My Macbook Pro has recently started to mute/unmute itself randomly. VERY FRUSTRATING! It doesn't matter whether I have speakers connected or using the onboard speakers. Any suggestions?

My Macbook Pro has recently started to mute/unmute itself randomly. VERY FRUSTRATING! It doesn't matter whether I have speakers connected or using the onboard speakers. Any suggestions?
I have looked at other forums and the fixes suggested do NOT work.
What would cause this?
How is it corrected?

Hello DChrystal
Try paying attention to the Keyboard Viewer to see if any keys are being pressed that could be causing the sound to be muted. If it is, try it in another user to see if it is software that is causing the issue or if it is the actual keyboard that is having the issue.
One or more keys on the keyboard do not respond

MacBook Pro has recently started to crash.

My MacBook Pro has recently started to crash. It sometimes crashes when watching streamed video (youtube/netflix), and will always crash when using high processor programs (e.g. final cut X, Logic Pro) and cannot run any games without crashing. Usually starts running hot before cutting to a blank screen (and any audio starts to loop), and requires a hard reboot.
Any help would be apreciated.
below are the latest error report, and hardware copied from settings.

You probably have the issue addressed by that article.
Take the computer to Apple or an authorised repairer, tell them that you think it may be the problem mentioned, and they should run a simple pass/fail test.
The service is only for three years after initial purchase, but several users here have reported getting free repairs even after that limit, sometimes after contacting Apple customer relations, pr speaking to an Apple store manager.

My MacBook Pro has been having difficulties at startup. It sometimes locks and doesn't get past the white screen. It has also locked up several times and gotten a green stripes across the entire screen. What is causing this and how do I fix it?

You don't, take it to Apple for repair.
This might interest you if it's too old to fix.

It was running fine until the last couple months when my microsoft office started to act a bit weird. But the speed was still fine until the last few weeks.
I don't very often turn off my mac which I've read to be a problem and that it should be switched off every now and then.
I also have repaired my startup HD and also cleared my disk spaces as suggested.
I've also tried the PRAM option and the OnyX option to give the computer a clean up and maintenance.
So when i first start up the macbook pro it would run ok with most of the applications i have. I check the CPU usage and its all Ok.
The one thing that takes up all of my CPU usage % is my safari web content. When i watch something on any site or on youtube, the whole macbookpro becomes really slow as all my RAM gets used up by the safari and safari web content. I've never realised how much it is meant to use up but I dont think it is meant to use up that much.
So then after watching something on youtube and such the macbook pro becomes extremely slow and sluggish and will need a restart to run normally
Can I please have some suggestions on what is wrong and how to fix it?
Any help would be greatly appreiated!

From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.

My MacBook Pro has downloaded my old emails twice into my Outlook folder. Why? How do I stop this from recalling all the old emails?

My MacBook Pro has downloaded all my previous emails (several months worth) and reloaded them into my Inbox twice! Why is this happening? How do I get it to stop from happening again?
Thanks!

Since this is an Outlook question, you should ask over on the Microsoft Office for Mac forums.

Hello! My MacBook Pro has suddenly started running slow.

Hello!
     I've had my MacBook Pro for since 2011 and it has suddenly started running slow. This has been going on for a month. I've restarted my MacBook several times and even shut it down when I know I will not be using for the remainder of the day. I've tried numerous things to make it run faster including deleting useless files like text documents, pictures, videos, etc. I currently have 92.67GB free of 500GB . I've noticed that when it gets hot it starts running slow or when I play a video game and sometimes when I play videos online.

Macbook Pro has slow start up after Time Machine restore

My 2.4 Ghz Santa Rosa MBP had Ubuntu Hardy and 10.5 on it. I played with Ubuntu for a while and decided to go back to OS X only. I wiped the HDD and reinstalled Leopard, then restored from a time machine back-up. Since then, my MBP has gone to a white blank screen for about 5 or 6 seconds before displaying an apple on start up. What could be causing this? I tried disk utility options, nothing worked, restored from a different back- up with no luck also. Any Ideas? My start up has slowed a very noticeable amount since going back to one OS
Thanks in Advance

This is the MacBook forum, not the MacBook Pro forum.

My MacBook Air has recently started having substantial WiFi connectivity issues. How do I fix this?

For the last couple weeks my MacBook Air has started having some mighty substantial connectivity issues.
When I wake it from sleep, or if I'm using it for an extended period (say, more than 5-10 minutes), the connection will become extremely unreliable. This primarily happens with browsers, or the Twitter application. For example, if I start a call on Skype the call will continue to function just fine, but I won't be able to connect to any websites through any browser. I've tried Safari, Chrome, and Firefox while the connectivity problems are occuring. When they do occur, a full shut down and cold boot are required to make it work again for a short while.
Does anyone know what might be causing this? I've done numerous checks for malware using Clam Xav and Sophos Anti-Virus. (I didn't suspect that this would be the issue, but it was still something that I decided to rule out.) Additionally, I've tried connecting using both the 2.4GHz and 5GHz bands on my wireless router. Neither seems to be more successful than the other. (Note: The 5GHz works perfectly and without interruption on my iPad and desktop PC. The 2.4GHz works perfectly with my iPhone 4S and Xbox 360. I feel that with that in mind, I can safely rule out the router as the root of the problem. Both of these examples go on for very extended periods of time. I game regularly using both my PC and Xbox 360.)

