There were a few system breaking bugs in Big Sur beta and also a security breaking one that circumvent the firewall/sandbox for apps. It looks like 11.1 that's in RC now, address the known bugs, I'm actually impressed at how fast they fix the bugs. If Apple now focus on stability, like Microsoft is doing with Windows 10, I think MacOS can grow significantly, especially together with their new custom silicon.
