To reset the NVRAM of your Mac computer, first you will have to turn the machine off. Of course, this doesn’t always mean that if you have a problem with kernel panic instances, malfunctioning peripherals, or some other type of issue a NVRAM reset would fix that but it is still worth the try and can potentially save you lots of time of trying to complete more elaborate and time-demanding troubleshooting methods.Ĭommon instances when it may be a good idea to perform a NVRAM reset is if your Mac boots from a disk different from the one specified in the Startup Disk settings or if you are seeing a brief appearance of a question mark before your macOS loads. Because of this, many common problems encountered on Mac computers can sometimes be solved by simply resetting the NVRAM. What gets stored in the NVRAM depends upon what is that you are doing on your Mac at the given moment. Some examples of data stored in the NVRAM are the sound volume settings, data about peripheral devices connected to the computer, the display resolution, the current time zone, information about recent instances of kernel panic, etc. PRAM, which stands for parameter random-access memory, is also used for a similar purpose and the way to reset NVRAM and PRAM is basically the same. NVRAM stands for nonvolatile random-access memory and this is a type of memory that is used by your computer to temporarily store data which is needs to be accessed quickly which is why the amount of NVRAM that your Mac has directly corresponds to how quick the computer and how good its performance is.
