, PRAM reset can also resolve issues with your Mac’s clock, including problems with the date, time, or time zone.
In some cases, resetting PRAM can also help to resolve more complex issues, such as problems with your Mac’s boot process or difficulties with certain applications or software. By resetting PRAM, you can reset the system settings and preferences to their default values, which can help to clear up conflicts and get your Mac running smoothly again.
How do I reset PRAM on my Mac?
To reset PRAM on your Mac, you’ll need to shut down your computer and locate the following keys on your keyboard: Command + Option + P + R. Press and hold these keys while you power on your Mac, and continue to hold them until you hear the boot chime for the second time. Release the keys and allow your Mac to boot up as usual.
Note that you may need to try this process a few times before it takes effect, as it can take a few attempts to reset PRAM successfully. Additionally, be sure to reset the System Management Controller (SMC) as well, as this can help to resolve related issues.
Is it safe to reset PRAM on my Mac?
Resetting PRAM is a safe process and will not erase any of your data or affect the installation of your operating system or applications. The only thing that will be reset is the system settings and preferences, which will be returned to their default values.
However, it’s always a good idea to create a backup of your important files and data before attempting any kind of troubleshooting or repair. This will ensure that your data is safe, even in the unlikely event that something goes wrong during the process.
Will resetting PRAM affect my user accounts or login information?
No, resetting PRAM will not affect your user accounts or login information. The only thing that will be reset is the system settings and preferences, which are stored separately from your user data.
You will still be able to log in to your Mac with your usual username and password, and all of your files and data will remain intact. The only difference you may notice is that some of your system settings or preferences may have been reset to their default values.
Can I reset PRAM on a Mac with a T2 chip?
Yes, you can reset PRAM on a Mac with a T2 chip. The process is the same as on older Mac models, and involves shutting down your Mac and pressing the Command + Option + P + R keys while powering on.
However, on Macs with a T2 chip, you may also need to reset the Secure Boot variables, which can help to resolve issues with booting up your Mac. To do this, press the Command + Option + P + R keys, then immediately press the power button to shut down your Mac. Press the power button again to turn it back on, and release the keys when you hear the boot chime for the second time.
How often should I reset PRAM on my Mac?
You should only need to reset PRAM on your Mac when you’re experiencing specific issues that are related to the system settings or preferences. This may include problems with the display, sound, or network connectivity, or issues with the clock or time zone.
In general, it’s not necessary to reset PRAM on a regular basis, as this can cause you to lose your custom system settings and preferences. Instead, only reset PRAM when you’re experiencing specific issues that are not resolved through other troubleshooting steps.
