Hello!  I have an iMac that I lose the audio output for certain profiles.  The audio output will work on one profile, but when switching to another profile, I lose the audio output.  I've reset the NVRAM/PRAM and that hasn't solved the problem.  Help!

Hello!
I have an iMac (running iOS 10.6.8, not upgraded to Lion) that I'm having audio issues with.  I have 5 profiles on this machine.  The audio output will work fine out of one profile, then when switched to another, the profile will not have any audio output at all.  Rebooting the machine will occasionally solve the problem.  Administrator permissions are not the issue since this has also manifested itself on the administrator profile. I've also reset the NVRAM/PRAM and that hasn't helped.  All my software is up to date and I recently upgraded the RAM to 2x2GB sticks.  This problem was existing prior to the RAM upgrade. 
Any suggestions?  Thanks in advance!

Hi Tony,
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

    Hi, my phone is showing this [N] symbol on right side of the status bar for certain apps like Facebook, Whatsapp, etc. Any one knows what it means?

    BTW it normally only shows if jailbreaked and also tells you that those apps are running in the background so the notifications can be poled .
    Be aware your battery life will degrade !

    The bottom of that article says to contact an authorized service technician.  You may also find that simply replacing the PRAM battery (the coin shaped battery) helps.   Note: if you have any capacitors that are labelled X on their top (as opposed to just K), you may have the problem of the leaking capacitors which required a power supply and/or logicboard replacement.  The leaking capacitor was an industry wide problem.

    If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
    Otherwise*, start up in Recovery mode. When the OS X Utilities window appears, select
              Utilities ▹ Terminal
    from the menu bar at the top of the screen—not from any of the items in the OS X Utilities window.
    In the window that opens, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
    Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
    Select
               ▹ Restart
    from the menu bar.
    You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
    *Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

  • Having horrible service with 4GLTE I have had 3G for several weeks (I am not the only person I know having this problem), I have reset my network settings and it did not resolve the issue.  I am also unable to send SMS and text messages without them eithe

    Having horrible service with 4GLTE I have had 3G for several weeks (I am not the only person I know having this problem), I have reset my network settings and it did not resolve the issue.  I am also unable to send SMS and text messages without them either failing or not sending at all.  Is there an outage in the Cleveland, Ohio area (zip codes 44129, 44134, 44137) or anything else I can do to resolve this issue?

    Not that I'm a Verizon employee, but I have experience in the field. An LTE tower will only extend up to, on a perfect day, with no elevation, 6-7 miles. On a typical day, you will be lucky at four (4) miles. The three ZIP codes you've given are all within about a 12 mile radius. That would mean that 2-3 towers are currently down at the same time, and Verizon would know about it within the hour. Being it's Cleveland, I'm sure they would receive numerous calls regarding an outage of that size.
    My point is that if you're having issues in all three ZIP codes, chances are it's a phone issue. If you're handset is simply not receiving LTE, but still receiving 3G, that would signify a SIM card issue. You need to get your SIM card replaced.

    - Reset all settings

  • Hello i have a imac 8.1 and my volume down button stopped working..

    i had the maverick osx and i install some vst for ableton before that happend but i make format the disk and clean install the osx lion and it doesn't fix the problem.. any help ??

    Very simple take it to an Apple Store or AASP and have it professionally diagnosed. Anything else would be guessing. Do NOT spend a penny on it until it is professionaly diagnosed otherwise you stand and excellent chance of throwing good money after bad.

    I have not installed mavericks. should I install?
    Thanks!!

    It requires 10.9 or later.
    Upgrading to Mavericks
    You can upgrade to Mavericks from Lion or directly from Snow Leopard. Mavericks can be downloaded from the Mac App Store for FREE.
    Upgrading to Mavericks
    To upgrade to Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Download Mavericks from the App Store. Sign in using your Apple ID. Mavericks is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
        OS X Mavericks- System Requirements
          Macs that can be upgraded to OS X Mavericks
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later

    That is precisely the WRONG thing to do. You should never delete, but uninstall.
    Now you need to look for, download and run the Adobe CS Cleaner tool.

  • Failure to reset Mac's PRAM and NVRAM

    I wish to re-set my Mac's PRAM and NVRAM. But when I hold down Command-Option-P-R, it doesn't allow my computer to start up.
    It turns on the grey screen, makes the start up noise, but then drops back out again, and it keeps on doing this in a loop.
    How do I resolve this?
    Can you not rest your PRAM / NVRAM if you operate on split platforms os x / win.?
    Many Thanks

    That's exactly how it works.  See Resetting your Mac's PRAM and NVRAM.

    I have an existing ipod that I use with my mac. I am trying to connect an additional ipod to it but when I try and register, it just brings up the existing info. I don't want to lose the original info or library - just create new for this device. Pls help...

    We are starting from the beginning like its a new ipod starts out asking language, country,location services,choose a network,and when we get to "setup ipod touch  " there are 3 options 1..setup as new ipod, 2.restore from ipod backup 3 restore from itunes backup and when we hit setup as new ipod and click next it comes up with sign in with apple id or create a free apple id  we clicked create a free apple id....then comes up with bday,1st name last name, use your current email address, get a free icloud email address or change email address and THIS is where we have problems....if we hit change email address it means that sis's stuff goes under his name and moves all her stuff to this older ipod which the brother does not want. sorry this is so long but its the only way I knew to do it.
