macOS 11 (bigSUR) the correct way to fix all errors, very awesome update

Описание: So basically I was still running Mojave, and I had downloaded Catalina a few months ago but did not install it, I tried to install Big Sur, but ran into all the errors that everyone else did, so I decided to install Catalina, and then tried Big Sur afterwards, and that was the fix, now the file is 12.18g, and it will take a long time, but just be patient. The download bar won’t reach the end, but it will say 12.18 of 12.18 and will look like it’s in a frozen state, just let it work it’s magic
