Why is my MacBook Air muted?

I can't hear anything when I play songs or videos or anything. I didn't even press the mute button and my volume is maximum. I can't even hear anything when my earphones are on. Why???
Thanks

Please take each of the following steps that you haven't already tried. Test after each one. Back up all data before making any changes.
1. Set the default startup disk.
2. Disconnect all wired peripherals except those needed to start up. If there's no change, reconnect them
3. Reset the System Management Controller.
4. Reset the PRAM.
5. Reset the printing system.

Why does my Macbook Air make a single buzz/beep?

Why does my Macbook Air make a single buzz/beep every time I open it or turn it on? It doesn't happen after again after the initial buzz. If I open it after it has been sleeping, it starts up and then there is a buzz. This has only happened since I downloaded iOS Maverick.

Beeps on startup:
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images.
5 beeps = processor is not usable

Why is my macbook air so slow?

why is my macbook air so slow?

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the system log for messages that may indicate a hardware fault. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|nspace-h|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the 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.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

HT1338 why is my MacBook Air running slow and I bought the 11 inch with all memory and turbo boost

why is my MacBook Air running slow and I bought the 11 inch with all memory and turbo boost

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Any change?
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Why is my macbook air making such a loud noise?

I have a Macbook Air 13". I have just switched it on and the fans are making are considerably louder than usual. The laptop isn't hot at all, in fact from what I can feel it's blowing out quite cool air. Any ideas on why it is doing this and how to stop it?

Hello there, Carly.
It sounds like the fans on your MacBook Air are running at full speed after you've turned on your computer. The following Knowledge Base article offers a great recommendation for troubleshooting this issue:
iMac: Fans run at full speed after computer turns on - Apple Support
If you press the iMac power button while you are connecting the power cord, the iMac will enter a mode in which the fans run at full speed. In order to correct the issue, reset the SMC. Your iMac should now start up and operate as expected.
To avoid this issue, be sure to start the computer by pressing the power button after you fully connect the power cord.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Why is my macbook air not compatible with mountain lion?

When i want to buy montain lion in the app store i get the message that my machine (Macbook air) is not compatible. Why is that and can i do something to solve that problem?

Because your model is old and does not support the 64-bit EFI ROM requirement to install Mountain Lion. If you meet the 2 GB RAM requirements you could install Lion:
Upgrading to Snow Leopard, Lion, or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer)
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
         3. MacBook Pro (Mid/Late 2007 or newer)
         4. MacBook Air (Late 2008 or newer)
         5. Mac mini (Early 2009 or newer)
         6. Mac Pro (Early 2008 or newer)
         7. Xserve (Early 2009)
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
     Am I eligible for the free upgrade?
         See Apple - Free OS X Mountain Lion upgrade Program.
     For a complete How-To introduction from Apple see Upgrade to OS X Mountain Lion.

Why is my Macbook Air crashing?

Twice today I have come to my Macbook Air and both after both have been asleep for a while. When I wake it up it comes up with a folder with a question mark (?) inside it, blinking. I have done a temperary solve where I would just restart the computer and I would then work fine. I would like to know why it is doing this and how it can be fixed.
Thanks!

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

HT1237 Why does my MacBook Air (11-inch, Mid 2011) has the SMC version (1.74f3)?

According to the article (http://support.apple.com/kb/HT1237), the latest SMC version of MacBook Air should be 1.73f65 (SMC 1.6). However, I found the SMC version is 1.74f3, which should be MacBook Air (13-inch)'s.

Why cannot my macbook air read my external hard drive?

First of all, I have an external hard drive (Western Digital - WD5000H1U-00). I went to their website, downloaded the WD driver installer, and then installed the drivers. I even had restarted my MBA but when i plug the usb cable of my external hard drive, MBA can't read it. Why is that so? In my other computers, the external hard drive could be read.

It's probably formatted for Windows. Plug the hard drive into your MacBook Air. Open Disk Utility (User Name>Applications>Utilities). Go to the Partition tab. Select 1 under Volume Scheme and also click on options and choose GUID. Click Apply. That's it. But if you have any files on that drive, back it up because this option is going to erase your drive.

Why is my MacBook Air taking so long to connect to wi-fi at home and at work?

Why does my Macbook Air only have 64MB of dedicated video memory

Hello, I created a windows partition on my Macbook Air and after going into my Display settings I see that it only has 64MB of dedicated video memory out of 1696MB. Please tell me how I can fix this problem as I should have much more Dedicated memory from my Macbook air.
Additional INFO: MacBook Air Early 2014 edition, and has Intel 5000.

Hey thanks a lot for the quick reply Loner, however, I'm not really sure what you mean (sorry I'm a bit slow when it comes to computers). I checked out your link, and when I do the same steps as in the link by going into screen resolution> advanced> adapter: it shows Total Available Graphics Memory- 1696MB, and Dedicated Video Memory 64MB, but it only uses 64MB, it doesn't use more when it needs to.
I tried playing GTA 4 on my laptop via bootcamp, and in-game it tells me my laptop is only using 64MB of video memory and the game requires at least 260 or so, and my laptop won't use more (at least I'm pretty sure it is not using more or the game wouldn't give me that mssg).
Again, thanks for your response, and looking forward to what you have to say, or any other that want to chime in Thanks a lot as always.
