The real problem is people aren't buying desktops like they used to, and as a percentage of Apple's revenue they're almost non-existent. They're in a bit of a bind here. They can't cater to every niche need, they're not going to make these quirky, narrow-use spec machines. They can't compete on price compared to hand-built. They can't compete on performance compared to the ultra-high end workstations from other vendors. Maybe if they opened up a limited licensing program for macOS on desktop machines to a handful of premium vendors that are willing to adhere to certain constraints they'd have a way out of this jam.
