Welcome to Apple Support Communities
Restart and your Mac should start up in normal mode, so you can use speakers again.
If it doesn't work, reset the PRAM > http://support.apple.com/kb/HT1379
If nothing works, open Terminal (in /Applications/Utilities) and type:
sudo nvram -d boot-args
Finally, restart your computer

  • Hello MacHeads: I downloaded Handbrake 0.9.1 for Tiger, so I can upload a homemade DVD for editing in imovie.  Problem is I can't even access Handbrake Help book, because I think my firewall settings are preventing me.  I tried turning off all my firewall

    Hello MacHeads: I downloaded Handbrake 0.9.1 for Tiger, so I can upload a homemade DVD for editing in imovie.  Problem is I can't even access Handbrake Help book, because I think my firewall settings are preventing me.  I tried turning off all my firewall settings.?  IDK if I'm even doing that right.  Can anyone help out here?

    You don't need Handbrake for that if it is your own DVD.
    You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle.
    a DVD is in a compresed format called mpeg2, which is standard across all DVDs. This is what is known as a 'final delivery format' and is not suitable for editing. Because is is compressed, a 4.7GB DVD can hold a two hour movie (dual layer DVDs twice that), whereas the DV stream from a video camera, which runs at about 13GB per hour, is not compressed and IS intended for editing.
    In other words you have to 'reverse engineer' the DVD back to an uncompressed format in ordfer to edit it. There is a penalty for doing this in terms of slight quality loss, but it is one you can live with.
    When you have your DVD as an icon on your desktop, double-click it, and it will open to reveal a TS-Folder containing a number of various files, some called VOB. These are the constituent parts of any video DVD.
    When you have downloaded and installed mpegStreamclip, and purchased and installed the Apple mpeg2 plugin, open mpegStreamclip and drag the entire TS Folder into its window. Then using the various menus available to you (just explore them and you will get the hang of it) ask it to convert to DV.
    That DV file, which will be many times larger than the original TS Folder, and which can a while to create (be patient - make coffee or prune the roses!) is what you can now import into iMovie for editing etc.
    When you have finished doing that, you then have to turn the project back into a DVD.
    mpegStreamclip can be downloaded from here:
    http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
    which is free, but you must also have the  Apple mpeg2 plugin :
    http://www.apple.com/quicktime/mpeg2/
    which is a mere $20.
    Another possibility is to use DVDxDV:
    http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
    which costs $25.
    For the benefit of others who may read this thread:
    Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.

    You can not merge accounts.
    Apps are tied to the Apple ID used to download them, you can not transfer them.

  • Since I upgraded to 10.9.5, my macbook no longer recognizes my external  hard drive. How do I fix this?  External hard drive is a 1TB Toshiba formatted for mac.  Worked fine until latest upgrade.

    Solved the problem by dumping my external HD onto another computer. Re-formatting and re-installing the data.  Not what I wanted to do but it solved the problem.

    Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
    Does the iOS device see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on your router
    .- Reset network settings: Settings>General>Reset>Reset Network Settings
    - iOS: Troubleshooting Wi-Fi networks and connections
    - Wi-Fi: Unable to connect to an 802.11n Wi-Fi network      
    - iOS: Recommended settings for Wi-Fi routers and access points
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

    My iPhone 5 suddenly stopped opening the Apple Mail app.  It had worked flawlessly for years, but just stopped.  It worked on my iPad, and of course on the computer.  What's going on, and how do I fix it?  I've turned the phone on and off several times, soft reset several times.  There was no change in any settings when this happened, nor any new apps were added.  Thank you for any help you can give.

    Does it not work either way? Sending and receiving? Did you check the settings and make sure that nothing has changed? If you can receive email, but not send it, check the outgoing mail server setting. Make sure that your username and password are in there.
    Settings>Mail, Contacts, Calendars>Your email account>Account>Outgoing mail server - tap the server name next to SMTP and check in the primary server and make sure your username and password are entered and correct - even if it says that the password is optional.

  • How do I turn off Sleep/Hibernation/Startup Beeps and Sounds?

    I have a Lenovo Thinkpad x200 running vista ultimate. type 7454-cto
    How do i turn off these annoying beeps that sound every time my computer goes into and out of sleep and hibernation.
    I've tried turning the sound scheme to "No sounds," but the beep still sounds when computer enters and exits sleep and hibernation.
    If i turn on "mute" before i enter sleep or hibernate, the beep does not sound (which is what i want). Unfortunately, its impossible to turn on MUTE when im trying to bring the computer out of sleep or hibernate (which makes it very distracting to turn the computer on during class). 
    Solution:
    Enter BIOS by pressing F1 during boot
         >Config
                  >Beep and Alarm
                             Set Power control beep to [Disabled]

    Solved!
    Go to Solution.

    Just tried it out and the BIOS solution works.  Here's the funny part: After disabling the beep in BIOS config, I started windows and opened Power Manager again.  Sure enough, the "beep when power state changes" option was finally disabled.  Just for kicks, I tried to see if I could enable it again in Power Manager.  I enabled it just fine in Power Manager but when I tried to disable it again I COULDN'T!  I had to back into the BIOS again to disable it.  So the deal seems to be that Power Manager will allow you to turn on the annoying beep, but if you want to turn it off, you need to do it in the BIOS settings.

  • After replacing wifi antenna wifi is still dimmed/greyed out.  Bluetooth works fine.  How do i fix this issue? Could there be another part that needs replacing?

    This article offers some suggestions which may help: iOS: Wi-Fi or Bluetooth settings grayed out or dim

  • How do I get an Internet Explorer on my Mac OS X, I need it to run work programs?

    How do I get Internet Explore on my Max OS X, I need it to run work programs?

    If you are running an intel machine, you have Boot Camp on your machine, use it to install Windows on the partition it makes, and then you can use Internet Explorer.  If you don't have an intel, you can use a virtual windows program, something like Parallels or VM ware.
