• Is this normal for retina imac to do great headphone plug sound during installation first speakers?  Some new arise as well.

  I have an imac of retina.  Since the day I bought it new, I also had new harman/kardon talking plugged into the headphone jack.  This has worked well for more than a year or two.  Recently, I noticed an occasional static or pop.  It is not very strong, it's just boring.  I went to make sure that the headphone jack was still firmly inserted on the speakers and a very strong buzz takes place when you first insert the speakers.  To be fair, makes the noise even if I touch just the end of the shooting (of speakers), as if my human energy is impacting on the speakers.   Is this normal?

  Everything seems to work very well for most Park with the imac and the speakers, once I insert them.  But they are a very strong when buzz jack of first contact with the helmet of the imac.  In addition, it seems to be a very slight whistle full time air and occasional pop of static sound.

  I moved the speaker wire to ensure that they were not in contact with anything whatsoever.

  I changed the plug for the speakers.

  I did a reset of the PRAM.

  I did a reset of the SCM.

  Thank you.

  Hello

  The short answer is no the explanation is that the headphones and speakers, both, must be in the State of "Turn off" when you connect or plug in the unit. Amplified as helmet speakers power can be "plugged hot."

  These phone can get dirty sitting and not mobile. Simply power off all devices and 'gently' work the phone jack to plug and unplug some times help you to establish a better connection. If this does not resolve the static electricity, then consider that it should be considered by a professional.

  Bravo!

  When I press the Apple and R keys at the start of my old iMac just boots to the old system rather than start to install new sound system. Help

  Command-r does not work on a 10.6.8 system, you would need 10.7 Lion or better to do. If you try to install a new system and that you have already downloaded, then go to your Applications folder and double-click "install OS X...". »

• Problem with iMac Start Up - file flashes and no sound

  Hello.

  I was using my iMac mid 2007 earlier today, when he started to slow down, with the color wheel appearing whenever I tried to click on something.

  I left only for a few seconds, thinking that he just needed some time, before the screen went all white. I turned off the computer in decision-making, tried to restart, but after several attempts to turn it back on, all I get is a white screen and a file flashing with an exclamation mark on the subject.

  I tried the cmd + R trick, but it does not work and there is also no startup sound, that is, or so I read, when you're supposed to press these keys.

  According to me, the iMac has been updated to OS X El Capitan (10.11), otherwise this was Yosemite, but I don't know what level of the update, I was on. I can't access the computer for you tell all the other details, but I'm sure he had a memory of 4 GB, I have improved the memory myself.

  Thanks for any help you can give me.

  The flashing? means that it cannot find your hard drive. Looks like your hard drive is faulty / failed.

• iMac sound just died

  The sound died today on my iMac.  iTunes opens by itself, and I can't listen to music if I try to play anything.  I checked mute and in system preferences, he has not yet shown built-in speakers, just the headphones and it kept flashing like a neon sign.  Does anyone else know something similar to this?

  There are several possible reasons for the release of its failure. Please take each of the following steps that you have not already tried it. Some may not apply to your model. Stop when the problem is resolved.

  Back up all data before making any changes.

  1. start by the steps recommended in this support article. Do not skip any step. It is the starting point for further efforts fix.

  2 make sure that you have an installation fully updated to Mac OS X.

  3. If you have installed an application called 'Own memory' or any other third party software that is supposed to 'clean' or 'purge' memory automatically, remove it according to the instructions of the developer and restart. You should do this even if the software is not causing the problem, because it is useless.

  4. other third party which has been reported to interfere with an audio software includes the "Boom" and "Samsung Kies". If necessary, uninstall instructions of the developer (not not by dragging something in the trash.)

  5. If a device AirPlay is selected for the audio release of iTunes (or other applications via third party software such as "Wing"), deselect it.

  6. launch the application 'Setting up Audio and MIDI' by entering the first letters of his name in a Spotlight search and by selecting it in the results (it should be at the top). Select output integrated in the list on the left. If the mute boxes are checked, then.

  7. If a red light is visible in the port of audio when its must play, the internal switch is stuck in the position of the digital display. You may be able to release it by inserting and removing of a mini stereo plug of adequate size. If this is not the case, the machine needs to be repaired. Insert any kind of tool in the port can cause damage that is not covered by the warranty.

  If there is no red light, the switch can always be locked in the position of the helmet. Try to clear the same way.

  8 disconnect all devices wired except the keyboard and mouse, as appropriate. If more than one display is connected, unplug all the extra zeros. Restart and test.

  9. If you have a MacBook Air, turn Bluetooth off and restart.

  10 start in safe mode. Do not open a session; Just restart as usual when the login screen appears. When you do, make sure that the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and the sound does not work.

  11. reset the NVRAM.

