ChatGPT Desktop customization · native first

Customize ChatGPT Desktop on Mac beyond colors and fonts

Use native Appearance for basic choices, then choose a ready CC Theme package for image or video backgrounds in ChatGPT Desktop, including Codex mode.

Start with host-owned Appearance

Native settings move with the client and remain the most stable place for basic colors, UI fonts and code fonts.

  • Choose light or dark appearance
  • Check chat and code contrast
  • Use official sharing when native controls are enough

Codex theme vs Codex skin: native colors, fonts and full backgrounds

For basic colors and typography, use ChatGPT Desktop Settings → Appearance. For a complete image or muted video background across the workspace, choose a finished .cctheme package with a full preview, declared media and a verified mac-codex application path.

  • Native Appearance for light, dark, foreground and fonts
  • Prepared packages for full image or video backgrounds
  • No layout replacement or product-behavior change

Choose a prepared package for advanced backgrounds

CC Theme packages are already made and versioned. They avoid extra generation tokens, repeated prompt tuning and visual prompt lottery.

  • Download from the published theme Release
  • Verify SHA-256

Keep application and recovery explicit

CC Theme validates the package, detects the supported client and compiles through mac-codex for a verified ChatGPT Desktop target.
