Issues on preparing software update while updating Big Sur
While I am restarting my computer after I began the Mac Big Sure installation, it said that there are issues on preparing the software update. Then it has the macOS update assistant program with a process bar, but didn't have any progress within the next half hour. There was issues with the space of my Startup disk, but after I empty the trash can, I could download the Big Sur package.
