I purchased a 3.5mm audio extender for my MacBook to have it closer in case I have to plug in my headphones. The problem is that when I plug in the extender (without the headphones) the Mac thinks I have my headphones are plugged in. Is there any way around this? I want to have my speakers as the output when the extender is plugged in, and the headphones when I plug in my headphones in the extender. Thanks!
