The cable is flimsy and cheap, and didn’t even work at all. When it arrived, it was clear that the price of the cable is about 3x what it should be. I cringed and made the purchase thinking it would be worth it if it solved my problem. I did some searching and originally purchased this Headset Buddy cable from Amazon. I guess it makes sense for Apple to standardize everything so you can use their headphones everywhere, but it caught me offguard and really frustrated me that I would have to buy something extra just to continue using my headset. I did some searching around, and discovered that Apple changed the standard dual input/output 3.5mm jacks for a single combined TRRS 3.5mm jack with 3 contacts – the same one they use for the iPod, iPhone, and iPad. I love it that Apple’s hardware is on the cutting edge, but sometimes they do things like this that just don’t make sense for the average user. I use a regularly use a gaming headset with a boom mic that was now rendered completely useless, because I was no longer able to plug in the mic. This is not a forum - please read the faq.One of the unexpected surprises that came with upgrading to a new Macbook Pro Retina 15″ from an older MacBook Pro was Apple’s inexplicable deletion of the audio input (mic) 3.5mm jack. If this answer helped you, please do not add a 'thank you' as another answer. That did the job, and I have internal sound again. I slid a paperclip in, and pushed out a little metal on the side. Plugging and unplugging the speakers may get it working right for awhile but it won't last forever. This disables the internal speakers and you see digital out instead of internal speakers in the speaker conrtol panel. The problem is when you remove the plug, the jack doesn't know it and keeps shining the red light to talk with the optical. The problem is there is a switch in the jack that tells it if you have a mini headphone plug or an optical plug plugged into the headphone port. There is a metal prong in the jack and sometimes it can be bent,Ĭausing the digital audio to be turned on when it shouldn't be. The red light is probably because its a Mini-TOSLINK port.
