Start up chime

Yes... there is a way to get the startup chime back on your Mac. On newer ones it’s disabled by default. You can google that info. Also try doing a reset smc/ pmu and nvram reset as well

good luck

This is so frustrating. I keep losing the start-up chime which is supposed to signify that certain checks are being made at the start-up. It returned twice after updating, but now there are no updates. This is a brand new Mac; I haven't even made one payment on it yet. Not only does the chime fail, but the sound crackles. I ran diagnostics several times and the results were always negative. However, the diagnostic bar always only completes 1/3 of the way before popping out to tell me everything is okay. I can't risk going to the genius bar because of COVID. Any suggestions?

You do not state what exact Mac is this?

or

what exact macOS are you currently running?

Old issue, new issue, what changed?
