Download and installation questions

How do I download CC Theme?

Use the Download CC Theme button on this page. It downloads the immutable CC Theme App 0.2.2 Apple Silicon DMG from the official GitHub Release.

Do I need separate ChatGPT Desktop and WorkBuddy apps?

No. Install one unified CC Theme App. It detects supported clients and selects mac-codex or mac-workbuddy at runtime.

Do I need Node.js, Rust, Homebrew or a source build?

No. End users download and open the CC Theme App, then import a .cctheme package.

How do I import and apply a theme?

Download a versioned package, import it into CC Theme, let the app validate it, select a verified detected client and choose Apply.

How do I restore native appearance?

Open CC Theme, pause the active Adapter and use Restore for that client. Restore removes CC Theme appearance; it does not modify or recover chats.
