iMac Bouncing Ball Sound

iMac running Sierra 10.12.6


I hear sound like a ball bouncing. It bounces 4 times...every 10 minutes...on the 4s - 12:04...then 12:14...12:24...and so on, non-stop.


Every time it is 4 distinct sounds, like a ball just bounced 4 times. Have tried Soundbunny, Console to track what application is causing it and haven't been able to.


Anyone else been having this problem and been able to solve it?


Thanks for your help.

1 - log into another user account on your Mac and see if the problem persists. If it doesn't then the culprit is something in your account. If it does then it's system wide.


2 - Boot into Safe Mode, Mac OS X: Starting up in Safe Mode, and check to see if the problem persists there. If it doesn't then it's caused by some 3rd party software and Safe Mode disables all 3rd party software.


3 - download and run Etrecheck. Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.