  12. Reset the SMC.

  13. triple - click anywhere in the line below on this page to select this option:

  /Library/Preferences/Audio

• 21 "iMac 2010 with el capitan making a buzzing sound and won't start not

  I have a 2010 21 "iMac running EL capitan who today suddenly makes a gurgling noise and he wouldn't do anything so I turned it off and tried to put it back on and it continues to make a buzzing sound, as soon as I press the bottom of the power to the rear it hums 3 times then stops and emits a 3 stops... on a black screen. All tips thank you

  Three beeps usually indicate a problem with the RAM.

  See > Startup on computer - Mac Support Apple tones

  Sometimes, modules dispose and sometimes the modules go bad. Personally, I would check and/or replace the RAM modules.

  If you cannot or do not know how to install or check the RAM for yourself...? Next, you need to contact your Apple Store or FSAA and book a service appointment. See > https://locate.apple.com/country

• high sound height that emitting the end of 2013 (about 6 months old) iMac

  Recently, I was informed my iMac 27 "end 2013 (purchased 6 months ago) have been emitting a high frequency intermittent sound.

  It seems to come from the top left corner of the screen, or maybe the left side of the screen.

  How I can find a solution to this problem because I noticed that there are a lot of those who encounter this problem.

  I have AppleCare.

  This is the area where the hard drive so I would say that your hard drive is heading for a serious failure. This looks like a bearing in the drive is screaming in pain.

  If you just bought this as news of Apple, you have the guarantee of one year.

• No sound output on iMac

  My iMac has ceased to be able to output sound.  There is no case that I can trace it.

  I checked in the system preferences, and I haven't had any changes.  The audio output is directed to the internal speakers, and the output volume is intermediate.

  Any ideas on why sound would simply stop working?

  Check that mute is not activated?

  

• Is it possible on an iMac to determine if the sound system working at its optimum level other than take it into a store?

  I recently had a power outage which decreased the output sound on my iMac or on the Yamaha receiver to which it is connected. I'm trying to figure out which. Is there any built-in sound diagnosis can I check to see if my iMac occurs the most of his ability?

  No doubt, but not integrated into the OS X. Unplug your stereo and listen to the computer directly, check your settings in sound preferences, listen to it with a pair of headphones directly connected to the computer.

• iMac will not start. From sound and sometimes Apple, but no further details. How can I get?

  Just got an iMac and it will not start up.  I can get the sound start and, sometimes, the Apple logo, but it stops there.

  Have tried to use 'command-option-P-R' together. Have you tried "D".  Tried "control C".  Are there other possibilities that I could try?

  Install or reinstall OS X from scratch

  Make sure that you have backed up your files because the following procedure will remove all of the hard drive.

  HD recovery start:

  Restart the computer and after the buzzer, press on and hold down the COMMAND and R until the menu screen appears.

  Erase the drive:

  1. select in the main menu disk utility and click on the continue button.

  2. once the charges of THE select your boot volume (usually Macintosh HD) in the

  list on the left. Click on the Erase tab in the main window of THE.

  3. set the type of format Mac OS extended (journaled). If necessary, click

  Security and button all the option data from scratch in a single pass. Click

  the clear button and wait until the process is complete.

  4 leave FROM and return to the main menu.

  Reinstall OS X: Select reinstall OS X and click on the install button.

  Note : You will need an active Internet connection. I suggest to use Ethernet if possible

  because it is three times faster than wireless.

  This should install the version of Mac OS X that you had installed it.

  If this does not work then your hard drive has failed and must be replaced. Please make an appointment at the Apple Store - Genius Bar store and bring it into service. If you are in the United States or is unable to make an appointment in this way, contact your Apple store.

• Sound constantly endangered on iMac

  I have an iMac when the sound came through a set of monitors Personus through an audio interface Focusrite.

  Everything worked perfectly since I installed for more than a year, but now I have a problem where the sound disappears across the system. So, if she's playing a melody via iTunes or play through Amplitube guitar sound just will. To remedy, I have to restart each time the iMac which is a pain closes I have currently open applications.

  I googled similar questions on the forum and google and I can not find a specific resolution for playing audio through external speakers.

  Any comments as to how to solve this persistent bug?

  I should advise that the sound does not disappear while I actively use the iMac, it will only ever if I wake up from sleep mode.

  See you soon

  Try this:

  • Disconnect 'Personus monitors via an audio interface Focusrite.
  • Ensure that the sound from the built-in speakers
  • Allow the iMac sleep
  • Wake up the iMac... is sound?

  If this problem is eliminated by using the speakers integrated, you know it has something to do with the "Personus monitors via an audio interface Focusrite" do not reactivate after your iMac sleep.

• What are the options I have to 'in' sound on a new iMac?

  What are the options I have to 'in' sound on a new iMac?

  Almost all recent Macs I've seen have a Line In port which can either accept a stereo 3.5 mm to RCA, stereo input analog line or a Mini-TosLink digital connection for S/PDIF (2 channels).  If you need more audio input or need to enter that is not as intensive machine - you will need to invest in an audio interface.
