I downloaded optifine from the optifine website, and much to my dismay there was no automatic installer. I tried to make a folder named "1.10.2-OptiFine_HD_U_C2" in the versions folder of the minecraft folder, which contained the optifine .jar file, and I put the optifine .jar file in the versions folder by itself. However, when I tried to make a profile in the launcher, that version didn't show up. How can I get optifine? Btw, mac.
