Tones on Starting
Sometimes you'll turn your Mac on and it'll start beeping in a variety of patterns. Here’s a short list of what each beeping pattern means:
- 1 tone repeating every 5 seconds:
When you start your Mac, it will automatically run system diagnostics. If you hear this pattern of beeping, it means that the Mac could not find any RAM installed. Either your computer's memory was removed or something is interfering with the system checkup.
- Checked with Apple KB - About Mac startup tones and this pattern is not listed as an official form of communication. Rebooted a number of times and the same exact pattern occurs. Used a timer to verify it is definitely 3 seconds in between the 3 beeps. Booted into Apple Hardware Test and no problems found after running extended tests.
- Jan 30, 2019 The Sleep Indicator Light (SIL) on your MacBook, MacBook Air, and MacBook Pro has different behaviors based on the state of your Mac. These behaviors also occur on some iMac, Mac mini, and Mac Pro models, though not all Macs have a SIL. If the SIL flashes one or more times after you turn on the computer, and the pattern repeats after a.
- 3 successive tones followed by a 5-second pause:
This indicates that the Mac found RAM installed, but the memory failed to pass the data integrity check.
- 1 long tone if you hold down the power button:
My MacBook Pro began to shutoff randomly and would proceed to beep 3 times before restarting. After conducting some research, I found that this was likely caused by the RAM and a quick re-install (pop-out the stick and put it back in) would do the trick. However, it had gotten to the point where my MacBook would go into this 3-beep RAM-failure.
This indicates that an EFI ROM update is in progress. This only happens on computers manufactured before 2012.
- A successive sequence of 3 long tones, 3 short tones, 3 long tones, etc.:
This means that your computer has detected an EFI ROM corruption and the computer is in EFI ROM recovery mode. Newer models recover automatically from a corrupted ROM. When this occurs, a progress bar appears on the screen during ROM recovery mode. While on this mode, you should not shut down or disturb the computer in any way until it completes the OS X boot.
For all of the tones on boot up we discuss above, you should look into contacting Apple tech support since they all indicate you’re your computer could be in dire need of maintenance.
User-Induced Tones
You can also cause your Mac to produce tones, usually with certain key combinations. These key combinations will initiate some operation upon start-up. These are a few of those combinations:
Macbook Air Beeps 3 Times
- Shift ⇧
Start up in safe mode.
- Option ⌥
Launch Startup Manager.
- C
Start up from a bootable CD, DVD, or USB drives.
- D
Start to either Apple Hardware Test or Apple Diagnostics, depending on which Mac you’re using.
- Option-D
Same above, but it will start these programs via the internet.
- N
Start up from a compatible NetBoot server.
- Option-N
Start up from a NetBoot server using the default boot image.
- Command-R
Start up from OS X Recovery.
- Command-Option-R
Same as above, but using the internet.
These are some of the commands available at the start up and they will also produce unique sounds too.
It’s always important to know how to differentiate between user induced sounds and system sounds, as they can indicate a hardware or software failure on your Mac.

MacBook Pro :: I7 - 3 Beeps On Startup?
Mar 12, 2012
My Macbook Pro battery had run down (it does quite a bit) so I rebooted with the power inserted.
I get a frozen screen saver which is normal, while the progress bar finds it feet back on power.
However this time, I had the frozen screen saver, and a continuous 3 beeps which I've never had before in a loop? I then re-pressed the power switch on the Macbook and it rebooted fine and seems ok.
This i7 is coming up to its first year (which I think is covered by Apple?) and I *think* this maybe a memory issue? If it is, and my Mac is covered, then by a sheer stroke of luck, I decided to get Apple to fit the 8GB memory at the time of purchase (bad I know! and I don't usually do that) BUT that would mean that Apple fitted the memory upgrade and I haven't touched anything myself.
I then booted up this morning with a full battery and the boot up took a lot longer than normal - maybe around 3 minutes on the spinning logo, and then finally booted - are these all worrying signs?

MacBook Pro :: Three Beeps On Startup Even After RAM Replaced?
Feb 27, 2012
I'm working on a Macbook pro 15 A1278 for a friend. They were given the computer by someone who didn't want it. My friend did not have the password to get into the machine and no original system disc. I thought this was going to be an easy case of erase-and-install. So I attempted to boot from my own Snow Leopard DVD, then I started getting three beep errors. Now I can't get as far as the password screen any more. Computer starts with normal chimes, then when it gets to the grey screen with the Apple, I get the 'three beeps'. Bought new ram, put it in, reseated it a bunch of times, still three beeps every time.Attempting to restart using the system DVD by holding the C key, same problem. DVD spins up but then three beeps. Fired the machine up as a target disk and ran disk utility via remote control from another machine, we'll call that one 'machine B'. Hard drive checks out with no errors and is formatted in Extended Journaled. Did a clean system install from machine B (while still in target disk mode). System install was a success and was able to restart machine B successfully from the hard drive of the faulty machine.

