Apple appears to have removed optical audio output support from the headphone jack on its new 13-inch MacBook Pro with function keys, suggesting it is unlikely to have made the transition in the Touch Bar equipped models either.

Optical audio output is used to link Macs to home theater setups and A/V systems capable of multi-channel surround sound, by way of a mini TOSlink adapter connected to the 3.5mm jack.

The removal of optical audio was first noted by AppleInsider, after it was discovered that Apple's technical specifications for the headphone jack no longer mentions support for "audio line out (digital/analog)".

Removal of the standard was confirmed by comparing the System Profiler report on a new 13-inch MacBook Pro, which makes no mention of S/PDIF Optical Digital Audio Output, against reports on 2015 models, which do.

When queried about the removal, Apple said the feature was dropped due to a lack of customers using the functionality, noting that "plenty of USB-C zero-latency professional peripherals are available now, or coming very soon" with optical audio out connectivity.

The phasing out of the standard from the new MacBook Pro models follows a trend that began with the Apple TV. Apple ditched the optical audio port on the fourth generation Apple TV in favor of a USB-C port, preventing users from connecting headphones directly to the device.

Be less mad at Apple and be mad at the industry that has more or less universally discarded the standard. TOSlink is hardly on anything being made any more.

As an owner of 5.1 wireless headphones that rely on TOSlink to work, let me point you im the direction of a Tendak TOSlink breakout box for HDMI.

Tendak 4K x 2K HDMI to HDMI and Optical TOSLINK SPDIF + 3.5mm Stereo Audio Extractor Converter HDMI Audio Splitter Adapter(HDMI Input, HDMI + Digital / Analog Audio Output) https://www.amazon.com/dp/B017B6WFP8/ref=cm_sw_r_cp_tai_aKghyb5RQR9PY

Put this wherever your sound system is, along with an HDMI to USB-c connector, and you can continue using optical audio receivers without an issue.

I'm with Apple on this one. I wonder how many people used this feature on the previous gen. Just because it's there doesn't mean it's useful. If you call yourself a "pro" you're probably using something else for your digital I/O needs.
 
I hope this product fails so bad Apple wants to cut the price in half. I guess it is too expensive for me given all the negative sides to buy one, I guess.
I hope Apple cuts the price in half also. Because I'm selfish. I hope they include all the adapters I personally need, for free (but not any that I don't need, because that would be wasteful).
