🔧 Commands

Patch Slack

./slack_patcher.sh patch

For macOS users with integrity checking:

./slack_patcher-v2.sh

Restore Original Slack

./slack_patcher.sh restore

macOS Integrity Checking

For macOS users, slack_patcher-v2.sh includes automatic integrity checking to ensure Slack launches properly after modification:

# Calculate file integrity (used automatically by patcher)
node integrity.js /Applications/Slack.app/Contents/Resources/app.asar

The macOS patcher automatically:

• Detects your CPU architecture (ARM64/Intel)
• Calculates checksums for the modified ASAR file
• Updates Info.plist files with new checksums
• Ensures Slack's signature validation passes

Note: On macOS, the integrity replacement runs from /Applications/Slack.app/Contents and updates all files containing the old checksum.

🛠️ Development & Debugging

Making Changes

1. Edit custom_slack_ext.js
2. Run ./slack_patcher.sh
3. Restart Slack