MacBook Air :: 3 Beeps Continuously On Restart?
Mar 9, 2012
This morning, when I got into work I restarted my Late-2010 MacBook Air (128 GB HD, 1.86 GHZ Core-2 Duo, OS X 10.7.3) while holding down the 'option' button as I normally do to access bootcamp and load Windows 7 because I need to use Excel Macros during the work day. What was unusual, however, was that it immediately started beeping loudly when I held down the option button and continued to do so without ceasing. It beeped 3 times, stopped, beeped 3 times, stopped etc.
The fans started running pretty quickly and I held down the power button and it finally shut down. I restarted and held down the 'option' key again, booted into Windows 7 fine, and have since rebooted into OS X as well without issue. It's the first time that I've heard this beeping except when I installed a firmware update a few weeks back. I've done a bit of research and it sounds like it's indicative of a RAM issue but want to see if anyone knows for sure. I think it's strange that it did it once but hasn't again despite numerous restarts and also strange that it happened immediately upon hitting the 'option' key when the screen went dark, as I always do.

MacBook Pro :: Freezes On Start Up And Beeps
Jun 2, 2012
I have a brand new Macbook Pro (Christmas 2011), and today it was installing updates. It stated that it needed to restart to complete the updates, so I confirmed it. It shut down fine, but then didn't start up again on it's own. I waited for about an hour before manually starting the computer by pressing the power button. It did the opening chime and then the logo screen came up, but then it started a series of beeps along with blinking battery light (it is fully charged). It froze on the logo screen and continued to beep for a half an hour before I forced it to shut down (control+command+power button).
I tried restarting it in safe mode (holding the shift button down during startup), but it only resulted in the computer freezing on the logo screen for about five minutes before shutting itself off (no beeping or light that time, though). I went through my instruction manual as well as online searches to see if maybe I could somehow restore the computer to factory settings. I can get it to get into the Disk Utility section (holding down the option button during startup), but I'm absolutely terrified of erasing something I shouldn't.

It's the first time that I've heard this beeping except when I installed a firmware update a few weeks back. I've done a bit of research and it sounds like it's indicative of a RAM issue but want to see if anyone knows for sure. I think it's strange that it did it once but hasn't again despite numerous restarts and also strange that it happened immediately upon hitting the 'option' key when the screen went dark, as I always do.

Macbook Pro Beeps 3 Times Will Not Boot
MacBook Pro :: It Makes Random Beeps?
Mar 19, 2012
I bought a new MacBook Pro a few days ago, and it randomly makes this beeping sound. It's not like a problem noise and it comes from speakers. A bit something like a Skype sound, but it's not Skype..

MacBook Pro :: It Gives 3 Beeps Of Death When Waking Up Only
Mar 30, 2012
My new to me macbook (2010 MBP with 2.53 i5 running lion) runs great other than if I let it go to sleep for more than 5 mins it will give me the 3 repeating beeps until I hold down the power button and force a shut down. It never does this when turning it on from shutting it down, just waking up. I also checked the ram and made sure it was seated correctly.

MacBook Pro :: Freezes On Start Up And Beeps
Jun 2, 2012
I have a brand new Macbook Pro (Christmas 2011), and today it was installing updates. It stated that it needed to restart to complete the updates, so I confirmed it. It shut down fine, but then didn't start up again on it's own. I waited for about an hour before manually starting the computer by pressing the power button. It did the opening chime and then the logo screen came up, but then it started a series of beeps along with blinking battery light (it is fully charged). It froze on the logo screen and continued to beep for a half an hour before I forced it to shut down (control+command+power button).
I tried restarting it in safe mode (holding the shift button down during startup), but it only resulted in the computer freezing on the logo screen for about five minutes before shutting itself off (no beeping or light that time, though). I went through my instruction manual as well as online searches to see if maybe I could somehow restore the computer to factory settings. I can get it to get into the Disk Utility section (holding down the option button during startup), but I'm absolutely terrified of erasing something I shouldn't.

MacBook Pro :: Beeps When Turning Volume Up - Down / Solve This?
Sep 29, 2010
I have used a Macbook Pro from 2007 and have now recently bought the all new 17 inch Macbook Pro.
Something that really annoys me (and my ears) in the new MBP is the crystal clear sound of the Macbook pro speakers when i hit the Volume up or down key on my keyboard. The sound is just too treble and so loud and it gets even worse when i put headphones on and turn down the volume its even more deafening.
Anyone think the same?
Is there a way to solve this problem?
MacBook Air :: Headphone - Loud Hiss - Odd Beeps
Feb 23, 2008
Is anyone else having problems using their headphones with the Macbook Air? My Shure E500 headphones have a loud hiss and instead of playing music properly, the music is filled with odd bleeps and bloops. I have a similar problem with my Etymotic headhones. I *think* the standard iPod headphones worked fine, but I no longer have them on hand to test.

my Macbook Pro doesn't boot after updating the EFI, I just updated and restarted as it says in the description of the update and then it does not boot, making 4 short beeps and then 4 longer, I don't know what's happening. There was no problem during the update (no problem with electricity or similar)
