Step 2: Finder Work
Go into Finder, Library, Application Support, Minecraft. Go to Minecraft.jar and right click it. Then select open Minecraft.jar. NOTE: MAKE SURE YOU SELECT "OPEN WITH UNARCHIVER" OTHERWISE, IT WILL NOT WORK!
Step 2: Delete and Open
Delete the Minecraft.jar and right click the minecraft folder. Select "Rename" and type in minecraft.jar (it will not change to the .jar it will stay as a folder) and a little window will pop up saying "Are you sure you want to add .jar?" click apply or yes.
Step 3: Delete and Add
Go into the Minecraft.jar folder and look for the META-INF folder. Delete it (move to trash) and then open another finder window.
Search for TooManyItems in the search bar or go through the Application Support rush. Unzip the .zip and move ALL files/classes to the Minecraft.jar. Once A L L files are in Minecraft.jar...
Run Minecraft and Enjoy the mod.
I get a black screen.
There is another way to install it. Use the ModLoader from Risugami.
The mod is not showing up.
Are you SURE you didn't delete the META-INF folder OR put A L L files/classes into Minecraft.jar. If you still don't see it after these double checks, install it with the ModLoader.
