Loud beeps NOT during startup...

In the past few weeks I have experienced 3-4 times where my computer would suddenly lock up and repeatedly emit a series of three LOUD beeps. I need to hold down the power button in order to shut the computer off. After restart, Safari seems to hang. If I close a couple tabs, the problem disappears. In looking at the logs, it appears it may be related to "WebProcess"? Has anybody else experienced this, know possible reasons or solutions?
27" 2010 iMac with 12GB RAM running OSX Lion

I experienced the same issue: my 21" iMac 3.6 GHz i5 with 8GB RAM and Mac OS X 10.7.1 freezes (only when I'm using Adobe Flash, either CS3 or CS5) and emits a sequence of three loud beeps, repeatedly. The cursor does not move on the screen, and the iMac must be forced to power down and restart. Here is a sound recording of the beeps:
http://macboy.com/mac-three-beeps.mp3
I ran the disk diagonstic tool that came on the Installation DVD, but it did not turn up any memory issues or logic board problems, even in extended diagnosis mode.
The freeze problem has been happening occasionally, but usually without the beeps. Instead it had been a cacaphony of random loud digital crunchy bit sounds.

Very loud beep (not at startup)

I was working on my iMac today, and all of a sudden, it made a loud beep. This was so loud everyone in the room nearly jumped out of their skin. This is not like the tone you hear when making a firmware update, it's something completely different. It was more of a buzzing sound than a clear tone, and it happened after the machine had been on a few hours. Everything seems to be fine, but I really want to know what that was all about. Has anyone encountered this?

Thanks. I can see where I rebooted, which I assume is where it says "Shutdown NOW!" (sounds a little too urgent for a voluntary shutdown). Some stuff happened with Google Chrome and Photoshop (weird, since I was using InDesign at the time). A quick Google search reveals that exit code 1 is generic and doesn't really tell you anything. I don't know what "headlights" is. So it seems like it could be Chrome or something Adobe, but I'm not sure what to make of this so it's not all that helpful.

Imac emits 2 quiet beeps NOT at Startup

So my Imac is running just fine as normal but every now and again it emits a quiet 'beep-beep.'
Have checked the console and nothing's showing up around the time of the beeps so I really haven't a clue what it is.
Any ideas?
Regards,
Mike

The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
 2 beeps = incompatible RAM types 
3 beeps = no good banks 
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
 5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.

Mac Mini Erratic Beeping NOT On Startup

Over the past couple weeks my Mac Mini has ominously beeped on 4 occassions. The first and second times it was one short beep. The third time it was three short beeps. And today it went kind of nuts; the beeping was irregular, patternless, and didn't stop on its own. On every single occasion I've had my ministack external HD on and iTunes running (music library is on the HD). When today's irregular beepfest occurred, I quickly quit iTunes and the beeping stopped immediately. I have noticed that my system lags somewhat when I run iTunes, and the last two occurrences of beeping have happened when the system seemed particularly busy (fans were going full blast). I've read that beeping commonly indicates RAM problems, but I've had no issues upon startup, and as soon as the beeping stops everything seems normal, with no obvious RAM-related symptoms.
Thanks in advance for any help!
-David

Mac minis beeping is only an indicator or a RAM issue if it happens at startup and is a recognizable pattern of one, two or three beeps separated by a brief silence. If you don't get that indication, it means that your system RAM is OK. If it were not, for instance if there were problems due to a memory stick overheating, you would see system crashes, and likely kernel panics.
I wonder if the beeping you hear is associated with the system alert sound - the sound the system makes to identify an error or problem, in which case what you are more likely to be suffering is a software or MacOS issue.
Next time this happens, note the time (shown in the menu bar) and try looking in the Console (in Applications>Utilities) to see if there are any log entries which match the time. If so, those log entries are likely to provide some guidance as to what is going on.

MacBook beeps once during startup, then loads up normally.

I have had this problem for about five days already. My Macbook 5.1 (late 2008) boots up and makes one 3 second long beep sound, then it starts up normally after. It is very annoying, as I use it in uni and other public places, and it makes this sound. I have tried changing my ram to the old one 2 x 1gb, and back to 2 x 2gb, it didn't help. I have searched all websites for this answer, but didn't get any answers to this problem
Please help, as I am doing alot of work on it now, and if there is a problem with it, I really need to know it.

