I am on a Mac..... BOO. version 10.5.8 with Java version 1.5.0_26 (Just updated Java) I am having the worst time trying to install ModLoader and NOT getting a black screen, or a frozen partial loading screen. I am not stupid... for the most part. I know how to follow directions but I can't seem to get any ModLoader to work. I am on version 1.6.6 but have the .jar files for 1.6.4 and 1.5. I have tried to install specific ML for the 1.6.4 and 1.6.6 (so they said) but to no avail... I am doing it all manually without the terminal. (command prompt for windows users). I don't see a point in using the terminal unless you just want to be specific... IDK. I find manual to be easier. These are the steps I follow: Extract minecraft.jar with unArchiver Delete original minecraft.jar file or backup (now I only have an uncompressed folder with .jar extension) (game still runs) Open minecraft.jar folder and copy contents of downloaded ModLoader into minecraft.jar folder (this part is weird cuz I have downloaded multiple files and they all seem to be inconsistent on the ammount of files AND file names... I don't know EXACTLY what I am needing to replace.) ALT 1: Run minecraft without compressing folder back down (Does not run, black screen or freezes at load screen: this SHOULD work since it worked before I copied files to it.) ALT 2: Compress folder and run minecraft (Same experience from previous step) Minecraft SHOULD run with just ModLoader installed correct?
