Cross-Platform Device Setup for Claude Anti-Ban

1. macOS Timezone & Regional Settings

macOS system preferences directly affect browser fingerprints. Configure timezone, language, and region settings to match your proxy exit region:

Timezone Configuration

# Check current timezone
sudo systemsetup -gettimezone

# Set timezone to US Eastern
sudo systemsetup -settimezone "America/New_York"

# Alternative: US Pacific
sudo systemsetup -settimezone "America/Los_Angeles"

# UK London
sudo systemsetup -settimezone "Europe/London"

# Singapore
sudo systemsetup -settimezone "Asia/Singapore"

# Verify Intl timezone matches
node -e "console.log(Intl.DateTimeFormat().resolvedOptions().timeZone)"

Language & Region Settings

• Open System Settings → General → Language & Region
• Set Preferred Language to "English (United States)"
• Set Region to "United States" (or UK/SG if using those proxies)
• Remove all Chinese language entries from the language list
• Restart browser to apply changes

2. Windows Environment Variables & Registry

Windows stores timezone and language settings in registry keys. Modify them system-wide to ensure consistency:

PowerShell Timezone Configuration

# List available timezones
Get-TimeZone -ListAvailable | Where-Object { $_.Id -like "*Pacific*" }

# Set timezone
Set-TimeZone -Id "Pacific Standard Time"

# Verify
Get-TimeZone

# Alternative zones:
# "Eastern Standard Time" (US East)
# "GMT Standard Time" (UK)
# "Singapore Standard Time" (Singapore)

Registry Language Settings

# Set system locale to en-US
Set-WinUserLanguageList -LanguageList en-US -Force

# Remove Chinese input methods
Get-WinUserLanguageList | Where-Object { $_.LanguageTag -notlike "zh-*" } | Set-WinUserLanguageList

# Verify
Get-WinUserLanguageList

3. Linux Terminal Environment & Font Isolation

Linux systems require manual environment variable configuration and font management to prevent Chinese fingerprint leakage:

Timezone & Locale Setup

# Set timezone
sudo timedatectl set-timezone America/New_York

# Verify
timedatectl

# Set system locale to en_US.UTF-8
sudo localectl set-locale LANG=en_US.UTF-8

# Add to ~/.bashrc or ~/.zshrc
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export TZ=America/New_York

# Reload shell
source ~/.bashrc

Font Isolation (Remove Chinese Fonts)

# List installed Chinese fonts
fc-list :lang=zh

# Option 1: Temporarily disable Chinese fonts
mkdir -p ~/.config/fontconfig
cat > ~/.config/fontconfig/fonts.conf <<'EOF'



  
    
      
        
          Noto Sans CJK
          WenQuanYi
          AR PL
        
      
    
  

EOF

# Rebuild font cache
fc-cache -f

# Option 2: Uninstall Chinese font packages (Debian/Ubuntu)
sudo apt remove fonts-wqy-* fonts-arphic-* fonts-noto-cjk
