Now the latest version is macOS High Sierra. To check that, click Software Update in the About this Mac window. If there is, install it. Before you install either a new version of the OS or an update, backup your Mac using Time Machine , or whichever backup tool you normally use. These optimize the performance of your Mac by running a number of routines such as repairing disk permissions, verifying your startup disk, and rebuilding the launch services database. The best thing to do in that instance is to uninstall the app.
To do that, you should use a dedicated uninstaller like CleanMyMac X. You can download CleanMyMac for free here. The most common occurrence of this problem is on pre Macs that had a digital audio output support in the headphone jack. On those Macs, there was a sensor in the port that detected whether a headphone jack or a digital audio device was plugged in.
What to do if the sound is not working on your Mac
The Mac would then change the output to headphones or digital output accordingly. However, sometimes the sensor failed to recognise when a digital audio device had been unplugged and so the audio output remained locked on digital output, with no way to change it.
With no digital audio output connected, there is no way to change the volume or hear sound. The solution in that case is to plug the cable back in to the socket and remove it again.

Try blowing on it to remove any dust. Put the swab into the headphone jack and clean it, wiping away as much of the link as possible. Your Mac can play audio wirelessly via Bluetooth, so if you have Bluetooth speakers or headphones, you can use those to listen to music, or anything else on your Mac. If you check the box labelled Show Bluetooth in menu bar in Bluetooth preferences, you can connect from the menu bar item.
I have a MBPR 15inch, 1st version.
Oh my god, thank you so much! However, this did! After trying just about everything I came across a tip to apply high pressure air-duster to the port.
Get help if the internal speakers on your Mac don't make sound
That solved the issue! Apperantly dust might cause the sound to be routed to an optical channel, causing the hiccups. What can I do to fix this issue? I came across this thread upon finding that my internal speakers would not show up as an option after I had used an external speaker for amplification. The Sound Preferences would keep looking for the external speakers even after they were disconnected. Using MacBook running Clearly a software bug. My mac book pro used to automatically select the audio output.
If I plugged my headphones in, they would mute the speakers and the sound would only come through the headphones. I have an apple display and when it was connected if would automatically know to play audio out of the display. Now, I have to manually select it from system preferences or for the menu bar.
Can someone help me figure out if I can get it back to automatic? Hello, I have tried this but nothing is seeming to appear in my output or input box? Maybe the internal contacts are dirty or gummed up a bit.

User error, works for everyone but you. Jokes on you Cruz! Maybe you should read the instructions to fix the audio working in your Mac.
I never had this problem with OS9. Nor with The only solution is to reboot. Since I am not interested in quick fixes, but prefer a permanent fix, is the only option then switch to Microsoft 10? What if there is no internal speakers option. Reset pram, turned off bluetooth, rebooted, no red light coming out if any ports. This fix totally worked for me! Thank you! I was getting ready to visit an authorized apple dealer to fix the problem.
Reinstalled latest OS update Go figure…. Even when I do this my sound still does not work whether I have earbuds or nots, can anyone help me? Called to Apple support: You can do this at the command line as well.

See https: Thank God I found this article before I took it to the service center. Eerily, it happened just after I dropped my mac! Thanks a ton! Open to ActivityMonitor, list all process and search coreaudiod select and force quit. Problem solved: Hear a bump sound and audio is back!?
