I can not get my mac book air off mute

I can not get my mac book air off mute and it is grayed out in the "system Preferance" sound section page.

OS X Mountain Lion 10.8.3
Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Make sure Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup.app
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so uncheck it.
    Option click the speaker icon, if present and select Internal Speakers.
6. Install Combo Update ML 10.8.3

Yes. You need 2011 or later in order to mirror as it requires the newer processor. The alternative is airparrot, which does it via software.

Can I leave my mac book air plugged in all the time at work, without damaging the battery?

I know people may have asked this questions many times, however I intend on using my mac book air at work and would like know I I can leave it on powered on in the office and the unplugged at night?. Would it damage my MacBook?

Yes. It will not damage the battery. You do not need to unplug it at night. If you use it from the AC charage all the time, then about once every two months you should use it on battery power until the battery drops below 20%. Then fully recharge the battery after which you should allow the battery to "rest" for about one hour. It is OK to use the computer during that time but do not yet connect the AC adaptor. Follow this practice and your battery should have a good life.

HT4199 i can t mirror my mac book air via apple tv.

i bought apple tv 3rd generation and have a mac book air from mid 2012. i have problems mirroring my mac to aplle tv. there is now morroring icon.
how can i set that up ?

First, uninstall Clean My Mac. Third party so called Mac cleaning utilities can do far more harm than good. Your Mac runs maintenance for you in the background.

Restart your Mac after you have uninstalled Clean My Mac.
Hopefully you have a backup of your Bookmarks so then can be reimported back into Safari ..

Hi, I can't sync my Mac Book Air and iPhone5 calendars. I get a message from iTunes saying that the sync server failed to sync iPhone. Any explanations and/or solutions? Thanks.

What can I do to sync Mac Book Air and iPhone 5 calendars if the iTunes message says that 'the sync server failed to sync iPhone'?
Thanks,
Julian

Read the KB. Earlier today I had a fail to sync - I closed my Calendar app and the reopened and all was good.
Sometimes just closing the app the relaunching is all it takes. At other times a reboot of the Mac is all that is needed.

Can you buy a mac book air in america then bring it back to england to use?

I will be going to america in the near future and was wondering whether if id be able to pick up a mac book air from an apple store over there. Should they work over here? Is there anything i should know ? thanks.

Yes, as other posters have said simply remove all packaging. Pick yourself a nice laptop bag and carry it on the flight as hand luggage, and don't declare it to customs! Buy yourself a 13amp US - UK plug and you're fine to connect the power cable to UK mains.
Also, if anything happens to go wrong with your Mac in the UK, so long as you are still in warranty it will be hounored in any UK Apple store.
Good luck.

HT201343 Done everything on the list and can't get the mac book air to recognize the apple tv. How do I get the icon to appear again?

Hello Pauldpetersen,

Everything, Numbers and Pages et al, always default back to US English. To cap it all we sell luminaires (yes this is a word used in our world of lighting design everyday) Mac and Microsoft always default - my docs have more words underlined in red that not. I once found a permanent solution for Microsoft that removed US english - and then the laptop died. Can anyone rid me of this irritation.

GOT IT FIXED! WOW!
I did better than filing a bug report. I went to Apple support, chose chat support. When it wanted $15 or was it $19 I filed an exemption which was a choice on the page, based on the fact that I recently upgraded to Yosemite.
Got the chat fellow and here we go!!!! ;-) First off he sent me this app so he could see my screen. Then he had me do a few things like move the system configuration folder to the desktop and repair permissions. Then he had me reset the SMC and Pram. Nothing helped, all the ghost computers still showed in the finder.
As a last resort he had me reset my Apple Airport Extreme. Wala! Ghost Computers GONE! He said it was a combination of stuff but mainly it was the airport extreme when I installed Yosemite. Something to do with my network. We'll see if it holds or if the problem comes back but as of now there's no more ghost computers in the sharing part of the finder.
Thanks to all who offered suggestions. I hope maybe this helps someone else.

Can not boot from Mac OS X Install Disc 1, G5, Snow Leopard

I have version 10.6.8 installed. Compter is a 2 x 2.66 GHz Dual-Core Intel Xeon. 6GB memory
I want to run Disk Utility and startup from the install CD that came with the computer (the grey one, disc 1, or even the retail disc Mac OS X Snow leopard, the whit one) but I CAN NOT DO IT. So frustrating.
I restart, hold down the "C" key, before the chime, after the chime, every which way, and my Mac always acts as if I am simply restarting, goes right to the login screen everytime. I tried holding down OPTION on restart to choose which to startup from, but only saw the hard drive as an option. I open System Preferences, Startup Disk and the install CD does not even show up as a choice to start from, yet the install CD shows up in the finder.
What am I doing wrong?
Thanks

OK.
According to the knowledge base that model should have shipped with Tiger, 10.4.7.
Going to need some thought here, though. I was going to suggest a possible problem with the optical drive, but you say the DVD mounts on the desktop as a normal DVD would?
Nevertheless, do you have access to another Mac or an external HD with a bootable OS X on it (later than the Tiger version your Mac Pro shipped with)?
If so, try booting from the external, or from the other Mac using Firewire Target Disk mode, and using DU from one of those sources to repair the MP's internal HD, then try the disc(s) again.
