I feel like this article is FUD. Nearly every professional audio interface for Mac, iPhone, or iPad has a 1/4" stereo headphone output for real studio monitor headphones. No pro is concerned that they lost the 1/8" output for bargain headphones on their iPhone.
Any iMac or MacBook Pro from the last 5 years is sufficient for any pro audio workflow. A Mac Pro is still sufficient and is way overkill. A lot of people can be pretty productive on an iPad too. New Macs are coming, Apple isn't abandoning the Mac.
I just updated to macOS Sierra and all my pro audio equipment has either kept working as is or the manufacturer released a driver update within days of the macOS Sierra release.
