The new ChatGPT app for Mac is a confusing mess, according to the article. To get the new app, users must manually re-download it from OpenAI's website, as a regular update only triggers an updated version of the old app. The new ChatGPT is essentially the old Codex merged with ChatGPT, designed to resemble Anthropic's Claude Mac app, which the article also describes as a mess. The app is no longer a native Mac app but a bloated Electron package, making it less performant. A major issue is the UI, particularly the 'ChatGPT Work' feature, which the author initially mistook for an enterprise version. The branding is described as insanely clunky, as 'Work' evokes Microsoft's enterprise suite or the English language, rather than the intended reference to 'Claude Cowork'.
