Mac OS is adding support because they realize that they are gonna miss a good portion of consumer base to windows laptops running on Nvidia Spark since people can get the perfect machine for gaming and dev.
The big thing with Windows laptops is historically, they were slightly more sluggish than Macs because the os/hardware wasn't optimized. On desktops with enough performance, Windows has been king ever since WSL2, considering you can do everything with that system (WSL2 can even run I3WM if you care enough since they have an X server).
Now with Spark and ARM, you can pretty much get a perfect laptop that supports gaming as a first party, can run any windows only software (like CAD for example), and also has WSL2 which is very natively integrated with windows to where it supports CUDA with native like performance.
