I have been able to make the computer sleep by turning off the alert sounds. But that seems to be a band-aid. I am looking for a reason that this alert sound is happening. I have a wired apple keyboard and do not use bluetooth. Any ideas of where to look or what to look for?
Mac mini, OS X El Capitan (10.11.3), 2.3 GHz Intel Core i5
I have been able to make the computer sleep by turning off the alert sounds.
How did you do that?
Well, I thought that had worked. But now it isn't anymore. I had just turned off the volume of alerts off in system preferences and then put the computer to sleep and it slept for a moment then I woke it up. That is no longer doing the trick.
Please test after taking each of the following steps that you haven’t already tried:
Step 1
Take all the applicable steps suggested in this support article, including the ones under the heading "If the previous steps don't work." That's the starting point for any further effort to solve the problem.
Note that, as stated in the article, the computer will not sleep if some sharing services are enabled. From the menu bar, select
▹ System Preferences... ▹ Sharing
Turn off all sharing services.
Also note that the "external devices" referred to in the article could include Bluetooth devices, other than those made by Apple. If you're using a MacBook, MacBook Air, or MacBook Pro, or if you're using a desktop Mac with a wired keyboard and mouse, turn Bluetooth off to test.
Step 2
If iTunes Music Sharing or Home Sharing is enabled, disable it or quit iTunes. Do the same with any third-party applications that have a similar feature.
Step 3
Select
▹ System Preferences... ▹ Accessibility ▹ Speakable Items: Off
Step 4
Select
▹ System Preferences... ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
Open Bluetooth Setup Assistant at startup if...
Step 5
Step 6
Back up all data.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/var/vm
In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.
A folder named "vm" should open. Inside it, there may be a file named "sleepimage". Move that file, and only that one, to the Trash, but don't empty yet. You'll be prompted for your password. Close the folder window.
Restart the computer and empty the Trash.
Alert sounds will not stop, causing computer to wake up or not sleep at all
