OK, thanks, that's pretty much how I was seeing it too. I saw the changes listed and that's really why I asked the question. Like others, I believe the Hackintosh is as good as dead, and the upgrades since 10.14.2 seem to me to have very limited benefit, even setting on one side the Facetime changes and emoji additions, both of which I have problems taking seriously. That may also apply to the dGPUs you mention as well, but I don't have a GPU so I couldn't really say.
Upgrades seem to me to have become progressively more difficult to achieve for progressively smaller actual benefits, though I don't regret my adventure of some years with Hackintosh; my current hack is a lot faster and more reliable than most of the Macs i've seen recently, though I don't consider myself a 'pro' user with 'pro' needs. And the prices, let's not forget the prices, which in my view are Apple's own admission that they're on thin ice and need to gouge where they think they can get away with it. Pity though, I quite like Mojave, though I suspect staying with Yosemite (or even Mojave 10.14.1) might have been ideas I did not explore sufficiently well.
All in all, I think Macos is staggering and will fall in due time - I think the Apple tea-leaves only contain IOS, iPadOS and services so perhaps I'll just box on with 10.14.2 (which is at least stable except perhaps for the flakiness of the USB3 thing - I'm not an SSDT type of person I think). I know they're 2 quite different beasts but Windows is becoming more attractive almost by the day, probably partly because I have no dog in the updating race. though I know many do.
Interesting to read some of the more scathing analyses of Tim Cook's contribution to Apple, and I've thought for a while that Jony Ive has his own thoughts on that matter, despite being what I consider to be the driving force behind what has so far been Apple's rising star.
Thanks for your thoughts though. It would be interesting to hear other opinions as well.
