Headphones only play right side My Macbook pro OS X 10.8.5 headphone jack seems to work - like it knows when I plug in the headphones - but it only plays out of the right side. I've adjusted the balance in settings but the left side stays silent. I've tried many different headphones and its always the same. Any suggestions?
I own a Shure headset with 3 connectors and it does not work on my MacBook Pro Retina 15''late 2013 nor does it with my iPhone 4S --- only the channel marked with 'left' works. And even the 4 connector versions are different among the various Notebook/Phone manufacturers compared to Apple. There are special Apple compatible versions advertised. Best, Peter
