So he's a developer, work that doesn't require the power of a workstation.

While that's true for some is much less true for pros. You probably ad never to work with pro video hardware. Some equipment has the ugliest look but is very functionals and gets the job done. In the end when you have deadlines, with a work to produce and deliver, the top priority is to get things done an possibly do so on schedule and with the least road bumps. The look of the equipment used is a nice to have, but most definitely not a must. What's most important to some is to be able to work on the same machine without having to jump on a PC workstation to work on post and go back to a mac to work on the soundtrack for instance. With the new trashcan form factor, Apple de-facto abandoned the pro market and gave a massive middle finger to all who trusted Apple and heavily invested in their platform and compatible equipment. If Apple wanted to show they were still able to innovate (one of the things boasted by Phil Schiller), could've done an anniversary edition as a collector's build with limited run. If they gave half a flying about pro customers would have stayed away from the shiny trashcan and continue improve and innovate the great design they already had in their line of professional workstations. Pros could care less about the claims of packing so much power in such a small space, pro studios have plenty space dedicated to work and don't need to fit a workstation on the compact ikea desk next to the sofa bed in the 50 square feet room in the shared apartment. Pro does not belong in the name of this model no matter how much power its claimed to have... plus it has seen no further improvements since its launch back in 2013. If that's not lame I don't know what would be.

I had problems (crashes) with Yosemite, but since I upgraded to Capitan (almost a year ago) I had no more problems and everything runs smooth as butter.

I have used hackintosh many times with 0 issues, but others like yourself have bugs and crashing issues. So no, its not perfect. But if you need a high power computer and the mac pro isn't handling your needs, its the only option. :(

Couldn't agree more. Not to mention that no respectable pro would chose to rely on an hackintosh for mission critical production as such machines could be "time bombs" which might fail you right when you need them the most, like in the middle of delivering a project! And missing a deadline might cost you money, reputation and possibly future jobs. So no hackintosh might be interesting and viable for personal non-critical use, most definitely not a viable choice for serious professionals.

Agreed, tools I need are generally mac OS only. Except video editing, which is cross platform for me (adobe)

So, I agree that apple needs to make a better pro computer, but In my experience, hackintosh works really really well. But I understand the need for endorsements and apple care and... honestly support if something goes wrong, hackintosh is kind of hit and miss.

It’s a shame Apple seems to be marching steadily away from that.

How else are they going to make money if they don't lock you in their hardware system? They're certainly not producing anything else to make much money these days. It's their survival tactic to keep business profit high for the last 5 years and the foreseeable future.
