Apple Event: May 7th at 7 am PT
I've noticed in the last few days that the startup chime on my MacBook Pro has stopped working. I'm using OS Catalina 10.15.2. Everything turns on and off just fine; it's just that the startup chime has mysteriously stopped working. Anyone have a similar issue or know how to fix mine?
Thanks. Before I did this I saw that I had a new OS update waiting, so I upgraded my OS from 10.15.2 to 10.15.3 and now the startup chime is working again. Voila! Thank you for your help though. I'll keep it in mind if it should happen again.

Welcome!
What year is your MBP? Please see:
About Mac startup tones - Apple Support
including this bit:
Mac models from early 2016 and earlier make a chime sound when they start up. Mac models from late 2016 and newer don't have a startup chime, with the exception of MacBook Air (13-inch, 2017).
Which exact model is your MacBook Pro? Apple notebooks, since late-2016, no longer make a chime sound when starting up. The exception is the 13-in 2017 MacBook Air.

Does your notebook provide any sounds from its internal speaker, not just not providing the start up chime?
Ok, thanks for clarifying which MacBook Pro model you have. I am then assuming that the startup chime was working before ... correct? If so, then something may have disabled it.
You can re-enable it by using the following command in the Terminal app: sudo nvram -d SystemAudioVolume
Note: Using sudo will require that you know the Administrator password for your notebook.
I don't even know where to find the Terminal app, much less know what to do once I get there. And is my Administrator password the same as my password to turn on my computer? Sorry, I'm not very computer savvy.

You will find the Terminal app in the /Applications/Utilities folder. You would run it like any other app. When it runs it will open a window with a command prompt, similar to a DOS prompt ... if you are familiar with DOS. Regardless, you would just enter the command string I provided you, and then, press the return or enter key. Again, if it asks you for a password, you would use the same password you used when you first set up your notebook.
Finally, to close the Terminal window, enter exit at the prompt, and then, press return.
My MacBook Pro is a 15-inch with retinal display mid-2015.
Great! I'm glad you got things working again.
Why has my startup chime stopped working on my MacBook Pro?
