If you have an Apple Silicon Mac with an M1 or newer processor, you don’t need to do anything special to reset the NVRAM. Resetting the NVRAM also resets those options to default.

Once you’re back in macOS, you’ll want to head to System Preferences and double check that your Display, Date & Time, and Startup Disk settings are what you want them to be. Keep holding these keys for at least 20 seconds after you see the Apple Logo, or until you hear the s econd startup sound for older models of Macs that still have that chime.Power on the laptop, and as soon as the power comes on, hold down Command + Option + P + R.Shut down your Mac (NOT via sleep using the power button).Disconnect all devices from the Thunderbolt and USB ports (except for your keyboard, if needed).If you have an Intel Mac, here’s how to reset the NVRAM: Many glitches and general Mac weirdness can result from something going wrong with the data in NVRAM, which is why resetting it is something you should try if your audio levels aren’t normal and nothing else you try works, This special type of memory (formerly known as PRAM) stores configuration information. Check whether your MacBook has any pending updates, and install the latest version of macOS that your Mac supports, such as Big Sur or Monterey.Īudio glitches can often be resolved by resetting Mac’s NVRAM (non-volatile RAM). Sometimes audio issues are the result of bugs or incompatibilities with newer software. These methods do exactly the same thing, so it’s up to you!

If you want to tweak the sound of any music you might be listening to, you’ll have to use that app’s EQ if it has one. The only problem is that macOS doesn’t come with an operating system-wide audio EQ. Using an EQ this way can also make the MacBook’s speaker usable at maximum volume with bass-heavy audio. For example, you can turn down low-frequency bass tones to improve clarity. An equalizer allows you to adjust the relative volume of different frequency bands in your audio.

In this case, using an equalizer (EQ) is the right solution. It may be that, rather than the volume being too low, you’re experiencing muddy or muffled sound, making it hard to follow dialogue or the finer detail in the music. Either switch to the correct audio output as described above, or unplug the device from the MacBook’s headphone jack. If you’ve plugged something into the MacBook’s headphone connector, it will automatically switch to the audio device you plug in. If you have Bluetooth headphones paired with your MacBook, disconnect them or switch to another audio output as described above.
