Macbook pro has no sound feedback after yosemite install
Got Yosemite installed and for some reason there was no sound when increasing/decreasing the volume through the keys or the slider. I tried to hear a youtube video but it was not working, I am using chrome so could see that there was sound on the video as there was an icon on the web page tab. I re-started and went to the system preferences>sound and found that by default in the general section, the sound feedback is disabled. I did not test the sound after the re-start so i dont know if there were two issues, but enabled the sound feedback and now I can hear the volume when moving the slider, also the music is playing fine through the internal speakers.
1. System Preference > Sound > Output
Internal Speakers selected?
2. Try 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".
3. If there is red light visible in the headphone port plug the head phone into and out of the port
couple of times to flip the microswitch inside. Sound may be stuck in digital mode.
4. Reinstalling iTunes may help sometimes.
Best.

Why is startup on my macbook pro extremely slow (3 minutes) after Yosemite install?
Prior to Yosemite upgrade, my mid-2010 Macbook pro (4 gb RAM) booted up fairly quickly (within 1 minute). After the Yosemite installation, boot time now is approximately 3 minutes. I have repaired disc permissions and that did not fix the problem. Any suggestions?
nothing seems out of order, apart from the useless Norton Internet Security.
though, since you don't have lots of RAM, consider rebooting the Mac everyso often ( "Time since boot: 7 days 3:2:21").
" Battery Health: Replace Now": indeed, the battery is dead
Did it start getting slow since Yosemite upgrade? (the new OS does tend to slow things down) -

What I can do to rescue my MacBook?If you enabled FileVault when you upgraded, it will take a few hours for the conversion process to finish, and during that time performance will be reduced. Otherwise see below.
Launch the Console 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 Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen. Click the Clear Display icon in the toolbar. Then take one of the actions that you're having trouble with. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.

0 B Page-outs1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in 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.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

MacBook Pro has no sound at all. Called Apple and they said to reinstall OS X.
I have recently discovered that my MacBook Pro has no sound except for the startup chime. I called Apple and they told me to reinstall OS X because something went wrong in the OS. Is there any other way to fix this?
That's a really overly simplistic answer to your problem. Re-installing OS X doesn't always fix every problem. Yes, it might in your case, but it might not. Are you still under warranty? Either way, I'd take it into your local Apple Store and show them the problem and let them fix it. If the system has to be installed anew, so be it. But rule out other problems first.
Before you do anything, make sure that you have a back-up of your data, applications, etc. If you don't already have a back-up scheme, get an external hard drive and use Time Machine to back up your computer. Then take it into the Apple Store.
Good luck,
Clinton -

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?
I get the impression that most of the users on older hardware experiences similar temperature issues on Lion for a long time now. Awaiting for confirmation from the original poster.
In the meantime I'm just cautious with regards to pushing the machine to such extreme temps, since something tells me such behaviour which includes monitor flickering and the likes is nothing but abnormal for any type of use...
Any clues if 10.7.5 does anything on this? If not I'm afraid i see myself going back to SL for good... -
My MacBook Pro has no sound, but the volume setting works
My 15' MacBook Pro 2012's sound is not working. You can still change the volume by pressing F10 to F12, but not actual sound comes out. The headphone jack is not red (although I have experienced that problem before and fixed it). Whether the headphones are plugged in or if they aren't, there is still no sound. I am running on OS X 10.7.5 with a 2.6 GHz Intel Core i7 Processor, 8GB 1600 MHz DDR3 Memory and the storage capacity is 749.3 GB total.
Have you tried a PRAM reset?

