I write Mac software for a YC company in the pro video space. Our new product started deployments a couple of months back, and a major source of problems has been the Apple platform -- both hardware and software. It's so bad that we're actively working to move off the Mac completely. (I've spent 15 years doing Mac software, so this is a big deal for me.)
Apple doesn't have pro hardware anymore. The 2013 Mac Pro is a complete failure, maybe the worst computer they've ever made. We deployed a dozen Mac Pros, and four of them suffer from a GPU overheating problem that's widespread but little talked about -- Apple has been replacing Mac Pros quietly for years.
The original Mac Pro was a great computer for the pro market: lots of extensibility, high-quality cooling system. The new Mac Pro removed all that and offers no benefit to users like us. It's really more like a cylindrical rebirth of the infamous Power Mac G4 Cube.
The same heat problems apply to their laptops. Many MBP models with NVIDIA graphics end up needing yearly motherboard replacements, which Apple is providing through a special replacement program. (My previous MacBook Pro has had this done three times.) Apple's drive towards ever-thinner and ideally fanless computers like the 12" MacBook suggests that this trend isn't going to change. I'm afraid the next MacBook Pro will be the "worst of both worlds", a combination of traits from the 12" MacBook and the Mac Pro.
Meanwhile on the software front, macOS has become an unstable and unpredictable platform for high-performance media applications. The emphasis on power saving, sandboxing and relentlessly throttling down userspace applications has made it quite hard to ensure that all our processes keep ticking along as they should. Working around macOS features designed for fanless laptops is such a waste of time when our deployment environment would ideally be a rackmount old-style Mac Pro.
Looks like there's going to be lots of Windows 10 in my future :(
