This is bordering on the comical.
To those who think no one uses this : Here is what Eric Persing of Spectrasonics , one of the leading developpers of pro virtual instruments in the audio world, and not exactly prone to tantrums, posted on his FB :
"APPLE HAS COMPLETELY LOST IT. I am absolutely FURIOUS about this news! This is literally a feature that our entire team at Spectrasonics utilizes EVERY DAY, dozens of times a day! The removal of optical out is INSANE! In our world of audio, this is a feature that made MacBook Pros truly a mobile/professional audio machine! Native core audio with simple digital audio output is one of the essential reasons that these laptops have always been the best for audio and music. NOW THEY'VE TAKEN IT AWAY SO THEY SAVE A PENNY!
I hate you apple! (Never thought I'd every say that)"
Whatever this machine is, it's certainly ain't pro.
