Mac Minecraft download fail/stop

So, basically, I am using this mac computer for nearly 2 years. And even until few months ago, minecraft worked without any problem on this computer. However, when I made my macbook into factory setting (clear out) and tried to reinstall and play minecraft today with 1.12.2 version, it didn't download. Out of 163~165 MB of file to download, it just stops on 160MB remaining with a file downloading forever. And if I wait for a long time, it ends with a crash. When I searched up for internet, it told me to turn off my security in mac, and I did but didn't make any improvements. I even did it with the older launcher, but it is still the same. Do you have any methods to solve this?
