Upgraded to Yosemite 10.10.2 - no sound

I just upgraded to OS X Yosemite 10.10.2 and am not receiving any sound via headphones or speakers.
My output is set to headphones, input is set to External Microphone.
Please advise how to fix this.

Remove "Soundflower" and see whether there's a change.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time. Its completely random and i already checked all apps in use and its not from them.

Sounds like Notifications app.
Maybe some other app. In SystemPreferences->Users&Groups->LoginItems tab: remove all entries with the minus sign underneath. This will not uninstall anything, you have to start those apps by hand now. Restart.
Still there?
Yes: Restart again while holding the shift key, this will start the mac in SafeMode: only the necessary items are loaded to run.
Still there?
Yes: Make an etrecheck list and post it here.
No: Restart, put the items in the LoginItems back, one by one, restart after each entry, and you will find the "culprit"
Please report accordingly. I will be back in 24 hours.

No Sound, Safari Slow & MacBook Pro Very Slow after upgrading to Yosemite.

Hi All,
Upgrading to Yosemite has resulted in the following issues with my computer/laptop:
1. I have lost all sound and the sound options are no longer there after looking in Preferences.
2. Safari only loads parts of pages and then takes forever to load the rest.
3. Generally the computer has been slow with processes taking over the CPU and there seems to be a lot of hard memory swaps.
Attached is the EtreCheck.    Any help would be appreciated.   It appears that I also am missing some daemons that are launching.

How do I get sound to work on my early 2009 iMac after upgrading to Yosemite?

The sound on my early 2009 iMac has stopped working after upgrading to Yosemite from 10.6.8.
It still makes sound when I boot it up, so I don't think this is a hardware issue.

Hi qhaine,
Thanks for the question. After reviewing your post, it sounds like you are having trouble hearing sound from the iMac speakers. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

Thanks for using Apple Support Communities.
Have a nice day,

After upgrading on Yosemite my MacBook experiences sound problems

Hi, everyone.
I have a MacBook Pro 13 with Retina Display, late 2012.
After I upgraded to Yosemite I faced a problem regarding to my speakers.
When I start to work with my Mac after it was sleeping for a few hours (after a night, for example), I simply can't control the volume of sound.
In other words, when I use F10-F12 buttons to regulate the sound, my Mac shows me a crossed circle, as I don't have speakers at all.
And the only thing helps me (except rebooting) is go to settings -> Sound -> Output volume and scroll the volume bar manually.
After these actions, the speakers are in control with buttons as well.
That is annoying and I duno how to fix it except reinstalling OSX.
The other fact I was upgrading to Yosemite from Mavericks.
Any suggestions?

Hi shenya,
Welcome to the Apple Support Communities!
I know issues with sound can be very frustrating and it sounds like you have done some great troubleshooting already. In this situation I would recommend resetting the PRAM on your MacBook Pro. Please use the attached article for information on completing this process.
OS X Yosemite: Reset your computer’s PRAM
Best regards,

Sound problem after upgrading to Yosemite.

After upgrading to Yosemite, Sound driver suddenly stopped working as you see in the image.

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do notappear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

Why can't my mid2009 mac book pro upgrade to Yosemite? It sounds like Apple is using a page from microsoft to be a new computer....

I am trying to understand why Apple is not allowing mid2009 macbook pro's to upgrade to yosemite. What else is Apple not going to support? It looks like Apple had taken a page from the microsoft book. This is really frustrating.

Let me give you a slightly different perspective than everyone else here. You are using an unsecured wireless network, which means that all your network traffic is easily available for viewing by anyone else using that network. That's bad. Very bad, for you, unless you absolutely trust everyone who lives within range of this network. So stop doing it.
As to the Mac not connecting, wireless networking is simply too complex for any reasonable answer without more information. There are many possible error points, and as often as not it's the Mac that can connect and the Windows PC that cannot. Since you can't give us any information about the configuration of the neighbor's network, and can't make any changes to it, we can't do much to help you troubleshoot it.

Upgraded to yosemite now my speakers don't work and i can't play videos on Facebook.

When i play a video on face book I'm told i need to upgrade flashplayer, i wasn't even aware i had it downloaded! I have got rid of flash player (i think ) and now I'm told i need to download FP before i can watch videos. I can't play games on FB either and my speakers don't work.
I wish i hadn't upgraded to Yosemite to be honest as i prefer the old layout and it seems to have caused me problems. Everything was working fine before the Upgrade to Yosemite.
Im not good with computer terminology so please reply as simply as possible :-)
Thank you

Try un-installing and then re-installing.

Black boot screen and startup manager on mid 2014 rMBP after upgrading to Yosemite

After upgrading to Yosemite I'm experiencing black booting process. Moreover, I noticed that the startup manager, which we access by holding the option key, has the black background too. I didn't like the Yosemite, so I downgraded back to Mavericks, but I still have the startup manager with the black background and the initial screen during the startup sound is black too, and after that the grey screen with the Apple logo comes up, which is typical for Mavericks. I want my startup manager to have the grey background as before. And also, before there was the grey screen during the startup sound, not the black one. How to revert all this to the previous state? I'm experiencing all this on my rMBP, 13-inch, mid-2014.
I want to revert because after downgrading back to Mavericks my rMBP started freezing terribly, especially on youtube, ebay and app store. And it's not just the web browsing, it's freezing when navigating in finder too. I know there are many experienced users here, so I hope that somebody can help me with this. Before upgrading to Yosemite my machine was running flawlessly.

