My macbook pro volume is locked. there is a circle with a line through it when i press the volume buttons but no volume will sound. music and videos will not play and there is no red light on in the headphone jack.

Any suggestions of what could be wrong? or how it can be fixed. I have not updated it or anything. this just randomly happened about 2 hours ago. I tried looking for answers but nothing has worked so far.

I tried all of the fixes above and quite a few others like resetting the pram and nvram and what finally worked for me was resetting my sound card from Terminal. Open Terminal and enter the command sudo kill -9 `ps ax|grep 'coreaudio[a-z]' | awk '{print $1}'`. It will ask for your password, enter in your password and press enter. The sound card will be reset and your audio and volume control should be restored..

Have to keep refreshing Firefox to see messages received on Facebook, and videos do not play in Firefox 3.6.9. What's the cause?

While on Facebook, I always need to refresh the page to know I received a message, comment or whatever else. Also, while on game sites such as Gamespot, Firefox does not play any videos. All this is happening in version 3.6.9. What is the cause for this?

How ram does your machine have have you tried shut the machine down pull the power plug for a few minutes and plug it back in and restart the computer. The only thing I can think of is Low onn Ram or the speed of your connection. It might be the player you are using as well. download VLC Player itwill play everything.

I updated my Macbook Pro last week to Lion. I went to go import pictures from a memory card to my iPhoto, but only a portion of them loaded before my iPhoto froze and I had to Force Quit it. Now iPhoto won't even open... Help!

Please! I need an answer fast!!!!

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Mac book pro stops responding after Maverick OS restart. Currently have a circle with a line through it after 20+ hours. Tried to shut it down and use the Time Machine to restore but no response. How can I restore with Time Machine if it will not start?

sonjadg,
you can purchase a replacement pair of grey installation DVDs for your MacBook Pro from either Apple or iFixit. If Startup Manager is only showing an OS X Installer volume, then it sounds like the Mavericks installer had a problem midway through its installation process. To fix this, you’re going to need to erase your internal disk and reïnstall your original version of OS X from the grey Mac OS X Install DVD, use Software Update to get it back to 10.6.8 (presuming that your MacBook Pro originally came with Snow Leopard), and then restore from Time Machine.

The sound doesn't work. It's set appropriately in settings, the volume is turned up all the way with the side buttons, but no volume. When we try to play songs, it acts like it's going to play and then goes back to the play list. Restored and still no

It's set appropriately in settings, the volume is turned up all the way with the side buttons, but no volume. When we try to play songs, it acts like it's going to play and then goes back to the play list. Restored the device and still no sound.

Try A and B
(A) Restart iPad
1. Hold down the Sleep/Wake button until the red slider appears.
2. Drag the slider to turn off iPad.
3. Turn iPad back on, hold down the Sleep/Wake until the Apple logo appears
(B) Reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
Note: Data will not be affected.

I go to tools then options when I try to open saved passwords it brings up a red circle with a line through it and wont open

I go to tools and the options and I can't open any of the tabs at the top Eg I go to exceptions and I get a red circle with a line through it.This is the same for all of the options that have exceptions and saved passwords.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
* https://support.mozilla.com/kb/Safe+Mode
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Though I have doubts for success, you might try a SMC reset. It can do no harm. Otherwise, barring suggestions from others, the Apple Store or qualified repair facility is the last option.

I updated my computer to the new software and now the iPhoto has a circle with a line through it. When I try to update, it pops up to say "These apps cannot be accepted by your apple id". Then will say "update unavailable with this apple id" how do i fix

I updated my computer to the new software and now the iPhoto has a circle with a line through it. When I first try to open it the pop us says: "You can't use this version of the application "iPhoto" with this version of OS X. Version: 9.2.1" When I try to update, it pops up to say "These apps cannot be accepted by your apple id - These apps were already assigned to another Apple ID and they will be available in that Apple ID's purchases list. If you don't have access to that Apple ID and want to receive future updates, you will need to purchase the application". I checked and there is nothing under the "purchases" in my App store. Then will say "update unavailable with this apple id - This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or canceled." Then the third pop up says "We could not complete your request. There was an error in the App Store. Please try again". Just want to know how do to fix.

After I upgraded to Mavericks I was also having this message when I tried to update. There was a previous post about this problem which offered this simple solution which worked for me:

Got it! Thanx. What I did was go to my account, check that they had my new ID and Password which they did, then hit reset button. All fixed.

My songs and videos are not playing.

Hello,
My songs and videos are not playing in the iPod. If i play music on online in iPod, it works. So, please reply me as soon as possible.
Thank You,

I have had similar problems in the past, but not with so many songs... If you got them on the iTunes store, and there aren't so many, just re-download them, this happens to be sometimes. I'm guessing that there was some error during the download. sorry.

Hi,
Try a clean installation of the flash plugin/activeX as follows.
First, download the Flash uninstall utility on the link below and save it to your Downloads folder.
Flash Player Uninstaller.
When the download has completed, close all browser windows, open your Download folder and run the uninstaller. After this has completed, restart the notebook.
When windows has reloaded, download and install the latest version of Adobe Flash. Note: You may want to deselect the option to include McAfee Security Scan Plus before downloading.
When the installation has completed, restart the notebook.
If the above doesn't correct the issue, then try the following.
First of all, download and run the Shockwave uninstaller on the link below.
http://fpdownload.macromedia.com/get/shockwave/uninstall/win/sw_uninstaller.exe
After this has completed, restart the notebook.
When windows has fully reloaded, download and install the latest version of Shockwave on the following link.
http://get.adobe.com/shockwave/
Again, after this installation, restart the notebook.
Regards,
DP-K
