Have you lost control of your keyboard volume keys on your Macintosh, especially since upgrading to Mac OS X El Capitan? You’re not alone. Here’s a few things to try if you suddenly cannot control your volume keys on your MacBook, MacBook Pro, iMac or any other Macintosh computer.
First, make sure you aren’t running the TIDAL music player software–this seems to be a common thread for the Macintosh keyboard volume keys not working. TIDAL is a streaming music service that has a corresponding software component that can cause the Mac volume keys to simply stop working. To test this theory, simply quit the TIDAL application on the Mac and see if your volume keys begin to work. If this is the case, simply stop using the TIDAL application to have your Mac volume buttons back to normal.
Another trick to try when you cannot get the volume keys on the Mac to work is to check inside of the system preferences. Locate the Keyboard system preference and note the status of the checkbox that says “Use all F1, F2, etc. as function keys.” If this box is checked, try unchecking it to return the Mac volume keys to normal working order. If the box is checked, this could be causing your Mac OS X volume keys not to work.
Lastly, make sure you don’t have the Google Music extension in Chrome running on your Mac, which could be hijacking all of your media keys, including the iTunes software. By removing this extension, you may fix the volume key issue on your Mac.
