After I installed Yosemite, my volume control keys would not work. Instead of doing their job, they switch the screen to a different view.
MacBook, OS X Yosemite (10.10.5)
Greetings jmh8,
Thanks for visiting Apple Support Communities.
It appears that pressing the volume control keys on your MacBook keyboard have different functions after updating to OS X Yosemite.
Most likely the "Use all F1, F2, etc. keys as standard function keys" setting has been enabled, and F11 and F12 are triggering Mission Control features. You can disable (un-check) this setting by going to Apple menu > System Preferences > Keyboard.
For more information on these features, see How to change the behavior of function keys on your Mac and OS X Yosemite: Mission Control preferences.
Happy Computing.
