I have a MacBook Pro. Lately my volume button is grayed out and not working. Any solutions on how to fix this? Thanks.
I have an older MacBook Pro (circa 2009). Lately I've noticed my volume button is grayed out and I cannot adjust it. I've tried rebooting. Sometimes it becomes available to use and other times not. Any ideas on how to fix this? Thanks!
Reset the SMC. Check the Audio Midi Setup utility. If connected to an external display that has audio, that may have hijacked the audio.

Hey Guys i have a problem with my mac since last month and it wont boot up it freezes in a grey apple logo and and spinning gear any body know how to fix this?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Before reconnecting an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see above for instructions.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it produces. Look for the line "Permissions repaired successfully" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
Just connected apple tv. Everything works perfectly but the screen is not in color. I have tried reversing the HDMI cable and changing the output in settings and restarting. The screen is still black and white. Any ideas of how to fix this?
Hi im,
Thanks for using Apple Support Communities. This article has a few troubleshooting ideas for issues with color on your TV when using Apple TV:

Hello,
I have installed mountain lion on my macbook pro ,but it made my mac very slow. Would someone please tell me how to uninstall this one and reinstall snow leopard? I tried to do it by my original CDs but macbook pro didn't let me to do it.
ThanksIt would be easier to just fix whatever is making your machine slow.
I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

I have a MacBook Pro 5,4 running OSX 10.6.8 and Safari 5.1.10. A website i like has a known bug with 5.1.10 and recommends I install a newer version of Safari or use Firefox or Chrome. Just looking for advice on the best approach. Thanks!
Unfortunately, Safari cannot be updated past 5.1.10 on a Mac running v10.6.8.
So, the options are to upgrade to a newer OS X or use Firefox or Chrome.
Be aware, Apple no longer support Snow Leopard v10.6 > www.ibtimes.com/apple-kills-snow-leopard-os-x-106-no-longer-receives-security-u pdates-1558393
See if your Mac can run v10.9 Mavericks > OS X Mavericks: System Requirements
If so, you can download and install Mavericks for free from the App Store.

i have a macbook pro 15" retina Display with 2.6 ghz and 8gb of ram when i try to download an HD movie from itunes it says my computer doesn't support HD? i went to the support on the apple website and looked at the specs that a computer has to meet in order to play HD movies and mine is well above them. Why can't i play the movies?
That would at least partially explain it.
These MacBook Pros drew more power than the power brick could readily supply, and so would only run at top speed when the power brick was supplemented by the battery.
Though the applicable tech note has been removed, it stated:
"If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adapter alone can provide." -
Hello, I have a macbook pro retina-2013.
About Mavericks I could set my 4K monitor via HDMI on 2560x1440.
This I can not get through at Yosemite. Can someone help me there?They really pushed that it would all work great! Has anyone had the same struggle? Are there any step-by-step instructions to get linked up?
Call Verizon's wireless tech support & explain your problem to them. They will provide "step-by-step" instructions over the phone.
Take notes too!
TIP: If you do call & don't want to go through all those darn promps, when you initially call, just don't say anything. The automatic voice will then say, "will connect you to a service rep." -

So I have a MacBook Pro 2013. That won't turn on and won't charge.
So I have a MacBook Pro 2013. That won't turn on and won't charge. When the charger is plugged in the light remains green as if it is fully charge. Before it died the laptop still recognized the charger but wouldn't charge. And now won't turn on.
If you've a 2013 model, depending on when you purchased the machine, I would suppose that you're still under warranty or at least purchased AppleCare? Regardless, I would take the kit to your local Apple Store or an AASP and have them diagnose the computer (and, if you're still under warranty, fix the computer) and, if necessary, give you an estimate for repair.
There are all sorts of things that could be wrong - a faulty adapter, bad cabling, even the entire electrical circuitry may have gone bad.
You won't know unless you had an Apple tech look it over.
Good luck,
