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

Right-click or Ctrl-click on the highlighted line and select

Services ▹ reveal in Finder (or just to reveal)

Go ▹ go to the folder...

    Since the upgrade to 2015 CC and change my site to a paid site, can my customers is more updated of the site through the browser update. When they try, parts and pieces of the site appear and they can see what it takes to update. It's about to make me lose my client. Help, please.

    We have identified two questions:

    (1) muse implements a markup bad comment, causing in the edition (IBE) browser to display the page properly. Only, this affects IBE and does not affect the published site. The combination of page that causes the bad markup is still TBD.

    (2) IBE does not account for the bad markup that leads to incorrect DOM, leaving IBE unusable.

    We have a fix for IBE (as BC) who is ready to be tested. We will update this thread when the fix is on.

    Sorry for the inconvenience.

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that disables certain parameters, disables most Add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • In Firefox 29,0 and above, click on the menu button

      click Help

      then select restart with disabled modules.

    • In previous versions of Firefox, click on the Firefox button in the upper left of the Firefox window and click help (or click on help in the Menu bar, if you do not have a Firefox button) and click on restart with disabled modules.

    If Firefox is not running, you can start Firefox in Mode safe mode as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. Please follow the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Since the upgrade limit "Screen time" no longer works.

    I understand that with Win 7 hours available per day has never worked.  So let's take that from the equation.

    Before the upgrade, I could sign in security for the family of any device to add or remove time.

    Since the upgrade, he can sign where he wants, regardless of my standing orders.

    I see some nonsense now, I have to refresh, by signing with your family on that. computer, using my connection and click Refresh.

    So are saying you that I can change is no longer permit time by logging parental control of another device?

    I have to sign into the computer, then connect to Windows security and THEN refresh?

    This is a great strength of parental control that I could change time since any device license and ask them to work.

    Now I add time, he cannot sign I revoke his time and nothing happens.

    Good news, I can (once again) to change the authorized beginning and end of time through parental controls of a device and apply to the other.  So at least I can change the time at will (since I can agree is more blocks of several times a day.)

  • Since the upgrade to 10.11.4 won't open my app store.

    Since the upgrade to 10.11.4 will not load the app store my mac icon. It opens, but all I get is a spinning wheel.

    Please test after taking each of the steps that you have not already tried it. Stop when the problem is resolved. Back up all data before making any changes.

    Sometimes, the cause of the problem may be an Apple network, whereby failure cases none of the steps below will have no effect. You just have to wait for the failure be fixed. This should rarely, if ever, take more than a few hours.

    Step 1

    Connect to the App Store by selecting Sign In in the Store menu. If you are already connected, disconnect and then reconnect.

    Step 2

    Remove or disable "Little Snitch", or any other third party software like that blocks outbound connections to network, in accordance with the instructions of the developer.

    Step 3

    In the menu bar, select

     ▹ System Preferences... ▹ Network

    If the preferences window is locked, click the lock icon in the lower left corner and enter your password to unlock it. Click the Advanced button, and then select the Proxies tab. If any proxy are selected, make a note of and then deselect them. You need not change the bypass or the FTP settings. Click OK, and then apply. Test. The result may be that you can not connect to any web server. Restore the previous settings if necessary.

    Step 4

    Log off or restart the computer.

    Step 5

    Start in safe mode and log on to the account of the problem.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

    Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

    The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

    After testing, restart as usual (not in safe mode).

    Step 6

    If possible, connect to a different network and test.

    Step 7

    Reset the NVRAM.

    IE7 and Mozilla worked very well, but since the upgrade to IE7 will not be the default browser. Every time I run the IE7 application it says it is not the default browser. How to solve this problem.

  • Something Apple regarding 10.11.4 gel and requiring a hard reboot?  I had several incidents since the upgrade (supposedly) gel to 10.11.4

    I'm having a problem with my Pro MacBrook retina (end of 2013).  Since the upgrade is supposed to 10.11.4, I eperienced several system freezes; all

    that required a hard reboot.  The machine is Core i7 to 2.3 gHz, 16 GB 1600 mHz DDR3 ram, 512 GB ssd.  Safari v.9 (1).  It is obvious that the other users are

    having the same experience - any word from Apple regarding a solution?  I expect this kind of thing from Windows, not Mac machine...

    There is no systemic problem with 10.11.4 gel. Where are you this information? If you get it from forums like this one do not forget that the few people who post here post about issues they know. Their messages do not represent millions of people, not problems.

    A lot of questions like yours goes back to 3rd party apps incompatible or drivers that have not been updated for 10.11.4. Provide details of your question and we will try to help you.
