Since Big Sur is being released tomorrow (Thursday), I thought this article on which Macs will work with macOS Big Sur would be timely. There is nothing more disappointing than trying to install an operating system on a machine that is not designed to handle. I still have not made up my mind whether to install Big Sur right away or wait. Catalina is so buggy, it drives me crazy. I might just wait a few days to determine if there are any major problems before installing.