You inadvertently installed adware. Eradicating it is simple and you don't have to download or install anything to fix it. For an explanation or how this may have occurred, how to avoid it in the future, and for Apple's recommended solution read How to install adware.
Google Chrome is known to run notoriously poorly on Macs. If you want to run Google Chrome, you may need to install more memory, upgrade your Mac to a newer model, or both. Use Safari or Firefox, both of which will run well and do not litter a system with a plethora of resource - hungry "helpers" and other constantly running intrusive processes such as those Google insists upon installing.
Adobe Flash Player is outdated. If you need to use Adobe Flash Player, you must keep it up to date. New versions appear very frequently.
You are running a torrent client. Doing so will leave you vulnerable to malware, data theft, or both.
Some users have resolved otherwise inexplicably poor performance with an SMC reset. Read and follow all the steps including those that may appear to be inapplicable or trivial.
If your Mac still performs poorly, please determine if the same problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
If none of the above resolves your concern, more information is required. To augment the information you already provided, follow the instructions below.
If your Mac is momentarily unresponsive, consider the following.
Launch the Console app - it is in your Utilities folder. You can find it by selecting Utilities from the Finder's Go menu.
If the log list column on the left is not already displayed, show the log list by selecting Show Log List from Console's View menu. Select Show Toolbar if it is not already shown.
Locate system.log in the list and select it. Many date and time-stamped entries will appear, hundreds of them, and you must find the entries relevant to your Mac's problem.
To do that click the Clear Display button in the Toolbar. All previously displayed log entries will be disappear.
Next: Perform whatever actions cause the Mac to exhibit the slow behavior. If the problem is caused by errors logged by the system, the Console window will show them being recorded in system.log.
One or more of them, along with their time stamps, may reveal the reason for the problem you describe.
Copy and paste those log entries in a reply. If hundreds of the same repetitive messages appear, please edit them before posting. There should be no need for more than a few log entries.
Most of the entries will be cryptic but will contain information you might consider personal such as your Mac's name. If you do not want that information to appear, delete or obscure it when posting your reply. Leave enough information so that the entries can be deciphered. -
MacBook Pro will not boot up after Yosemite reinstall
I see that someone else has a similar problem but a potential responder asked A.N.Other with the same issue to start a new thread - hence this post.
I have a MacBook Pro, mid-2010 (I think) 500GB HD and maximum RAM. I installed Yosemite several months ago. The machine ran more slowly after installation. Eventually it reached a point where even typing a line of characters would set the beachball spinning. I removed seldom-used apps: there's about 25% free disk space. I ran Onyx on it, which I have used successfully over the years. I tried all the usual remedies e.g. verifying the disk (okay) and repairing permissions using Recovery Mode. Despite permissions being repaired a number of times, the same permissions - almost every one of which involved iTunes - continually recurred. I made a full back up. I switched the machine off then restarted it in Recovery Mode and used it to Reinstall Yosemite. It did take an age to download and then indicated that it was installing with "22 minutes remaining". That 22 minutes ran to several hours but I had seen this happen before, so just waited. It then went to the next step which is a restart - when the progress bar got to about 40% it slowed right down then stopped completely at about 50%.
I left it running overnight but the bar had not moved by the following day. I switched the machine off using the power button, then on again. The result was the same - freezing at about 50%. I have, since then, tried to start in Recovery Mode as well as Safe, Target, etc but there is simply no response to the keyboard commands - the logo and the progress bar appears, gets to 50% and freezes. When I did the full backup to an external HD I created a Recovery Partition on that: I have tried starting the machine without the HD plugged into the USB port and also with it plugged in - no difference, save that when it is plugged in the power light on the HD comes on, is static and then goes off.
I frankly have no idea what to try next. I need to access data on the machine or the backup pretty urgently: I am typing this request for assistance on a very old PowerBook G4 running OSX10.5.8 - at least THAT is reliable!
Any suggestions would be much appreciated - I live several hundred kilometres from the nearest Apple retail store and would like to avoid that trip if possible.I didn't try or allow it time to sleep in safe mode. Out of frustration, I decided to use recovery mode using time machine with my external HD and went back to the last setting before installing Yosemite. Seems to be working fine now without Yosemite. I guess I will wait til Yosemite is improved before upgrading to it.

I'm having a very strange thing happen on my Macbook Pro. When I turn on the macbook, I get the opening chime and then after that, there is no sound at all. When i increase the volume or decrease, the indicators go up and down, but still no sound. Can anyone explain what might be happening?
Was able to go to this posting and look at my system preferences and this seemed to do the trick. Seemed like after I used LogMeIn on my iPad, it set my audio to something else.

Macbook pro has no sound, any ideas on the cause?
My macbook pro crashed while watching a video and since then has not had any sound coming from the speakers, although it did emit the startup sound when I restarted it.
One of these steps may help.
1. System Preference > Sound > Output > Internal Speakers
Highlight Internal Speakers
Make sure that 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
Audio Devices window
Side Bar
Click the Built-in Output.
Under Mute any of the boxes checked? If so, uncheck it. -
My MacBook Pro has no sound, even with Apple headphones plugged in...
My Macbook Pro won't play any sound from both it's own speakers or any speaker I plug it into. This has me very worries, please help.

MacBook Pro has no sound, no way to adjust volume, and will not play music.
My MacBook Pro seems to have lost all of its audio functions. I cannot adjust my volume using the keyboard controls, or through the button at the top of my desktop screen, or even through System Preferences. I get the normal volume adjust screen, but it is faded, and there is a symbol over it indicating that I cannot adjust anything. When I go into the Sounds menu from System Preferences, there is nothing for me to select under Input or under Output. My computer makes no noise, whether I'm using iTunes, watching a video, or anything. I cannot play music. My songs simply won't start, and when I skip to any given part of a song, the music still refuses to play. I am not getting the red light from my headphone port. I tried to remove any dust that may have collected in the headphone port, and I've even tried to reset my NVRAM and PRAM. I also updated to OS X Mavericks 10.9.2. Nothing helped. I remember that my MacBook was working perfectly fine all of yesterday, but at one point later in the evening, I tried to plug in my headphones to play music, but nothing would play. I opened Spotify, and it gave me a message that my speakers were broken (I was using the internal speakers). That's when I first noticed the issue. Is there anything else I can try before going to the Apple Store and having them try to fix it? Thank you very much, I appreciate any help.
The last gasp is an OSX reinstall. If that fails, then the genius bar is the best option.

Macbook Pro won't boot OSX after Yosemite upgrade 10.10.3
I downloaded the update to 10.10.3 this morning before driving my daughter to daycare. When I came back, my Macbook Pro had rebooted into Windows 7 (Boot Camp). I restarted it by telling it to reboot to OSX, but it boots Windows again. If I turn it off completely, and then turn it on again, there's no chime... just a black screen for about 30 seconds, followed by "Starting Windows". I'm about to reboot to try resetting NVRAM and SMC, but I don't know if that's going to work without the chime...
I really need OSX to get going, so any help appreciated.If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.
