I decided to add some mods, so I installed forge. I installed it by replacing the files in my minecraft.jar. And i got rid or META-INF. It doesnt black screen but it freezes on the white "mojang" screen. I let it load for about 15 minutes and it just stayed the same. Right when i first open minecraft and start it, it says, "FML is started up your minecraft enviroment" and then it says "FML has to complete some tasks" I dont know what that means but i figured it meant that forge was installed. I ALWAYS get frozen on the mojang screen. Anyone know why? I have a Mac if that makes a difference. Thanks
Do you have anything else installed? If you just have forge that probably means you don't have the right version or you didn't do it quite right. Just force update and try again. FML is part of forge and you need to let that load before you put anything else in. So put in forge, load minecraft, and then put in your other mods.
