Using System Preferences: Access Sound settings to mute startup sound easily in System Preferences
Mac users often find the startup chime, affectionately known as the "dong" sound, either reassuring or annoyingly loud, depending on the context. Fortunately, disabling this sound is straightforward through System Preferences, a built-in macOS utility. By accessing the Sound settings, you can mute the startup chime in just a few clicks, ensuring a quieter boot-up experience. This method is ideal for those who prefer a silent startup, whether in a shared workspace, during late-night sessions, or simply for personal preference.
To begin, click on the Apple menu in the top-left corner of your screen and select System Preferences. From the grid of icons, choose Sound, which typically features a speaker symbol. In the Sound preferences window, navigate to the Sound Effects tab. Here, you’ll find a checkbox labeled “Play sound on startup.” Simply uncheck this box to disable the startup chime. For the changes to take effect, restart your Mac, and you’ll notice the absence of the familiar "dong" sound.
While this method is user-friendly, it’s important to note that the startup sound serves a purpose: it indicates that your Mac has successfully completed its hardware diagnostics during boot-up. Disabling it won’t affect your Mac’s performance, but you’ll lose this auditory confirmation. If you ever need to re-enable the sound, simply return to the Sound preferences and check the box again. This flexibility ensures you can adapt your settings based on your environment or preference.
For users running macOS versions prior to Big Sur, the process is slightly different. In older versions, the startup sound setting might be located under Startup Disk preferences, where you’ll find a checkbox to mute the sound. However, the System Preferences > Sound method remains the most consistent and widely applicable approach across macOS versions. Always ensure your system is updated to the latest version for the most streamlined experience.
In summary, disabling the Mac startup sound via System Preferences is a quick and effective solution. By unchecking a single box in the Sound settings, you gain control over your Mac’s auditory behavior at startup. This method is not only accessible but also reversible, allowing you to toggle the sound on or off as needed. Whether you’re seeking silence or simply prefer a quieter boot-up, this approach delivers results with minimal effort.

Terminal Command Method: Run a simple Terminal command to disable the startup chime
For those who prefer a hands-on approach, the Terminal command method offers a straightforward solution to silence your Mac's startup chime. This method involves accessing your Mac's underlying system settings through the Terminal application, a powerful tool that allows users to execute commands directly. By inputting a specific command, you can effectively toggle the startup sound on or off, catering to your preference without the need for third-party software.
Steps to Disable the Startup Chime:
- Open Terminal: Navigate to *Applications > Utilities > Terminal* or use Spotlight Search (Cmd + Space) to find and open it.
- Enter the Command: Type `sudo nvram StartupMute=%00` and press Enter. This command sets the startup mute option to disable the sound.
- Authenticate: You’ll be prompted to enter your administrator password. Type it in (note that the cursor won’t show any input for security reasons) and press Enter.
- Restart Your Mac: To test the change, restart your Mac. The startup chime should no longer play.
Cautions and Considerations:
While this method is effective, it’s important to exercise caution when using Terminal. Incorrect commands can alter system settings in unintended ways. Always double-check the command before executing it. Additionally, this method modifies a system-level setting stored in NVRAM, which persists across restarts but can be reset if you perform an SMC (System Management Controller) or NVRAM reset.
Re-enabling the Chime:
If you ever wish to restore the startup sound, simply repeat the process but use the command `sudo nvram StartupMute=%01`. This reverts the setting, allowing the chime to play again upon startup.
The Terminal command method is a quick and efficient way to disable your Mac’s startup chime, ideal for users comfortable with command-line interfaces. It offers a permanent solution without relying on external tools, though it requires careful execution to avoid unintended changes. For those seeking a reversible, system-level tweak, this method stands out as a practical and effective option.

