Where do I find this ".minecraft" folder (why is there a "." there?) Also confused by you saying don't delete it, so DO NOT delete the ".minecraft" folder, okay (not that I know where that is)
Then you mention "user folder", okay where is that?
Keep in mind I'm on a Mac, maybe things are in different places?
THIS COMPLETELY SUCKS, I HATE THIS, YOU PAY FOR A GAME, AND YOU GET F*CKED LIKE THIS, JUST PLAIN HORRIBLE!!!!!!
Yeah, I'm not a mac person, sorry. This ".minecraft" folder is a place where your saved worlds, minecraft.jar, and texture pack are stored in. If you poke around on the forum, you may find out which folder it's placed on Mac.
PS: If you think it sucks, shouldn't have brought a "beta" game then. Nothing wrong to have bit of common sense.
