when they were at their almost-10-percent-high, they made an effort and had unique, high-quality and competitively priced machines. now half of their lineup is slowly dying. if you buy a new mac, you can't be sure that there'll be a follow-up model in that line. macpros and mac-mini sales are probably pretty flat, because of that and because of old hardware that was on the cusp of being overpriced when it was released three years ago.
new releases value aesthetical design over function and are no good value for the money. no wonder even the most hardcore mac fan nowadays lives in a mixture of sorrow and fear of what they will (not) release next.
apple is slowly eroding the fundament and fallback under it's iphone - business, but they fon't seem to care because they are still sitting on a mountain of cash, that only looks like it's getting smaller when you look at it from a distance.
the sad thing is, that there's still no competition for mac/macOS in a few areas - but as soon as a new player emerges (not counting on microsoft and linux, rhey blew it for decades, but inevitably some day somebody else will have the money and the focus) there'll be hell to pay,
