Hi, I turned my macbook pro off before I went to sleep, and this morning when I awaken. I can't seem to use the volume at all! I went to system preferences sound output BUT everything is light grey and it some-how looks like I don't have permission.

Hi, I turned my MacBook Pro off before I went to sleep, and this morning when I awaken. I can't seem to turn up or down my volume. It comes up with all the volume bars and a little circle sign with a diagonal line in the middle, like a stop sign. I have gone to system preferences > Volume > Output BUT all my volume preferences have gone all light grey and wont let me access them.
Anyone help?

Hi EmalooneyToons,
Welcome to Apple Support Communities!
Take a look at the article linked below, it provides some suggestions for troubleshooting audio issues on Macs and when to setup service for your device, if needed.

The choice of headphone jack is not showing up under the system preferences - sound output options. Therefor, my speakers suddenly do not work with my iMac

On my Intel based iMac, OS 10.6.8, my speakers suddenly were not transmitting sound. When I checked the System Preferences, Sound output, the headphone option was no longer available. This has always worked in the past - what is up?
Anyone have any suggestions???

Applications > Utilities > AudioMIDI Setup.app
Audio Devices window
Side Bar
Click the Built-in Output.
Under Mute any of the boxes checked? If so uncheck it.
Plug in the headphone and check whether in the output headphone shows up in the same panel.
If so, you can adjust the volume there.
Reset SMC and PRAM.

Hi nitramred,
To start troubleshooting this issue where you are unable to adjust the volume after receiving a call, please go ahead and first force close all of the apps currently running on the device, and then reset it by following the steps in the articles below.
iOS: Force an app to close
Turn your iOS device off and on (restart) and reset
Take care,

What backups do you have?

I can't seem to use the 'Check seats' link on Delta when I use Firefox but Safari works fine. I get the message 'not available at this time' when using Firefox but when I go to Safari it works fine.

I can't seem to use the 'Check seats' link on the Delta Airlines site when I use Firefox but Safari works fine. I get the message 'not available at this time' when using Firefox but when I go to Safari it works fine. I love Firefox but this sucks!

That issue can be caused by corrupted cookies.

System preferences 'sound' closed but then re-opens. Can't close :(

My iMac has just started behaving strangely. The System Preferences 'sound' window opens but after closing or minimising it re-opens.
Forced close by cmd+option+esc but symptoms remain.
Another symptom shows within 'Launchpad' when several Apps flicker and show the delete 'X'.
Restarting system or logging in as a guest doesn't change the situation.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

IMac 27-inch system preferences sound output

On the output tap of system preferences - sound, I just have on select devices "headphones." It's that normal? I expected it would have to choose between "Internal Speakers" and "headphones." I want leave my stereo plug-in to my iMac to play music, but for the rest just want to heard it through the iMac's own speakers.

Yes that is normal. You cannot use both at the same time. To use your Internal Speakers you must unplug the external device.

Is it ok to NEVER TURN my macbook pro off , but when finishing work put it to sleep ?

I have a setup that makes me use the HDMI while closing the mac. yet, each time I need to open the macbook pro I'll have to remove all the usbs and thunderbolt plugged in. So I want to switch it to sleep rather that Shut down. so when I press any button on my external keyboard it turns on.
The only concern is "will this harm my macbook on the long run ?"
I'm using a Macbook Pro 15" with retina display
Intel Core i7
16 GB RAM
500 GB Flash Storage

I don't know the official answer to this, but I rarely turn mine off, sleep only for years now. Turn off and reboot for sofware installs and such, but it has not been a problem.
Someone else will surely address this as well.

Mac Air(OSX) stuck on mute! no devices visible in System Preferences Sound Output/Input

I have a MacBook Air, Version 10.6.8, Processor 1.6GHz Intel Core 2 Duo.
My Sound is stuck on mute:
-when I go to System Preferances>Sound and go to Output or Input, under "Select a device for sound input/output" there is nothing listed. There at the bottom also the Mute checkbox is also stuck and can't be changed.
It always gets stuck after leaving it in sleep longer (3x till now).
1)The first time this happened, I restarted the PRAM (OPTION+COMMAND+P+R after restarting it) and it helped. The sound worked after that.
2) The second time the method from 1) didn't work, so I tried updating COMBO and then I restarted the SMC (CONTROL+OPTION+SHIFT+POWER BUTTON) and it helped everything was fine after that. The sound worked after that.
3) The third time (all three time in a row) nothing worked (I tried):
      -restarting the PRAM
      -restarting SMC
      -Reparing Disk Premissions in "Disk Utility"
      - I tried deleting some files in the Library>Preferences>...
      - I tried restarting
      - I tried inserting headphones (still no sound)
      - I tried playing some music in the Garage Bend
       - I tried restarting
       - I did not update COMBO the escond time (it would be crazy to update combo everytime this happens, and it happened three days in a row)
Please help me. I have no sound for a week!!!

