Ok, so I wanted to download optifine but my problem is that me my sister and my brother have different accounts on the same computer. So when I download optifine will it go to all accounts or will it go to one account. (I saw a tutorial and it makes a whole new profile so what account will it go to? Also, which account data will it keep for servers?) This is my first time downloading a mod so I am just curious of what it will do. Thanks!
I need a clarification on mods
