Loud beep when updating to 10.8.1?

Hi,
About half way of updating to 10.8.1 on my iMac it made about a 3/4 second BEEP

Not sure, but have you tried downloading the standalone updater from the Apple Support site, rather than doing it via the Software Update menu?

As regards slow boot, sometimes re-selecting the startup disk helps:
System Preferences>Startup Disk, select Macintosh HD, Mac OS X 10.8.x and click on restart.

Loud beep when restarting.

Earlier today, I was in class and everything was running a bit slow on my Macbook. So I shut it down and about an hour later when I was back home I turned it on and it made a loud Beep. Then whenever I restart it makes the optical drive little sound like when waking from sleep and then the sleep indicator light flashes really fast. Then it makes a loud beep sound and starts booting. Also has my indicator light on the power cord always been red?
Thanks

i have no idea what is happening but if there is a apple store nearby they can take a look at it.

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

Loud Beep when TM Drive plugged in

I usually plug in my Time Machine Drive every night and back up my computer. Last night when I went to do it, I plugged in the 500 GB USB drive and when I did, I got a loud beep out of my computer and the harddrives didn't show up on the computer. When I unplugged it, I got the same beep. I tried rebooting the computer and the drive with the same results. Any idea what's wrong and if it's the computer or the drive?

When you get the beep, check the system logs. Run console.app to access them.
If the drive is USB and powered from the computer, it may be that the transient is doing something to the 5v power on your computer.
The best way to do what you want is to leave the drive connected (when you resolve the issue) and simply turn TM on and off with the TM switch.
Also, after you boot, run the System Profiler and check the Diagnostics.

3 loud beeps when trying to start - won't start up

apple macbook wont start up and just give 3 loud beeps - then stops and does same again grey screen whilst trying

Hi Niel, my problem is a little different. I had an error message to restart while checking emails. When I tried to reboot, computer will not start and Beeps 3 times continuously. I reset the ram but it didn't make a difference. It is a fairly old 20" early 2009 iMac that I upgraded to snow leopard a few months ago. Is it time for a new one?

3 loud beeps when I try to start MacBook Pro

Backed up my MacBook pro running snow leopard. trashed a bunch of old files. everything was running fine.
I shut down and restarted.
It makes the tone but no apple icon. Then three loud beeps over and over. Sounds scary.
Never had this before. What does it mean? It sounds serious.
Thank you,,
Patrice

Hi Patrice,
That usually indicates a problem with RAM.
Try troubleshootingthe RAM. Shut down. Disconnect power adapter and remove battery. If the RAM youhave installed is not the RAM provided by Apple, remove that RAM and installthe Apple-supplied RAM. If you don't have the Apple-supplied RAM, or youalready have the Apple-supplied RAM installed, remove one module, try booting,move that module to the other slot, try booting, repeat with other module.
Ifneither RAM module works in either slot, then there are almost certainly otherhardware issues (usually the logic board, which covers a plethora ofpossibilities; unfortunately, the fix for almost any LB issue is to replace theentire LB), as the odds of both RAM modules and/or both slots being faulty areextremely low (but possible).

T500 loud beep when changing volume

My t500 beep loudly whenever I use my Windows XP to change the volume...even though I set the O/S sound scheme to "None"...It doesn't happen with the volume change button but I connect my laptop to an external monitor so I don't want to bother using the volume change button...
I'm trying to reinstall the sound driver to see if that's the problem?

Hi drixomanbets,
Maybe this will help:- http://www.howtogeek.com/howto/windows/turn-off-the-annoying-windows-xp-system-beeps/
In case above doesn't help, then enter BIOS -> Config -> Alarm ->Volume Beep -> Set it to Disabled.
Hope it helps

Loud beep after restart after Safari update

hi all everything is fine. But there was a loud beep when MCP had to restart after Safari update today. Should i be concerned? Like said everything is working fine. And this was the first time i heard such a beep. Its always been the regular chime instead.

Roger: That article applies only to iMacs.
True but I'm willing to bet the same (at least for the tone heard) applies to the MBP too. Let me see if I can find an advice letter that states that. In the link I suggested earlier there is a link that leads to:
http://support.apple.com/kb/HT1557
That advice letter does refer to MBP's so it's feasible the same advice is true for MBP's. At least that's my logic.

Macbook Air Loud Beeping!

Hi there,
I have become concerned lately, I have been finding that when I close my macbook air so that it goes on sleep, it will sound a fast and loud beep when it actually goes to sleep (not straight when the lid is closed). This is usually when it is plugged in.
However, sometimes when its not plugged in, and I may pick it up off a desk, or tilt it sideways to find the USB port, it will also make this loud beep. It's a little embarrassing in lectures!
Is there a problem with my hard drive or something? I have gone into utilities and used the disk utility to check my hard drive status, and it just says OK.
It never used to do this when I first bought this in Feb/March!
Any ideas?

Hi LeonJ,
A beep of any sort, outside of a POST chime on startup (which is more of a chime, than a beep) is not normal. There are diagnostic "beeps" built into the EFI firmware of Intel-based Apple computers used for diagnostics of component failure. Although typically the beep is on startup, not on sleep or shutdown.
Whereas Pappy's issue sounds more inline with when the beep should occur. Here are a few articles on some of the noise/LED-based diagnostics for the MacBook Air. But as iSMH previously identified, a service call might be the best solution. Even if it's a phone call into support for initial diagnosis.

Pavilion dv6 - loud beeping sound when starting +sound problem

i just bought an hp pavilion dv6 notebook LR732PA and every time i turn it on there's a loud beeping sound, and i'm not sure if this is normal but it asks me where to boot from (pc hard drive) and which oS (windows 7 64-bit). does anyone know how to stop the beeping?
Also sometimes the sound stops working altogether and an icon appears on the screen with a circle moving around it, and when i try to put the volume up the bar slides back down. it usually can be fixed by closing some programs and processes, it happens sometimes when ive just got 2 programs running and i close one and its ok, or if its not i have to restart. is this something to do with RAM or some kind of sound setting?
Thanks =)

There could possibly be a RAM issue here are a couple of troubleshooting links that might resolve your issue or give you an idea what the beeping is referring to.

Loud beep sound when starting up my Mac book air (2007), right before the classic start-up noise

There is a very loud beep right before the classic Mac start up "bong"
I'm thinking there might be something wrong with the ram...
Any answers? Thanks!

Although it's an older article, for the most part it's applicable -
http://support.apple.com/kb/HT2538
The beep on startup is usually an indication of a failed RAM module. It's also possible that a recent firmware update on the machine was botched. If you didn't recently perform a firmware update then it's probably the RAM. As the RAM is soldered directly to the logic board it cannot be replaced individually, it'd require a full logic board replacement.
Given the age of the machine, it's unlikely still covered by the AppleCare Protection Plan and definitely not the one year limited warranty.
The next course of action would be to bring the machine into the Genius Bar or AASP and have them evaulate your repair options.

When starting the computer I get the dong but then it stops with three loud beeps as the light in the front flashes in line with the beeps. The beeps repeat till switching off

HELP! W500 dead. Ran system update, restarted itself, makes 3 loud beeps and thats it!

I just changed my hard drive, stuck in a windows 7 cd, installed it successfully. Installed chrome, dropbox and system update. Ran Lenovo system update, and at some point the computer restarted itself, made three loud beeps (long followed by two short) and thats it.
The bluetooth light is on, as is the power on, battery, and charger lights. Screen is dead.
What happened? What are those three beeps? What do i do?
Solved!
Go to Solution.

Turns out my new hard drive is loose. Have to do something to make sure it doesn't move around.
That was a scary moment.
