So I accidently installed 1.5.1 on my mac and can't find a tutorial on how to remove it. My favorite server is 1.4.7 and thats what I want to go back to. If you have a tutorial please explain it to me like im 5, im not the best with computers, but any help will be appreciated.
Then open up finder, and find your way to:
~/Library/Application Support/minecraft/bin
Then drag the thing you downloaded into there and if it asks you to replace, do it.
Open up minecraft; and it should boot you directly in it.
