I tried to install command line tools to Ethereum. I follow this tutorial
I already do this commands :
brew update brew upgrade brew tap ethereum/ethereum brew install ethereum
And after I do this :
But since for 30 min I have this:
What is it? I think this downloads something but where?
Moreover I read the tutorial and after this command I must connect to private network. But can I connect to main network? If it's possible how can I do this?
I'm beginner, and I don't have any accounts, so before connect to a network, must I create an account?
