Because of all the problems with Apple UPGRADES, I am staying very far away from macOS Big Sur. I have Catalina on my MBP and my iMac and though not perfect, I am not at all willing to UPGRADE to anything that undoubtedly will be quite problematic. All of the current NEW Apple Operating System UPGRADES have issues and they may not be resolved and stable for several months. What ever happened to Quality Control and "not shipping anything until it WORKS"? Too bad, many have lost faith in Apple.The better question would be "why are folks installing Catalina" ?
