yichen-mac-wechat-dual-open

Create, inspect, repair, and polish a second WeChat app on macOS by copying WeChat, changing the bundle identifier, ad-hoc re-signing, preparing it for the user to open manually, setting Chinese language preferences, and recoloring only the copied app icon from WeChat green to blue. Use when the user asks whether Mac WeChat dual-open methods from X/Twitter or scripts are reliable, asks to prepare a second WeChat app, fix WeChat-2 language/icon/cache issues, or make the copied app visually distinct without installing third-party injection tools. Never launch or control WeChat.
