That seems weird to me. I remember 20 years ago one of the whole points of macOS version 10 was display PDF, i.e. a vector based UI.

That seems weird to me. I remember 20 years ago one of the whole points of macOS version 10 was display PDF, i.e. a vector based UI.
While the original OS X display model, Quartz, evolved from Display PDF via NextStep, I believe that it shifted back to pixel rasterization to offload more of the display stack onto the GPU.
Quartz Extreme?
John Siracusa, Ars Technica:
It's possible that existing consumer video cards could be coerced into doing efficient vector drawing in hardware. Apple tried to do just that in Tiger [note], but then had to back off at the last minute and disable the feature in the shipping version of the OS. It remains disabled to this day.