Startup Key Shortcut: Hold Shift key during startup to mute the dong sound
Mac users often find the startup chime—affectionately called the "dong sound"—either reassuring or annoyingly loud, depending on the context. For those seeking a quick, temporary solution, holding the Shift key during startup is a widely effective method to mute this sound. This shortcut works across most macOS versions and requires no advanced settings or third-party tools. Simply press and hold the Shift key immediately after powering on your Mac, and release it once the login screen appears. The process is straightforward, making it ideal for shared spaces, late-night work sessions, or any situation where silence is golden.
While the Shift key method is convenient, it’s important to understand its mechanism. This shortcut disables the startup sound by temporarily overriding the system’s audio settings during boot. It’s a non-permanent fix, meaning the chime will return on the next restart unless you hold the key again. This makes it a practical choice for occasional use but less suitable for those seeking a permanent solution. For instance, if you frequently work in quiet environments, memorizing this shortcut can save you from fumbling with settings each time.
One notable advantage of this method is its accessibility. Unlike disabling the sound via Terminal commands or System Preferences, which require navigating menus or writing code, the Shift key shortcut is immediate and intuitive. It’s particularly useful for users who aren’t tech-savvy or prefer not to alter system defaults. However, it’s worth noting that this method doesn’t work on all Mac models, especially older ones. For example, some pre-2016 Macs may not respond to the Shift key shortcut due to hardware limitations.
To maximize the effectiveness of this shortcut, time your key press carefully. Start holding the Shift key as soon as you hear the startup chime or see the screen light up. Holding it too early or too late may result in the sound playing briefly before being muted. Additionally, ensure no external keyboards are connected, as this can sometimes interfere with the shortcut’s functionality. For MacBook users, closing the lid before restarting can help avoid accidental key releases during the boot process.
In conclusion, the Shift key shortcut is a simple yet powerful tool for muting the Mac startup sound on demand. Its ease of use and immediacy make it a go-to solution for many users, though its temporary nature may not suit everyone’s needs. By mastering this shortcut, you gain greater control over your Mac’s auditory behavior, ensuring it adapts to your environment seamlessly. Whether you’re in a library, a meeting, or simply prefer silence, this method offers a quick fix without the hassle of permanent modifications.

PRAM/NVRAM Reset: Reset PRAM/NVRAM to turn off the startup sound permanently
Mac users often find the startup chime either reassuring or annoyingly loud, depending on the context. If you’re in a quiet environment or prefer silence, disabling this sound permanently can be a priority. One effective method to achieve this is by resetting the PRAM (Parameter Random Access Memory) or NVRAM (Non-Volatile Random Access Memory), which stores system settings like volume, display resolution, and startup disk selection. This reset can turn off the startup sound without requiring third-party software or complex workarounds.
To perform a PRAM/NVRAM reset, follow these steps precisely. First, shut down your Mac completely. Press the power button, then immediately hold down the Option + Command + P + R keys. For Macs with Apple Silicon (M1 or later), hold these keys until the computer restarts and you hear the startup chime for the second time. For Intel-based Macs, hold the keys for approximately 20 seconds. This process clears the stored settings, including the startup sound preference, effectively disabling it. Note that this reset also reverts other system settings, such as screen resolution and time zone, so you’ll need to readjust them afterward.
While this method is straightforward, it’s essential to understand its limitations. A PRAM/NVRAM reset is not a universal solution for all Mac models or scenarios. For instance, some newer Macs with T2 security chips may not allow the startup sound to be disabled permanently via this method. Additionally, if your Mac is connected to a network with managed settings, the sound may revert after a system update. Always ensure your data is backed up before performing any system reset, though this process is generally safe and non-destructive.
The takeaway here is that a PRAM/NVRAM reset offers a quick, built-in solution to silence your Mac’s startup sound permanently, provided your system supports it. It’s a handy trick for those who value silence or need to operate their Mac discreetly. However, if the sound returns after updates or on newer models, exploring alternative methods like using Terminal commands or third-party apps might be necessary. For most users, though, this reset is a reliable first step to achieving a quieter startup experience.