Yeah, that time they gave me a replacement MacBook Pro 13 inch, very good service. Now I have trouble with my new retina macbook pro, there are dead pixels on the screen.

Three loud beeps on startup

I have been experiencing three loud beeps on startup with my Macbook Pro.
Aftter the beeps, the computer stays on a blank screen until I force a shutdown and restart, sometimes taking 3 tries to get past the beeps. Otherwise, It runs great, never crashes or locks up.
I tried reseating the RAM (2-1 gig dimms) after someone told me they thought that the distinctive 3-beep warning was a "bad ram" message. That did not make a difference.
Does anyone know what this may mean?
Thanks,
Dave Kowalski

2nd that - first check the ram is firmly seated - sometimes it's not all the way in the slots..
Take a look here;

Best of luck.

3 times loud beeping sound after press on button but never startup (mac min

Three beeps at startup indicate 'no good banks', meaning the system can't access the RAM.
It may be that your RAM itself is bad, or that it has come unseated. It could also indicate a more serious motherboard fault which prevents the RAM being accessed, but that is unlikely.
If you have opened the mini in the past it may be that the best way to check is to do so again and ensure the RAM is properly seated by removing it and reinserting. If you replaced the original RAM and still have the original stick, try putting that back in. Also note that Macs are typically very sensitive to RAM incompatibilities, and there have been cases where systems fail as yours appears to have done for no reason other than that a RAM stick was marginal in compatibility.
If you upgraded the RAM yourself and bought the replacement stick from a source such as Crucial.com which permits unconditional exchanges, contact them and arrange to have the memory replaced.

Frequent system freezing. Restart computer message, followed by beeps during startup

For the past few weeks I've been having repeated crashes on my MBpro 4.1, with OSX 10.6.8, fully updated. The system randomly freezes and I have to force a restart. Sometimes the system does not restart but gives a series of beeps remaing on black screen. If I let it rest a while it then starts properly.
I did a complete reformat and fresh install with only the basic software I need but the problem has not been resolved.
I have already tried changing the memory modules, without solving the problem.
Any kind advice would be greatly appreciated! Thanks.

CS3 Extension that initializes a JS-Object during startup is not working in CS4

Here is a simple Extension that works fine in DW CS3 and doesn't work in DW CS4 (trial version):
The File myObj_Startup.htm was placed in Folder Configuration/Startup. It initializes a quite simple Javascript-Object during Startup of DW.
Content of myObj_Startup.html:

<HTML>
<HEAD>
<TITLE>beim Öffnen</TITLE>
<SCRIPT LANGUAGE="javascript">
myObj =
     showMsg : function (msg)
         alert(msg);
function onOpen()
   myObj.showMsg("startup");
// SCRIPT ENDE
</SCRIPT>
</HEAD>
<BODY onLoad="onOpen();">
</BODY>
</HTML>
Besides this, an additional menuitem was defined in menus.xml to use the JS-object myObj:
<menu mmstring:name="menus/DWMenu_File" id="DWMenu_File">
        <menuitem name="Test" command="myObj.showMsg('Testing');" enabled="true" domRequired="false" id="DWMenu_File_SIEMENSTEST" />
        <menuitem mmstring:name="menus/DWMenu_File_New" key="Cmd+N" command="dw.newDocument()" enabled="true" domRequired="false" id="DWMenu_File_New" />
With Dreamweaver CS3 everything works out fine: I get a Alert-message: "startup" during Startup and when I'm clicking Menu->File->Test I get a Alert-message: "Testing".
With Dreamweaver CS4 (trial version) I get a message: "startup" as well but when I'm clicking Menu->File->Test I get no message.
Instead I get a Logfile "C:\Documents and Settings\user\Application Data\Adobe\Dreamweaver CS4\en_US\Configuration\Logs\DW JavaScript.log" telling me:
   JS Error:
       myObj is not defined
       filename:
       lineno: 0
       While executing DWMenu_File_TEST command in menus.xml, the following JavaScript error(s) occurred:
       ReferenceError: myObj is not defined
Why is this simple extension working in DW CS3 and not working in DW CS4?
Did they change the treatment of JS-objects initialized during startup?
Is the object out of scope?
Are such extensions not working in trial versions of DW CS4?
I cannot explain this behavior - please help!

