Lot to unpack here. Torvalds has a Apple hardware running Linux. Apple hardware not Apple OS. It’s like baskets and fruits.
He also doesn’t build anything he just reviews PR nowadays.
(Free)BSD is not a toy. Code is used on a lot of enterprisey stuff. It powers Netflix, runs firmware on all Sony PlayStations since 3. Juniper, Netgate, NetApp.
Definitely not a toy.
