How do I get to the Minecraft Launching Terminal?

I play Minecraft on a Mac and was wondering how to get to the Minecraft Launching Terminal, because my Minecraft keeps crashing at the Launch screen without it. I am hoping that after I get to the launching terminal, I can input a certain code (found it on a different website and it worked for a lot of people) and it will work. All I need to know is how to get to the Minecraft Launch terminal.

It's not the Minecraft Launching Terminal, it's a program that comes with your Mac called Terminal. Use the search bar of any Finder window or the search feature of the Launch Pad to search for "terminal".

When Minecraft stops loading at the end of the loading screen, this is often caused by malware or adware - for example, like PremierOpinion
