Codex for Mac gets agentic upgrades

OpenAI has rebuilt Codex for Mac into a desktop agent that can use apps, browse pages inside the app, and generate images. (openai.com) OpenAI announced the overhaul on April 16, 2026, in a post titled “Codex for (almost) everything.” The company said the macOS and Windows apps now add computer use, in-app browsing, image generation, memory, plugins, and deeper developer workflow tools. (openai.com) For Mac users, the most immediate change is “computer use,” which lets Codex see and operate graphical apps when command-line tools are not enough. OpenAI’s developer docs list checking desktop apps, changing settings, reproducing graphical bugs, and working with data sources outside plugins as examples. (developers.openai.com) The app also now includes an early in-app browser for opening local or public pages that do not require sign-in. OpenAI said users can comment directly on a rendered page and ask Codex to fix page-level issues from that feedback. (developers.openai.com) Image generation is part of the same workflow, with Codex using OpenAI’s `gpt-image-1.5` model inside the app. OpenAI and MacRumors both described that as useful for product concepts, mockups, and other visual assets that sit next to code and review work. (openai.com) (macrumors.com) Codex started this year as a desktop command center for running multiple coding agents in parallel on macOS. When OpenAI introduced the app on February 2, 2026, it pitched Codex as a way to manage long-running tasks, separate projects into threads, and collaborate with agents over time. (openai.com) The April update pushes that model past code generation and into surrounding desktop work. OpenAI said Codex can now review pull requests, open multiple files and terminal tabs, connect to remote development boxes over Secure Shell, and learn from previous actions through memory. (openai.com) OpenAI’s app docs say Codex is included with ChatGPT Plus, Pro, Business, Edu, and Enterprise plans, and the desktop app is available on macOS with Apple Silicon. A March 4, 2026 update to the launch post said Windows support had also arrived. (developers.openai.com) (openai.com) Outside coverage has framed the release as a direct expansion beyond “agentic coding.” 9to5Mac wrote on April 16 that the new version adds three features that widen Codex into a broader desktop workflow, while Decrypt described it as part of OpenAI’s push toward a larger “super app” shape. (9to5mac.com) (decrypt.co) OpenAI has not said that the in-app browser is finished. Its changelog calls the browser “early,” and outside reports say fuller browser control for opening sites, stepping through flows, taking screenshots, and inspecting results is still ahead. (developers.openai.com) (macrumors.com) For now, the shift is concrete: Codex on Mac is no longer just a coding window. OpenAI is turning it into a desktop workspace where writing code, checking interfaces, browsing pages, and making assets happen in the same app. (openai.com)
