currently on macOS Mojave, Ver 10.14.6 on my macbook air bought in mid 2019.
I have tried downloading the Update to Catalina at least 4 times, couldn't taste any success yet.
it downloaded the entire 8.16 GB but something went wrong and showed me an error and started again from scratch. and the other times i tried, it stopped midway and started downloading again from scratch.
anyone experiencing the same trouble?
how do i get it done?
