Suddenly my MacBook Pro 13-inch is giving a low sound output when compared to the first time. What should I do?
If you are noticing issues with the speaker volume on your MacBook Pro, you may need to reset the NVRAM:Your Mac stores certain settings in a special memory area even if it is turned off. On Intel-based Macs, this is stored in memory known as NVRAM; on PowerPC-based Macs, this is stored in memory known as PRAM.Information stored in NVRAM / PRAM includes:Speaker volumeScreen resolutionStartup disk selectionRecent kernel panic information, if anyIf you experience issues related to these functions, you may need to reset the NVRAM or PRAM. For example, if your Mac starts up from a startup disk other than the one you've specified in Startup Disk preferences, or if a "question mark" icon appears briefly when your Mac starts up, resetting NVRAM / PRAM may help.You can use these steps to reset your NVRAM:Resetting NVRAM / PRAMShut down your Mac.Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.Turn on the computer.Press and hold the Command-Option-P-R keys before the gray screen appears.Hold the keys down until the computer restarts and you hear the startup sound for the second time.Release the keys.After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.You can find the full article here:About NVRAM and PRAMhttp://support.apple.com/kb/ht1379
How do I disable iTunes from popping up in Mac OS?
The solution to this -- at least the one I know of -- is bizarre. Additionally, it doesn't disable launching iTunes when F7/F8/F9 are pressed, you need to do something different for that which I will mention after the main solution.To stop iTunes from automatically launching when you plug in headphones or Bluetooth audio devices, go to "CDs and DVDs" in System Preferences (this was hidden for me, but you can customize which areas of System Preferences are visible using the Customize tool under the View tab in the menubar when System Preferences is open) and deselect any options where iTunes is the selected choice. For some reason, this just works. No clue why.This should work, but I can make no guarantees as plugging in headphones or Bluetooth audio devices can have different effects on different computers depending on software and the connected hardware. Additionally, "CDs and DVDs" may not even be available on computers without a built-in SuperDrive, but I'd imagine it would be since you can plug in an external SuperDrive and use that instead.As for disabling iTunes from automatically opening when you press F7, F8, or F9 (the rewind, play/pause, and fast-forward keys on Apple keyboards) you need to switch the function keys to their default uses. This is done under the "Keyboard" section of System Preferences, where you must deselect "Use all F1, F2, etc. keys as standard function keys". Note that this will also disable the other custom keys, such as screen brightness and Launchpad.
My MacBook has stopped showing 'Internal Speakers' in the Sound System Preference. I am not able to listen any audio. How to can this be fixed?
Did you plug anything in/change anything?You may be able to fix this by going to preferencesFirst, disconnect any external audio devices from your computer. Also disconnect any cables from the USB, FireWire, or 3.5mm audio ports.From the Apple () menu, choose System Preferences.Select Sound.Click the Output tab, then select Internal Speakers. If you don’t see Internal Speakers as an option in the Output window, contact Apple Support.If the volume slider is set low, move the slider to the right and test again.If the Mute checkbox is selected, deselect it and test again.If you still don’t hear any sound, contact Apple Support.https://support.apple.com/en-us/...Check the line-out port on your MacIf the Output pane lists Digital Out instead of Internal Speakers, check the line-out port on your Mac.First, disconnect any external audio devices from your Mac. Also remove any cables from the USB, FireWire, or 3.5 mm audio ports. Then check to see if the line-out port is lit by a red light. If it is, your Mac might need service.
Why does my sound get locked on my MacBook Pro and how can I fix it? Is this a big enough problem that I should be taking it in to the store. It has happened to me maybe 3 or 4 times and I have owned my laptop for about a month.
This answer comes very late, but if you are still having this issue here is what to do:Look in the Sound control panel in System Preferences under the Apple menu.Make sure Input is set to microphone and Output is set to Internal Speakers.Open Audio MIDI setup; it is in the Utilities folder within the Applications folder.Make sure that it is set to Built-in Output.Sometimes these settings get messed up. Adjusting them should fix your issue. If not, try resetting the parameter RAM by restarting and holding down the “P”. “R”. and “Option” keys until the computer automatically restarts itself three more time. Then check the Sound settings again.
How do you transfer photos from a Samsung Reality to a Mac OS X?
I've tried everything I can think of. I thought I had it with Bluetooth but I hit the 'Send' option and sent to many things, and didn't have any idea what I was doing. Can someone please help?
Why does my Mac's sound balance keep changing?
I had this problem for years and even blogged about it. I did eventually find an Apple support page that gave some explanation. My old link to that page no longer works, but here is some of what it said:In some cases the audio balance may unexpectedly drift towards the left or right channel. This can happen if you rapidly press the volume up or down keys while the computer's microprocessor is under heavy load.I don't recall having had the problem in the last couple years, though I couldn't say whether that's just good luck or they fixed it. Anyway, maybe this at least makes it less baffling.
Why is my iMac randomly shutting down? How can I fix it?
Well, let’s see. It could be the physical power switch. It could be the motherboard. It could be the power supply. It is possible, but less probable, that it is a component like a hard drive. Better to consult SupportNow… it also depends on what “won’t shut down” works out to be. If every time you tell it to actually Shut Down, it looks like it is going to, and it just restarts…. that’s different from if you tell it to Shut Down and it kills the OS, and the screen goes black… but it just doesn’t turn off.And that is different from if you tell it to Shut Down, and the OS keeps throwing the message at you that there is a program or service that it needs to shut down but can’t, and even when you tell it to just shut down anyway, it comes up with something new. See.. that could be all on the OS, with no hardware component.So you have to diagnose the problem. You have to try different things. Is this a desktop or a laptop? If it is a desktop, open it up and examine the capacitors after you kill power to it. Are any of them blown? Do you have another power supply to use to test the system with? When did the problem start?You track the problem back. They make Power Supply testers you can use to test your power supply with.

How do I put all of my songs into one folder?
I can show you how to do this. On step 4 I realized that there might be a kink if other people have music on your computer. It made the instructions kind of long. But, they're only long because I tried to be as detailed as possible. I think there's a feature in Windows that lets other people access your desktop. If so, I could fix it in seconds, myself. (It's an option.) If these instructions are too complicated, I suggest learning how to use the "library" feature on your media player (I explain it more at the end.) 1. Go to the bottom-left corner of your Windows desktop, and press the "Start" button. Then click on "Search". 2. A window will pop up. On the left it says "what do you want to search for?". Pick "Pictures, music or video". 3. It will give you checkboxes for each: pictures, music and video. Check the "music" box. Hit "search". 4. It will list every music file on your computer. If more than one person uses your computer for music, then their music is going to show up too. If that's true, right click in the blank space, and click "view details". There will be a column labeled "in folder". Click that once, so it will sort the column. The list of mp3s should now be divided so that the "in folder" column should show a list of your mp3s all in one group. Click and drag the mouse to select all of Your music. Then click "edit", then "cut". If every single one of these songs are yours then you don't have to click and drag. Just click "edit", then "select" all. Then click "edit", then "cut". 5. Now figure out where you want your single folder to be (like "my music" for example). Go there and right-click in the blank space. Then select "new", "folder". You can name the folder if you want. 6. Now open that folder you just created. In the blank space, right-click and press "paste". It will put all the music files in that folder. Just so you know, there's probably another way you could solve your problem. Use the "library" feature on your media player. It would display all your songs in one list, so they can be sorted and searched through quickly. I think it lets you load your mp3 player more easily too. It's a very nice feature.
