Crimson Desert Font Modder for macOS (Native/Steam)

📖 Introduction

While Windows users have various patching options, Mac users often face unique challenges due to system security (SIP/Quarantine). This tool simplifies the process for the Mac community, ensuring a seamless font customization experience without manually tinkering with deep system files.

✨ Key Features

• Full Font Overwrite: Patches all 16 internal font slots (Korean, English, Japanese, etc.) with your custom .ttf or .otf file.
• macOS Native Support: Specifically targets the file structure found in the Mac version (e.g., basefont/*.ttf).
• High-Performance Patching: Optimized logic using LZ4 compression to match original file budgets perfectly on macOS.

🛠 Requirements (First-time only)

You must have Python and the necessary libraries installed. Run these commands in your Terminal:

1. Install Homebrew (if not installed)

/bin/bash -c "$(curl -fsSL [https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh](https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh))"

2. Install Python-tk and LZ4 library

brew install python-tk@3.12
pip3 install lz4

🚀 How to Use

Step 1. Permissions

Go to System Settings > Privacy & Security > Full Disk Access and enable Terminal. (Please restart your Terminal after this step!)

Step 2. Run the Tool

Navigate to the tool's folder in Terminal and run:

python3 CrimsonDesertFontModGUI_Mac.py

Step 3. Patching

Click [Browse] to select your custom font file.

Click [Force Patch Fonts] to begin the process.

Step 4. Final Step (Bypass Quarantine)

Run this command in Terminal to ensure the game launches without security errors:

sudo xattr -rd com.apple.quarantine "/Users/$(whoami)/Library/Application Support/Steam/steamapps/common/Crimson Desert/CrimsonDesert_Steam.app"

Note

If the game updates and the font resets, simply run the tool again.
