I think when Steve Jobs was still alive, he enforced a philosophy at Apple that the Mac was the "cornerstone" of the company, no matter what else it developed. It was all about that "halo effect", where the Mac was the control center for everything else, and everything had a symbiotic relationship with everything else Apple sold. (EG. You could be a Windows user and buy an iPod as your music player, and use it just fine. BUT, you'd eventually say, "Hey... Apple's iTunes software that manages this thing really runs better on the Mac than it does in Windows. Maybe I'll just go with a Mac in the future and use it with this?" Or you might be a Windows or even Linux user who bought an Apple Airport Extreme as your wi-fi router because it got high reviews. You *could* manage it with the Windows version of the management software, but you'd find it's easier to just set one up from an iPhone, where support is built right in.)
Back then, it was commonplace for Jobs to remind people that low overall percentages of Mac sales compared to Windows didn't concern him. It was about selling gourmet food vs. McDonalds. If you have a premium product, you concentrate on catering to those who appreciate that ... not worrying about maximizing sales numbers.
Today, it's very different. Apple under Tim Cook seems to believe iOS devices are the "future" as the traditional computer dies out, and MANY of the complaints Mac users have are direct results of this change in course. There are problems right now with PDFKit in OS X, where Apple suddenly rewrote the thing from the ground up in OS X Sierra without so much as informing developers. The reason? They wanted one with feature parity with the iOS version. This made Apple's own Preview software unsafe to use to edit PDF documents, because it causes embedded OCR layers to be stripped from them when you save them. Other applications like Mariner Paperless, which use Preview to display scanned documents in their database, crash as soon as you try to view a file in your collection. It's basically a trainwreck right now. I hear Apple is scrambling to fix a lot of this in the latest OS X beta, but this fiasco already caused many realtors to switch back to Windows because they rely so heavily on PDF as part of their daily workflow,
If rumors I've heard can be believed, Apple doesn't even have much of a Mac OS X development team left anymore. The updates to it are supposedly being done by a team that's expected to spend part of their time doing iOS related work.
I've been a big Mac proponent since the 2001 time-frame, but I'm finally reaching the point where my next computer won't be a Mac, unless there's a major change of course in the near future. As others have said, Apple has nothing for sale that I'd really want to buy. The new Macbook Pro 15" looks desirable at first glance. The touch-bar is a nice addition and it looks attractive in space gray color and all that. But in reality, it's the most expensive laptop Apple has ever sold (in a high spec configuration at least), while demanding more compromises to use it than have ever been expected of "Pro" users before. The lack of all ports except USB-C would be more acceptable if the USB-C standard was more prevalent. But putting it there today is doing it just to prove you're "cutting edge", while hampering real-world usage. And at that price? Why isn't a set of the dongle adapters included with it?? The Mag-Safe charging was a mistake to eliminate too. That's been a signature feature that made Mac laptops a step ahead of everyone else. Couldn't they at least do a USB-C variant of Mag-Safe?
