The Parameter RAM, or PRAM, on your Mac is a small amount of non-volatile memory (ie, persistent memory that is not cleared when the power is off) that is used by the system to hold hardware configuration settings such as the audio volume at startup, the default boot disk, and various boot arguments to pass to the default operating system.

Mac notebook computers that have a nonremovable battery include MacBook Pro (Early 2009) and later, all models of MacBook Air, MacBook (Late 2009), and MacBook (Retina, 12-inch, Early 2015).

is a subsystem of Intel processor-based Macintosh computers.

The SMC has roles in controlling thermal and power consumption, battery charging, video mode switching, sleep and wake, hibernation, and LED indicators.

It also enables enforcement of the Mac OS X End User License, allowing it to identify when it is running on non-Apple hardware.

Corrupted SMC firmware, whatever the cause, is not entirely uncommon and may lead to operational problems. Resetting the SMC may resolve certain issues, like,

  1. Cooling fans running in high speed
  2. System running very slowly compare to it’s specification
  3. Failure to recognize keyboard, trackpad or other external usb devices.
  4. Failure to wake from sleep, or unexpected sleep
  5. power loss suddenly
  6. power button not working completely
  7. battery performance reduced
  8. Non-function of LED indicators

Resetting the SMC is usually accomplished by removing all power from the system for a period of time (by unplugging the mains connector or removing the battery) or .

Apple provides model-specific instructions for SMC reset

“parameter random-access memory” or PRAM, stores certain settings in a location that OS X can access quickly.it keeps information about Mac so that it functions to it’s specifications. Old Macs used to have a “PRAM battery” which was a 3.6V 1/2 AA battery on the logicboard (motherboard). Newer Macs made since 2006 are Intel-based and use an ordinary CMOS battery that is a lithium CR2032 battery.

The PRAM stores the following information:

•Volume for both system startup and speaker
•Time zone information
•Mouse and trackpad scaling and speed information (commonly called mouse acceleration)
•Keyboard repeat rate
•Kernel Panic information
•DVD region settings
•Default system fonts
•Startup disk
•Disk caches
•RAM disks
•Virtual Memory (commonly called swap)
•32-bit addressing
•Video and display information including monitor depth, refresh rate, screen resolution, and number of colors

The type of information stored in the PRAM means that if you reset it, you’ll need to specify particular settings afterwards, like your mouse tracking speed and time zone (if you don’t use an Internet time zone server).

When do you need to reset PRAM?

You generally only need to reset PRAM when you’re being affected by the above contents stored in the PRAM. It is often recommended as a preliminary check before trying other things when troubleshooting a Mac. If you’re having problems with your Mac, it is worth a try

Resetting the PRAM is different to resetting the SMC.

Resetting the PRAM

You can reset the PRAM by restarting your Mac and holding down the keyboard combination Command+Option+P+R. (Not Power Key) These keys need holding down simultaneously immediately after you restart your Mac, while its starting. While holding the keys, you will hear the Mac boot chime again, this is your Mac telling you the reset has been successful. You can now let go of the keys – the reset is complete, your Mac should now start up normally. The keyboard combination will only work if you hold the keys down before the grey screen appears. If it doesn’t work, restart and try it again.

this trick used to be called ‘Zapping’ the PRAM in earlier days.

Apple provides a support article about resetting the PRAM.

Part 1. What are PRAM and SMC?

These are jargons for laymen but the PRAM and SMC are integral parts of Mac. They divide both the soft and hard aspects of the system for a smoother workflow.

We’ll discuss and define each to get a clearer view.

What is PRAM

PRAM or also called Parameter Random Access Memory is the one who stores most of the display settings on Mac such as the desktop, time and date, speakers, mouse, other control settings, and more.

PRAM is powered by a small internal battery which is the main reason why these configurations don’t get lost when the device is powered off.

There are instances wherein the PRAM gets corrupted but a reset can easily fix the problem.

What is SMC

SMC or also known as System Management Controller is the one who handles most of Mac’s physical performance such as the fan, ports, LED indicators, Bluetooth, power, lights, and more.

Manual pram reset mac pro 2009 model

It manages more parts than the PRAM.

SMC’s are available to Intel-based Macs and can also be fixed easily when things start to act weird or not responding to any configurations at all.

Both parts are vital in Mac performance and one needs to work with the other at all times based on what kind of Mac system used.

However, in more updated Mac models, instead of PRAM, they use NVRAM or called Non-Volatile RAM which acts the same but file corruptions are lesser as compared to the former.

When things go out of hand on PRAM and SMC, a simple power reset cannot fix any issues. You need to reset Mac PRAM and SMC in order to resolve any troubles.

Find out how you can reset them in the next parts below.

Part 2. When to Reset Mac PRAM and SMC

Resetting the PRAM and SMC should not be done out of habit. You should only do this when your Mac shows symptoms and appears to have the PRAM involved.

PRAM contains the following:

Virtual memory

Disk cache

RAM disk

Startup disk

32-bit addressing

Speaker volume

Keyboard

Application fonts

Status of messages

Serial port configurations

And more…

You might even see an error screen if the PRAM is not functioning well. If you are not too familiar with how these settings above work or how to fix them, better do the research first to avoid unwanted scenarios.

We will guide you on how to carefully reset Mac PRAM and SMC in a user-friendly manner as possible.

How to Reset Mac PRAM

Power off Mac. Turn it completely off and not just letting it sleep

Be quick and gentle to press and hold the Power button + Command +Option + P+ R. Press these keys before the screen goes gray or else you have to repeat the steps.

Continue holding these keys until the Mac restarts and you hear the startup sound

Release the keys and let Mac do the reboot normally

If you did not hear the startup sound twice, then probably have not reset the PRAM and might need to repeat the steps above.

However, if your PRAM does not nor is not saving your customized setting anymore, think about replacing the PRAM battery.