On a Macbook Pro, I cannot print web pages with Firefox v 3.6.13. I can print if I use Safari, but no Firefox. Any ideas??

When I try to print, it does not even appear to "connect" to the printer software. Normally, a printer icon will pop up in the taskbar, but this does not happen with Firefox. Also, in Mac, you have the option of saving the webpage as a pdf document. When I try it, it only results in a blank page. The Browser that comes with a Mac, Safari, works fine and prints. Not sure if it's a setting in Firefox or something else.

Some gestures have been removed in Firefox 4+ versions.
You can restore the zoom feature by changing the values of the related prefs on the about:config page.
* browser.gesture.pinch.in -> cmd_fullZoomReduce
* browser.gesture.pinch.in.shift -> cmd_fullZoomReset
* browser.gesture.pinch.out -> cmd_fullZoomEnlarge
* browser.gesture.pinch.out.shift -> cmd_fullZoomReset
* browser.gesture.pinch.latched -> false
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
*Use the Filter bar at to top of the about:config page to locate a preference more easily.
*Preferences that have been modified show as bold (user set).
*Preferences can be reset to the default via the right-click context menu if they are user set
*Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean)

MacBook Pro mid 2010 putting itself to sleep and restarting on wake-up?

My mid 2010 MacBook Pro has recently started having a lot of problems. It will put itself to sleep whilst I am working on it, and when I try tp wake it up it restarts showing a message saying 'Your computer restarted because of a problem. Press any key to continue..' however it doesn't tell me what the problem is. This can happen every 5 minutes or once an hour but it is becoming very irritating. I have previously done a PRAM and SMC restart, they made no difference. I can't think of any recent programmes I have installed to cause this problem, other than updating to mountain lion 10.8.5. Im not very computer savvy either, so understanding much of what is online is not easy.

You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:
MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
Print the first page of the panic report, and the support page linked above, and bring them with you.
Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair. The model was discontinued in February 2011, so the replacement program will be ending quite soon.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Sometimes the replacement part is also defective, so be prepared for that possibility.
If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
*An SSD doesn't need to be zeroed.

Need to run macbook pro in 32 bit mode to run and external modem how do i change from 64 bit to 32 bit

I have a macbook pro which i presume runs in a 64 bit mode. living in a country without broadband i need to use a 32 bit modem, can i change the system to run this modem at 32 bit as it wont load at 64?

Reboot holding 3 and 2, see if your modem works.
Rebooting again sets it back to 64 bit.
If 32 bit works then your fine, for now, but eventually your going to have to go 64 bit.

My macbook pro's screen is a pixelated green and purple. How do I fix this?

It's very annoying and my computer is very new. I know I haven't intentionaly damaged it.

Woke up this morning and this three green "dashes" and three amber "dots" is what my airport express 2nd gen is doing. Wasn't broadcasting wifi.
So far hooked up over ethernet to my laptop and it passes through internet from the modem.
Tried:
Soft reset
Hard reset
Factory Default reset
All of it goes back to the 3 green dashes and 3 amber (yellow) dots. I unlike the original poster didn't apply power to the analog jack.
I will try multiple Factory Default resets and see if this helps.
Also used airport utility 5.6.1 for Windows 7 before the hard/factory resets and it wouldn't accept my well documented router password. Factory reset and now it won't connect.
Get:
An error occurred while trying to access the Apple wireless device. Make sure your network connection is valid and try again.
Error -6742
Only option is "ok" and this happens no mater what you click on for the Airport Express. Funny thing is I bought this one year and three weeks ago. Ha.
Going to try some more hard resets to see if that works. Tried to be detailed and write the text in different ways since I was unable to find this search first even though this is my exact problem I'll try and check back later.

I was able to access "share" my desktop using my laptop until I had to reinstall Lion onto my desktop. No w when I try to access my desktop - all I see is the public folder not my desktop etc. I went into system preferences to sharing, but..

I tried checking off everything but it doesn't give me my desktop.

HT5035 I can't seem to use the balance on my account in the itunes store without putting in the code of the original card. This has never happened before and I don't have the original card. Help please?

I can't seem to use the balance left in my i-tunes account without re-entering the code from the original i-tunes gift card. I no longer have the card. How can I purchase music using the balance without the card?

the code from the original i-tunes gift card is not required again once redeemed.

Hi, I turned my macbook pro off before I went to sleep, and this morning when I awaken. I can't seem to use the volume at all! I went to system preferences sound output BUT everything is light grey and it some-how looks like I don't have permission.
