Does it feel, though, like Apple is neglecting MacOS in favor of IOS recently? iPhones and iPads seem to be marching forward while desktops and laptops seem a bit stagnant.

They gave up the server line entirely, and the "pro" moniker seems to not mean what it meant in the past. Even the super popular Mac mini seems to be lacking investment.

It would be interesting to see an internal view of growth of investment dollars going into MacOS/desktop/laptop vs the tablets and phones. The recent bugs and vulnerabilities certainly seem to point at some neglect.
