MacOS Big Sur

Rajawali

I have been following discussions about MacOS Big Sur and Bitdefender last year. I have a MacBook Air 2020 with macOS Catalina V10.15.7. I have been a bit reluctant to install BigSur based on the comments of the late 2020 discussions as I am just a casual computer user. Is there any new. improvement which would allow for the safe upgrade to BigSur now ? Any input would be appreciated.
