Cord unplugged from headphone jack causes Mac OSX to fail and shutdown.

I have a sound system running through my iMac. When I unplug the sound system, my iMac desktop turns gray & a message tells me that Mac OSX has quit. This has happened multiple times & I would like to know why.

Obviously, this should not happen. Mac OS X does make a software setting change when it senses the headphones mini-jack being removed. The System Preferences Sound pane Output tab setting gets changed to +built-in speakers+ and the speaker output volume is set to the previously set value for the +built-in speakers+ (which is stored separately from the headphones volume). It is not just a hardware speaker on/off switch like in most PCs.
So with that in mind, my first suggestion is to reset the PRAM.

No Sound From Headphone Jack, Only Internal Speakers working in Macbook Pro A1278

Hello, the internal speakers of Macbook Pro A1278 OSX 10.7.5 are working perfectly, but no sound from headphones or external speakers when plugged in. Headphones/speakers recognized when plugged in, shown by System Preferences/Sound, and since the sound stops from internal speakers when headphones/speakers are plugged in. No red light seen coming from headphone jack, as I read in other posts. The problem began after a cable was connected between computer and stereo system. Maybe overloaded the sound card and burned out a connection? Wondering if you think that the sound card needs to be replaced or is there another solution possible? Thank you.

Hello JohnBoarkman,
Welcome to the Apple Support Communities!
I understand that you hear no sound from your accessory when you connect to your headphone jack. My first troubleshooting suggestion for this situation would be resetting the NVRAM on your Mac. Please use the instructions in the attached article to complete this process and let me know if the issue continues.

Droid Razr Maxx- No output from headphone jack

I've got a Motorola Droid Razr Maxx phone which I'm very happy with. Only thing I just noticed is that when I plug in extrenal speakers or wired headphones, there is no ouput from the jack. Internal phone speaker is still on with wired device plugged in. Bluetooth works fine, but I've got an external speaker I'd like to use for music that isn't bluetooth capable. I've looked at the sound setting on the phone, but can't find anything for this issue. If anyone has an idea on how to fix this I'd appreciate it.

No as I said before in the post. I still dont believe I abused the first one, and I am not going to take the risk of having to pay 350.oo for the second one.
The only reason i took to the forums is to let others know of the service i received. First individual I talked to told be to go buy one from someone else.
The 2 hours I spent with your customer service reps both placed a request for a supervisor to call me. Its monday I have not heard from anyone.
Just have very little trust or patience with Verizon anymore.
And I haven't mentioned the ebill I received from Verizon for 429.00 for October that NO ONE at verizon can explain.
Just bad service, Period.

Yes, it's icloud's storage you will be expanding. All devices logged into an account will be able to use that storage.

Updating podcasts causes my iTunes to fail and close

When I update my podcasts, whether manually by using the refresh button or allowing the program to go update, it causes my iTunes to fail and close. I have tried multiple times, closing and restarting, killing it in Task Manager and restarting, rebooting the PC, and even uninstalled and reinstalled iTunes. I do get a generic "ITunes has encountered and issue and will close now. Windows will notify you if there is a solution" message, but that's it.

Audio from headphone jack stops working.

Hello.
When I play back audio on my MacBook pro in Traktor Pro, iTunes or even VLC it comes out my internal speakers like normal. If I plug my headphones in it will start coming out my headphones like it should and if I unplug them it comes back out my speakers again and it all seems to be ok. However if I close the lid and let the computer sleep, when I wake it up it will play audio out the speakers but if I plug my headphones in again they won't work and the sound will continue to come out of my internal speakers (while headphones are still plugged in). If I go into my audio settings it just says internal speakers and when I plug my headphones in it goes away and then the computer says it has no Audio device installed, if I goto adjust my volume with the key on the keyboard I get the speaker with the circle with the slash thought it if as to say volume cannot be done. The only way for me to get sound back from my headphones is to restart the computer. I don't know why it is doing it and have no idea what would be causing this. Is anyone able to help me out with this.? It's so frustrating having to restart my machine all the time as I am a DJ and run my DJ software and deck controllers from it. I have a mid 2011 17" MBP running Lion osx 10.7.2 (all software up to date as of 05-01-12) 8GB Ram.
Cheers :)

Sound coming from headphone jack becomes heavily distorted at the slightest movement of the headphone cable.