Hi Jollified,
Does your sound work when you try to use head/earphones? If so, try the following:
Plug your Headphones into your Mac.
Play a sound through them (a song for example), then stop the sound.
Make sure 'Preferences' is isn't open. If it is, Quit.
Launch System Preferences > Sounds.
While the Sounds tab is open and set to 'Headphones', pull out the Headphones from the jack.
You should see your Mac reset to 'Internal Speakers'
Also, I see you have tried resetting the PRAM, have you tried resetting the System Management Controller (SMC)? Resetting the System Management Controller (SMC) on your Mac - Apple Support
As for your MacBook not sleeping when you close the lid, there are many reasons this can occur.
First of all, check out Apples article on the issue: OS X Yosemite: If your Mac won’t go to or stay in sleep If you find these steps don't help, try a few of the following:
A common cause for the Mac not sleeping is your printer. If there are queued jobs waiting to be printed, but your printer is switched off, for some reason you Mac just wont like it and simply will not go to sleep. System Preferences > Print and Scan > Open Print Queue
Do you have an Ethernet Cable connected? People have reported in the past that removing their Ethernet allowed their Mac to sleep. This goes for other things you may have connected directly to your Mac also.
Try heading into your Mac Preferences > Sharing and deselecting 'Internet Sharing' as well as 'Printer Sharing'.
Also deselect Wake For Network Access by heading to System Preferences > Energy Saver > Power Adapter > Wake For Network Access.
Energy Saver > Schedule > Startup or Wake - Uncheck.
Alternatively, set your system preferences to Never Sleep, and put into Sleep manually: System Preferences > Energy Saver > Computer Sleep > Never.
Good luck!

My MacBook Pro was recently stolen, is it possible to more or less "shut down" that laptop if I have the serial number?

my macbook was recently stolen, is it possible to more or less "shut down" that computer if i have the serial number?

Welcome to Apple Support Communities
First, report this to the police. Then, you can't do anything with your serial number to track the MacBook.
Instead, if you turned on Find my Mac, you can track it if it's connected to Internet. You can track it with the Find my iPhone app from any iPhone, iPad or iPod touch, or from http://www.icloud.com at any Mac or PC.
If you didn't turn on Find my Mac, there's not anything else you can do apart from reporting that to the police

Re: My MacBook Pro has a fan that runs constantly and is very hot!

I have a MacBook Pro 17" from around 2010. I had the same thing with the constantly running fan. I reset the SMC and the PRAM which didn't help. Then I switched from using Google Chrome back to Safari and it seems to have returned to normal. Maybe there is an issue with Google Chrome?

There are many issues with Google Chrome.

If your Mac Pro has recently started buzzing, read this!

My Mac Pro started buzzing a couple of days ago. It was an extremely annoying buzz that was rather loud but also intermittent. I've owned the machine for about a month now, and wondered whether something in the computer was failing, such as the power supply, which was where the buzz seemed to be originating from.
As it turns out, over time, the ribbon cable leading to my optical drive worked its way against the fan on the power supply. Whenever the fan on the power supply ramped up, the unit would vibrate against the ribbon cable, causing the buzzing sound. A couple of pieces of tape fixed it the problem.

I had exactly the same problem with my Mac Pro - but identified it as Bay 2. Pressing on the side of the case stopped the buzzing, but as soon as i let go it started again. I just reseated the drive and so far the buzzing hasn't returned
I had a deeper buzzing sound, lower than what a
fan/ribbon cable would bake. I pinpointed it to
drive bay 1. If I applied pressure to the fascia of
the drive sled, the noise subsided, push too hard and
it came back. I moved the drive to bay 3 and put
that drive ni bay 1. The noise is gone. Seems that
those sleds vibrate if they do not have the exact
amount of pressure.

I have a MacBook Pro, it recently started freezing upon startup. It would get to a blue screen and just sit there. I've tried booting in safemode to run disk repair and still doesnt help. If I do manage to get past the blue screen, it still freezes

My mac keeps freezing upon startup. It will get to the blue screen and promptly freeze. If I manage to get past the blue screen, and open up youtube on google chrome, it will freeze before it loads youtube. I've tried safeboot and disk repair, nothing seems to work. I even tried to factory reset it but it wont connect to my internet when I reboot with power + option.. any ideas?

This can be used to boot the machine and delelte enough files to get it to boot normally.
.Create a data recovery/undelete external boot drive
Read about storage drive so you can store your extra stuff.
Most commonly used backup methods
Also here to see how a full boot drive slows the machine down
Why is my computer slow?

My MacBook Pro has just started getting really warm for no apparent reason, any ideas why?

Should I use my Apple Care, or is there a quick fix?

you see what is running on your computer (because CPU usage is what makes the procesor(s) get hot) by opening the application "Activity Monitor" in the folder "/Applications/Utilities", then select the "CPU" tab (at the bottom) and sort the information in the top section by "%CPU":
This will show you what application is using the most CPU time and is the most likely candidate for why your machine is warming up. You can also quit all applications, then reboot to see if that resolves the problem.

Macbook Pro can only start up in safe mode

Hi,
My Macbook Pro has recently been freezing on a blue screen when I try and start up. I seem to only be able to start up in safe mode.
I have followed some instructions found regarding the blue screen issue: deleting some files out of library/startupitems folder
and managed to start up normally once, then soon after I got a message saying I need to restart my computer by holding down the power button.
I am now back to having to log in using safe mode.
Does anyone know how I can fix this?

MacBook Pro will not start after removing battery?

My MacBook Pro has recently had a brand new battery put it, it's worked perfectly till now. My mouse was very loose so I decided to tighten it up. So I removed the battery, tightened the mouse and replaced the battery back (I've checked it's right) . However it now won't start up! At all, even when plugged into the mains. A faint flicking green light comes on the charger. Please help!

good luck.....if all else fails, bring it to Apple and see what's going on with it. Just don't let them know that you took the battery out.

My Macbook Pro has recently started to mute/unmute itself randomly. VERY FRUSTRATING! It doesn't matter whether I have speakers connected or using the onboard speakers. Any suggestions?
