Connect the power cord again and wait for 5 seconds.Once your Mac shuts down, remove the power cord and wait for around 15 seconds.
Go to the Apple menu and power-off your system.If you own an Xserve, iMac, Mac Mini, Mac Pro, or any normal desktop version, then follow these steps: The steps to reset SMC would differ between various Mac models and versions. Before you do SMC reset, try to restart your Mac and make sure that all the other precautionary measures have been taken.
Though, chances are that there would be an issue with your Mac’s SMC and it needs to reset. It is related to more hardware functions while PRAM/NVRAM is associated with booting and other software-related components.įrom power buttons to battery management and keyboard to motion sensors, SMC is responsible for all kinds of things on Mac. It is not a part of RAM and is a dedicated chip on Intel-based Mac. SMC is pretty different than both PRAM and NVRAM. On the other hand, NVRAM is an SSD flash-based storage system that always retains the crucial Mac information. PRAM uses an inbuilt battery to keep it running and store the RAM component. While PRAM was mostly used in previous-generation models, NVRAM is a newer concept. Ideally, both PRAM and NVRAM on Mac have similar working with superficial differences. If an application is not loading, there is a problem with Mac’s booting or a clash in system settings, then you should clear NVRAM in it. Non Volatile RAM stores crucial details that affect the overall functioning of the system. That is why NVRAM consists of crucial information about booting, device configuration, and other permanent components. That is, it is retained even when the system is turned off. As the name suggests, the data stored in NVRAM is non-volatile in nature. NVRAM stands for Non Volatile Random Access Memory and is one of the most important components in a system. This includes any kind of problem with Mac’s trackpad, fan, power button, keyboard, and peripheral devices.

If there is a problem with your system’s physical component or internal communication, then you should reset SMC on MacBook Pro (or any other model). It is also linked with the Power button and puts Mac in sleep mode or restarts it by connecting it to the boot loader component. This includes major peripheral devices, keyboard, mouse, cooling fan, and even LED lights. Ideally, the chip is responsible for running various physical components of the computer. SMC (System Management Controller) is a dedicated chip that is used in Intel-based systems. Also, if your Mac is stuck in a boot loop, then you should consider resetting its PRAM as well. It is suggested to clear PRAM whenever there is an issue with the keyboard, volume, screen resolution, battery, and other system details. Ideally, the exact details stored in PRAM would differ from one Mac model to another. It stores vital system configuration and details like color settings, screen settings, date and time, volume configuration, and so on. PRAM stands for Parameter Random Access Memory that is a part of the primary memory in Mac. Let’s quickly learn what is PRAM, NVRAM, and SMC in Mac, to start things off. Basic Details for Mac’s SMC, PRAM, and NVRAMīefore we provide stepwise solutions to clear PRAM, NVRAM, and SMC, it is important to cover the basics.
