My Macbook Pro sound setting always defaults to mute. How can I set the default to on?
Reset PRAM. http://support.apple.com/kb/PH4405
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".
Thanks, I tried both but the default is still mute.