I use headphones almost exclusively of my Macbook Pro (Early 2011, way out of warranty) so this has really been annoying me. For about 1-2 weeks now whenever the wire from the headphones I have plugged in to the jack moves, even slightly, the sound coming from the left side disappears almost entirely while the sound from the right side becomes quiet and filled with static. Strangely, it doesn't appear to happen with everything that I'm doing on my computer. For example when playing games the sound seems to work just fine for the most part, but playing music or watching Netflix causes issues whenever the cord moves, which is really annoying.
To get it to stop, I have to move wiggle the plug around in the jack and slowly move the cord into a place where it will not be affected by movement very easily. I read that some people have been able to get around this by buying an external sound card and using the headphone jack on there, but I'd rather not do that if possible as there isn't really anywhere that I can put it without most likely picking up some interference. Plus I only have two USB ports, so I have to use a powered USB hub thats about 2-3 feet away from my computer for most things. Anyone know if this is a viable solution or how much it would cost to fix at the Apple Store?

Also, I have tried restarting my computer, messing with the audio settings, and various other settings that I thought might help.

Can't copy some files from Windows 7 to Mac OSX over network

Hi,
I'm running the latest version of Max OSX v10.8.4 on a brand new Macbook Pro.
I have followed the setup instructions at http://www.7tutorials.com/how-change-workgroup-mac-os-x-easy-networking to access my Macbook from Windows, and http://www.howtogeek.com/howto/24950/how-to-share-a-folder-in-os-x-with-windows/ to share some folders from my Macbook to Windows.
I am now trying to copy some files from my Windows 7 Pro (SP1) computer to my Mac, and have hit the following problems:
I can view my Macbook in my list of local networked computers on WIndows, but I cannot access it. Clicking on it causes Windows 7 to try and access it, but then I get a message after a minute saying the network path could not be found. However, if I manually enter the IP address of my Macbook in the Windows address bar (\\192.168.0.191), I can view and access all the shared folders. I can never access the Macbook via it's computer name (\\MACBOOK-ROB).
I cannot copy some files from Windows to my Macbook shared folders via Windows. There is nothing to distinguish these files from the hundereds of other files that I have successfully copied to my Macbook. They are pictures and music with no special characters in the filenames, not overly long filenames or folder paths, no access restrictions, or any other security restriction that I can see. However, every single attempt to copy these files to my Macbook results in WIndows reporting that access to the destination was denied.
I have tried both these above scenarios on WiFi and Ethernet, and the results are the same.
So:
Why am I unable to access my Macbook by it's computer name on the network? How can Windows see it, but not access it?
What are the limitations on transferring files over SMB that is (presumably) causing these specific files to fail?
Thanks for any help you can offer.

I have a fix for inability to copy files. I had the same problem moving a lot of old files across my LAN from a Windows XP machine to a Mac Mini running Mountain Lion. After confirming copy of some special file, I would get an error that terminated the copy operation, and info on the Mac side would show a locked folder.
I finally decided to eliminate all special files on the Windows side, before copying, by running
attrib -s -h -r /s /d [drive or folder]\*.*
in a command window. Running attrib /? tells what the arguments mean, but it doesn't explain that you need the *.* to make the command go through the hierarchy clearing the special attributes on all the files.
After I did that, and then used drag and drop between two Windows Explorer windows (one on the Windows drive, on on the target drive on the Mac), the whole move operation ran to completion without stopping either for error or to ask for confirmation.
I do not have a fix for the inability to access some computers by name rather than by IP address. I'm looking into the possibility of activating bind on the Mac but I haven't done anything yet.

Sound output levels from headphone jack

Has anyone else noticed that the output volume levels from the headphone / external jack are quite low? With my old iMac G5 (rev b) I could have the iMac's volume at 2 bars and it was plenty loud. Now I'm at 6 bars to get close to the same volume with my intel machine.
If I unplug my speakers, though, the volume from the iMac is quite high at this level, so it seems to me that there's a disparity with the output through the headphone jack.
Anyone else notice this?

