Ah, asking the real questions. The speed of a closed ecosystem CPUs such as Apple's is irrelevant. As long as Linux or BSD doesnt't run on it in a stable fashion, I'm not interested.
It's not even that Linux is that great. But Windows and MacOS user experience have degraded so much in the last decade due to user hostile decisions and lack of vision, they essentially nullify advances made on the hardware side.
POWER should be the real competitor. If only it had laptop class implementations...
I genuinely think that GNOME is more user-friendly than macOS by a wide margin.
The majority of computer users today are familiar with either Windows or iOS/Android primarily. They're not coming from UNIX CDE machines or Macs on-average, they want a desktop that behaves like their phone does and reinforces/rewards their intuition from Windows. They want to click (X) on a window to confidently close it, they want to mash the Start key to search for an app, they want to tap "Install" on a storefront instead of dragging a DMG icon into ~/Applications. All of the little idiosyncrasies that macOS clings to doesn't help people learn it.
