Chime when MBP wakes from sleep

(David Brostoff) #1

Suddenly my 2017 MacBook Pro (10.14.2) makes a chime sound (three-note arpeggio) when it wakes from sleep.

I haven’t made any changes to notifications that I know of.

Any ideas?

Thank you,

About Mac startup tones

  • Three successive tones, then a five-second pause (repeating): RAM doesn’t pass a data integrity check. If you recently replaced or upgraded your computer’s RAM, check to see if it was installed properly. If the issue continues, contact Apple Support.

Thank you for the tip, although the sound only occurs on waking from sleep, not startup, and it doesn’t repeat.

Also, I have not replaced or upgraded the RAM in this computer. (This model is not user-upgradeable.)