I agree, and the sound from the onboard speakers is very low as well!
This is frustrating, my first iMac, the purple grape, from about 7yrs ago had kick-***, very good quality sound. Then, when I bought an eMac ,it was far less quality, (as I understood, due to far less cost), but I was bummed at the greatly reduced volume level as well. Also, I really liked the feature, where you set the master volume in preferences, but the desktop reading was relative to that, not the master.
However, now, after buying the top of the line ($$$) iMac, I have the same, if not LESS sound going on What is up with this, ESPECIALLY when Apple knows it's products are favs with we musicians, as well as the many music-lovers that don't play???
We don't appreciate having to set all levels at 10, just to get even a decent level, much less anything loud......very disappointing.

Inserting/removing headphone jack causes Application and/or Finder to crash

Whenever (and every time) I insert or remove any headphones from the headphone jack in my PowerBook, the current Application and sometimes the Finder immediately crashes. I'm not sure if this started after either the 10.4.2 or 10.4.3 updates, but I suspect that the updates are unrelated. Is this something others have experienced? Is it a hardward problem or a sound driver problem? I suspect that I need to send it in for repair -- but wanted to see if this is a know problem. Thanks.

Eric, welcome to the discussions, as you say, (Send it in)
Inserting or removing headphones should not cause these issues, and I haven't seen anything on this, It sounds like an issolated case...Cheers...Don

Left Audio Only From Headphones Jack With External Speakers

Yes, the balance is set properly under the sound system preferences.
So here's the problem, I have JBL Encounter speakers connected via the headphone jack and since yesterday only the left speaker produces sound.
I've plugged my ipod into the JBL speakers and they work fine. I've also used headphones with my computer and again, left audio only.
I've even switched the right and left satellite speakers and again only left audio is produced... though on the right (side) satellite.
Any thoughts on how to correct this? The nearest apple store is 2 and 1/2 hours away so I'd prefer not to go if there is another fix.
My three month phone service is up but I'm still covered under the apple care for a few more months.
Thanks in advance.

Sounds as if your headphone jack is either defective or has been damaged by having a cord yanked at some stage, Kanji
It is either a trip to your nearest AASP or a mailing box from Apple to get it resolved. Applecare will cover it if the problem isn't due to accidental damage (though a cat tripping on the cord can be enough to produce such results and the price could accordingly be substantial as the port is mounted on the logicboard on recent MBPs as I understand it) .
You might want to try a regular pair of headphones in the socket to make sure the problem also occurs with them, too, though.
Cheers

No sound from headphone jack on 2011 imac 27"

I usually use the headphone jack on the back of my iMac to drive studio speakers thru a mixing console. I recently unplugged the cable from that jack to hear something through the internal iMac speakers, which worked fine, and now that I've plugged the cable back in, I can't get the external speakers to work. In System Preferences/Sound/Output, the display vacillates between "Internal speakers" and "headphones" when I jiggle the cable in the headphone jack, which leads me to believe that the output jack has become damaged. That would mean taking it in for replacement, right? Or does Apple throw the baby away with the bathwater and just replace the whole computer, rather than replacing the jack itself?
In any event, does anyone have any ideas for me from what I just posted? Thanks very much.

Hi all again
After reading through a few other posts here I decided to check "System Preferences." After doing this I discovered that when the headphones are plugged in it set to mute. Not sure how that happened, as I nevered changed anything and I am only one using this computer. I guess it does not matter, as long as the problem is fixed.
Thanks
Michael

Red light from headphone jack--- no speaker volume

I am sure that I have done something wrong
but I no longer have any external sound or control of sound for that matter
and there is often a red light shooting from my headphone jack.
what must I do to regain control of my sounds.
thanks
1.67 g4 powerbook hi res Mac OS X (10.4.6)

The red light from your headphone jack is probably from the 'optical digital output'.
I don't know that model of PB but does enabling the digital out turn the headphone out off? Check in the sound control panel.
