Follow these steps to prevent a possible "Black Screen" problem when installing OptiFine:

1. Temporarily revert back to the Default Texture Pack.

2. Uninstall the HD Textures, HD Fonts, and Better Grass mods from the MCPatcher. These functions are included in OptiFine.

3. Set Graphics to Fancy

4. Install OptiFine and test with the Default Texture Pack to make sure everything is working.

5. Select your previous texture pack and graphics settings

6. Run Minecraft and enjoy

When installing OptiFine together with other mods always make sure to install OptiFine last. The only exception are mods which are designed to be installed after OptiFine and say so in their install instructions.

If you need ModLoader: Install OptiFine AFTER ModLoader.

If you need Forge: Install OptiFine AFTER Forge.

MCPatcher is NOT needed for HD textures, HD fonts and BetterGrass, they are included in OptiFine. Install OptiFine without MCPatcher's HD features for best performance.

If you need DynamicLights (ModLoader edition): Install OptiFine AFTER DynamicLights.

Compatible with: ModLoader, Forge, SinglePlayerCommands, TooManyItems, PlasticCraft, CJB's Modpack, Zan's Minimap, Rei's Minimap, DynamicLights, GLSL Shaders 2, LittleBlocks and many other.