How do I update GarageBand after upgrading to Yosemite 10.10.1

I have GarageBand on my MacBook Pro but have recently upgraded to Yosemite OS X 10.10.2. I wanted to use GarageBand but rec'd a message that there is a newer version. I didn't think I should have to pay for an upgrade in the App Store. How do I update my version of GarageBand?

Which version of GarageBand do you currently have?
Updates are free (when the first number of the version number stays the same), but upgrades to a major new release require a purchase (when the first part of the version number changes). So the upgrade from GarageBand '11, version 6.0.5 to GarageBand 10.0.3 is a major upgrade, that requires a purchase.
If you decide to upgrade, do not replace your current GarageBand version, if you are currently running GarageBand 6.0.5. Keep both versions. The new GarageBand is very different from version 6.0.5 - it is more like Logic than GarageBand. It comes with nice new features like smart drummers, but but older audio units are no longer support. If you decide to upgrade your system, keep your current GarageBand as well. Both can be used in parallel and you will need the sounds and loops from the previous version to play your older projects. This forum is full of desperate questions about how to get the previous version back, because instruments are missing or podcasts no longer supported.

After upgrading to Yosemite I cannot see my other iMac at home (note I am at work) in the Finder window shared devices. Note my iMac at home is connected to an airport extreme (as is my work iMac) and I can see both airport extreme.

Aftger I upgraded to Yosemite I cannot see my iMac at home from my work (i.e in Finder window under shared devices). Note both my work and home iMac are connected to time capsules and I can see both of those time capsules but I cannot see either iMac from the other location. My guess is that the time capsule is blocking the connection to the iMac. One last comment occasionally (5% of the time) my iMac does magically appear in the shared Finder window but this is extremely rare. Any help????

Just discovered this one myself. OK, this may sound silly but place your cursor next to the word "Shared" on the finder sidebar. The "hidden" command "Show" will magically appear. Clicking that will display your other network attached devices.
This appears to be a new "feature" that some freaking genius thought was some how "Cool". My only assumption is that Apple programers expect users to randomly move their cursor around the screen in hopes of finding some critical function like looking for an easter egg in their favorite game.

Reset 10.5.8 then upgrade to Yosemite - buying least amount of disks

I am helping a friend out with her Macbook and need some advice. It is having problems and I'd like to reset it to factory settings but she does not have the disks. I am aware that I could create a new user, but since it is also having problems, she'd like to start fresh. The laptop is currently running 10.5.8 so I cannot reset by rebooting in recovery. I understand that I could buy the retail Leopard disks and use those to reboot, but after the reset, we plan to purchase Snow Leopard then upgrade to Yosemite.
I am not as familiar with Mac as I am with PCs and I have a few questions. Can she just buy the retail disks for Snow Leopard then reset to factory settings using that or does she first have to reset using Leopard disks? The laptop is a Macbook Late 2008 model, identifier 5,1. It's a 2.4 GHz with 2GB of RAM and a 250 GB SATA. It could use some extra RAM but other than that, it sounds like it will run Yosemite pretty well.
What advice or recommendations do you have for 1) resetting then upgrading to the most recent OS version, and 2) while buying the least amount of disks/OS versions? On a side note, the battery is not charging so I will need to go into Apple and get that replaced. Do you think that they would reset and upgrade me there?
Thank you for the help!!

Upgrading to Snow Leopard
You can 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 Mavericks 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 iCloud services; fees and
           terms apply.
Then to perform a clean erase and install of Snow Leopard:
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. After you finish Setup Assistant will complete the installation after which
         you will be running a fresh install of OS X. You can now begin the update process
         by opening Software Update and installing all recommended updates to bring your
         installation current.
     5. If you are planning to sell or give your computer away, then do the following:
        After you reformat your hard drive and reinstall OS X, the computer restarts to a
        Welcome screen and asks you to choose a country or region. If you want to leave
        the Mac in an out-of-box state, don't continue with the setup of your system. Instead,
        press Command-Q to shut down the Mac. When the new owner turns on the Mac,
        the Setup Assistant will guide them through the setup process.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Headphone jack is not working after upgrade to yosemite

My headphone jack was perfectly ok till i was using Mavericks. However as soon as i upgraded to Yosemite the headphone jack stops working. I am not 100% sure that the software update has caused the issue but it is likely.

I had the same problem and chatted with tech support and they told me to reset the PRAM and SMC which did not fix the issue. After contacting them a second time I was told my computer needs to be repaired. Which is not the problem it is a software issue.
What finally fixed it was (this was done after resetting the PRAM and SMC):
* Note: you can try this first and maybe it will solve your issue if not reset the PRAM and SMC then do the following.
1. Open system preferences
2. Chose sound
3. Chose Output then headphones
4. With headphones plugged in I checked the mute box on the bottom right and unchecked it they worked.
Then when unplugged the speakers didn't work so I did the same but choosing the internal speakers
OS X Mavericks: Reset your computer’s PRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Hope this helps others!!
