    Have you tried turning up the audio? This may sound very obvious, but if the slider is all the way down you would have no output. Let me know if you need assistance with this.

Usually a problem with your audio jack. The jack detects an optical plug and switches to optical audio. Clean it with a compressed air can. Otherwise The apple store will probably help you. If not there are third party places that will find out what's wrong. If you want to do it yourself, the good news is, it'snot too hard to open it. Here is an Macbook Repair Guide that shows how to open an Macbook. Just open it and let it try, clean off any corrosion you can find. If you want somebody else to do it for you go to iPad Repair NYC.

Bought brand new Apple MacBook Air from Amazon. It has a username and PASSWORD. Thus I cannot get into my own new computer. What do I do?


If you mean that the very first time you started the computer, you did not get a chance to set it up, then you should return the computer to Amazon or to your nearest Apple Store. Although it is possible to change a password from the Restore screen, you should return it because it is not a new computer, and because it might be compromised.

Pairing MacBook Air (2012) with Aluratek 30 pin bluetooth audio receiver please help


I'm not clear what "30 pin" refers to. It sounds irrelevant to your question or am I missing something?

Try this:
Go to System Preferences, click on Sound. Make sure you are on the Output tab. Select your device.

Why can't I play music from my iPod on my TV via a stereo mini to RCA adapter?


You could be trying to connect your iPod output to your TVs audio output. Can't be done. "Composite input" has nothing to do with what you are trying to accomplish.

Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

Digital Audio out in MACBOOK PRO.


Connect external speakers, headphones, or optical digital audio equipment. The headphone / line output jack accommodates optical digital audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used. For digital audio, a standard Toslink cable with a Toslink mini-plug adapter can be used.
You can find the Digital to Analog converted:
