    Intermittent "Cash Register" Bell Sound on Macbook Pro
    I am hearing an intermittent bell sound on my Mid-2010 Macbook Pro. It sounds like the cash register sound that Quicken makes when you enter a transaction. I just reloaded a new copy of Lion on a new HD, but still hear the sound. I ran a virus scan which claimed the computer is free of malware. Has anyone had this problem? I suspect its a hard to detect virus or software that is running in the background eating up resources.

    Specs:
    Mid-2012 MBP (16GB, 1TB HD), Monoprice 24-inch second monitor, iPhone 5s 32GB, iPad Air 2 64GB
    There aren't any viruses for the Mac.

    And there's no malware that makes a bell sound. Malware doesn't tend to want to call attention to itself.

    If it's a single bell, you're likely hearing the sound of incoming e-mail. This would be caused by you not actually quitting your e-mail program but just closing it instead (a common switcher mistake).

    You can hit command-tab to see what programs are actually open -- or just look down at the dock. The ones with "lights" underneath them are open.

    I appreciate the reply.

    Any computer can get a virus. While the MAC unix based OS kernel is more secure than the Windows OS, MACs can get viruses. In fact, Apple just released a patch this week to secure a vulnerable part of Java that made MAC users susceptible to the Flashback Trojan virus. Mac users have been lucky since nearly all the viruses are target toward Windows computers.

    Apple releases Java patch to thwart virus

    I do agree that Malware probably does not want to announce its there by a ringing bell. Mail and all programs are shut down and I stopped all processes possible in Activity Monitor. Still hear the bell. I am sure its a background process of some short running.

    After scanning the internet I only found an old post of a iMac G5 user with the same problem, but no one offered a solution. https://discussions.apple.com/thread...art=0&tstart=0

    While I appreciate the essay, I have been a Mac user for over a decade since the G4s. This problem is puzzling...

    Anyone else have any ideas? Its annoying.

    I hear a cash register when I play the only Facebook game I mess with called Cafe World but I am sure that is not your issue.

    You say this is a brand new install of OSX? Have you installed any applications on it and if so which ones?

    Unfortunately...too many. I loaded the new drive with a time machine backup from my prior main HD. I do video editing work and at times have downloaded free video converters. I am wondering if something I downloaded in the past few years is causing this issue.

    That was a question I forgot to ask you but you answered it anyway!

    Since you restored from a Time Machine backup you probably restored the sound! I wish I could help more but not sure what app is doing it. If you open Activity Monitor in Utilities, can you do a screen shot and show us what is running?

    Command+Shift+4 and select the area of the screen you want to capture then let go.

    It sure sounds like some background app is making noise alerts. Unfortunately, it could be any app since most nowadays seem to have some sort of auditory notification. I'd start by looking through AM as suggested by dtravis7 to see if anything looks odd (if you don't know, show us the list by saving it (File > Save). Make sure "All Processes" is selected first.

    No sir or ma'am you are incorrect. You are also confused about the Mac: the name is short for "Macintosh" it is not an acronym.


    In fact, Apple just released a patch this week to secure a vulnerable part of Java that made MAC users susceptible to the Flashback Trojan virus.
    This is precisely where you are incorrect. The Flashback trojan is a trojan. It is not a virus. Words mean things, and virus has a completely different definition than "trojan" or for that matter "malware." I suggest you educate yourself on the distinctions.

    Mac users have been lucky since nearly all the viruses are target toward Windows computers.
    Luck has had absolutely nothing to do it.


    I see the source of your misinformation and don't hold it against you. USA Today is in error calling it a virus. They are headline writers and bad journalists who didn't do their research or are just "shorthanding" inaccurately. It happens all the time but doesn't change the reality one whit.

    Still hear the bell. I am sure its a background process of some short running.
    Is it possible you have the clock set to chime the hour or some other interval?

    The journalists are just hoping for a Mac OS X virus ~ as there are none they just go ahead and fabricate. As stated probably came with the backup from TM.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I looked through your list and saw nothing obvious but might have missed something as some of your processes looked foreign to me.

    Is this sound exactly like a Cash Register that goes Cha-Ching?

    Also what Mac model you have and which version of OSX?

    Do you run any $$$ software named Moneydance by chance?

    Hi dtravis, thanks for trying to help.

    The sound is mora like a "Ching".. without "Cha".

    Mac Model: late 2009 iMac running 10.8.3 and never installed moneydance.

    This "Ching" sound is so annoying... ive tried to check on system log and nothing. Just cant find it.

    Sounds like it could very well be the default new message sound in Mail.

    Open Mail - Preferences - General tab - New message sound - change it to something else - then change it back to 'New Message Sound'. Is that the sound?
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    I understand this is a really old thread but I stumbled across it after Googling for answers after what sounds like the same problem has driven me to the edge. It's such an annoying sound!

    And luckily reading these posts inspired me to search and I found the answer:

    I have a Gmail extension installed on Safari called 'Gmail Counter'. I believe the whole point is that it shows a little badge notification when I receive an e-mail, but it has never worked that way and for me basically acts as a button to link me to my inbox. So I forgot it was even installed.
    Turns out it was THAT extension making the horrible 'bell' sound! Open up the extension settings and under the notifications menu is an 'Enable' checkbox I am now very happy to uncheck.
