So I go to download the Technic Launcher but it just sits on the logo, I have downloaded jdk 8-10 multiple times to no avail, I have restarted my computer, deleted and reinstalled java, made sure everything was the mac download and not windows or some other system, and tried putting things into a terminal, but when I open the launcher it just sits in the middle of my screen and taunts me. please help.