Hi,
I have an similar problem and couldnt find an workaround for the problem.
When i add an new menu item to the menus.xml file, the menu item shows up, but my custom command (simple alert) wont trigger.
Can somebody please help?

Not restarting; loud beeping when attempting to restart

I was running a DVD on my macbook when it froze. after doing everything I could to restart it (force quit, trying to eject the disc, etc.), I shut down my computer to restart it. Now every time I try to turn it on, it goes to the gray screen (without the apple sign), and makes a loud beeping noise I've never heard a Mac make, only PCs. It beeps three times, then pauses, then repeats. It does this if I'm running on battery or if it's plugged into the power adapter.
Is there some way I can eject the disc? Would this help? Or is this beyond my (poor) computer skills and do I need to take it in to the experts?

See Power On Self-Test Beep Definition - Part 2. You may want to run the diagnostics:
How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error

Low Beeping Mac--NOT at startup

I have a MacBook Pro, bought it back in 2010.
I've been travelling a lot in the last month, but have never dropped my computer or left it out of sight. I installed Java a few days ago while in China and am now in Malaysia. While I did notice the trackpad not working as well, nothing seemed wrong with my laptop.
Yesterday, it started to make low beeps, somewhat like a piano key being played. It occurred sporadically, sometimes playing 3 beeps in a row, pausing, then playing two more. Or a single beep would play, while other times about six beeps would go off.
The noise can be adjusted with my volume. I've shut down every app and still the beeps continued. I've turned off my laptop twice (no beeping occurred at startup), but they still continue to play today. I've run diagnostic tests and have never installed new RAM. The disk is not full and still has almost 100GB free.
Can anyone help?

Three beeps at startup means you have either bad RAM or bad memory slots. Reseat RAM or change RAM module could solve the problem.
Before that, you'd better run Hardware Test to consider which or both RAM module is/are bad.

Aluminium keyboard sending repeat keystrokes/not recognised during startup

hi everyone, my first post here,
i recent purchased an additional slimline alu-keyboard for my imac to customise as an editing keyboard for logic pro. only problem is i appear to be having issues with it. recently it has been sending repeat keystrokes in os x. it's not one of the letter keys because no text is typed onscreen. the other issue is that during startup none of the boot-up keys are recognised (ie. reset pram combination/bootup menu) with leads me to belive something is very wrong.
i have already tried reseting the pram - although i had to use my other keyboard to do this as the new one isn't recognised. i also tried reseting the smc but it seems certain that there is an issue with the keyboard itself
the keyboard is still well within warranty and i have my receipt but i'm concerned about the fact that it has been customised with a editing layout set and might not be replaced
hope someone can suggest something!
thanks
j

ps. i just did a little further googling and it seems to be suggest that this is a 10.5.6 usb related issue

Freeze during startup if magic trackpad not available

Down in SF last week and bought a magic trackpad and installed it. worked fine.
Got home and turned on my MBP; it froze during startup with only the finder window open, no dock, and not much else. mouse pointer couldn't click on things, etc. I tried restarting and restarting into my test (bare bones) account. No luck.
Then I wondered if the problem was that my new magic trackpad was there and turned on. That was the problem. As soon as I got the trackpad and turned it on, my system completed normal startup.
Anyone else have this experience. This seems like a bug.

Today I tried to replicate my problem and couldn't. Either by turning off the trackpad before I shut down or else while my computer was off.
So apparently my incident was an isolated one.

IMac makes a loud beep on start up, won't load past the blue screen and the black ticking dial appears every few seconds in centre of screen.

Urgent help!
Out of the blue my mac lost the mouse cursor even though it had connection so I rebooted only for the mac to make a loud beep on start up then get stuck at the blue loading screen. It won't load past the blue screen. I've tried to reboot holding down the shift key but no change. I've also shut down, unplugged the main for 15 seconds, re plug and wait 5 seconds before starting up again but no change. Does anyone have any suggestions?
PS: I'm not too sure which systems I am running without being able to check in about this mac. I bought my imac in January or February 2011 if that helps.

The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
