OpenAI Codex "For (Almost) Everything" Update Complete Guide — AI Takes Over Your Mac [April 2026]

On April 16, 2026, OpenAI shipped five major features to Codex simultaneously. The centerpiece is Computer Use — the ability for Codex to directly operate any app on your Mac. This transforms Codex from a coding assistant into a full desktop AI super-app that controls your entire Mac environment, with 90+ plugin integrations, gpt-image-1.5 image generation, cross-thread Memory, and persistent multi-day task execution all launching at once.

Here is a summary of all five capabilities introduced in this update:

Codex uses a proprietary computer use implementation to visually perceive the screen, then click and type in any macOS application. Multiple agents can run in parallel in the background. Each app requires individual authorization through a system called App Approval, providing a two-layer safety mechanism that reduces the risk of unintended actions or data leakage.

The new plugin ecosystem spans development, productivity, design, and data domains:

With 90+ integrations, most professional workflows can now be completed without leaving Codex.

Codex now integrates OpenAI's gpt-image-1.5 (successor to the DALL-E series) directly into the coding workflow. UI mockups, architecture diagrams, game assets, and concept visuals can be generated within the same thread as your code, eliminating the need to switch to ChatGPT. This substantially shortens design-to-implementation cycles.

Memory works by injecting information gathered from past threads as context, without modifying model weights. It captures your coding style (indentation, naming conventions), preferred tech stack, project-specific workflows, and repeated patterns. Users can view, edit, or delete memory contents at any time from the Settings panel, preserving user control over stored data.

Persistent tasks allow Codex to autonomously execute instructions over days or weeks. Supported capabilities include resuming interrupted tasks, scheduling future executions, and cloud-based triggers (Heartbeat). Codex continues working in the background even when your laptop is closed and notifies you when results are ready.

Computer Use currently supports macOS only. Windows users are limited to CLI-based coding assistance, and mobile is not yet supported. The EEA (European Economic Area), UK, and Switzerland face regional restrictions on Computer Use and portions of Memory due to privacy regulations. OpenAI has stated that broader rollout will follow once compliance requirements are met.

Here is what each plan offers in terms of the new features:

Free and Go plans offer limited access. Plus or above is recommended for full functionality.

The original Codex was specialized for file and codebase operations. This update expands its scope dramatically:

In March 2026, the Wall Street Journal reported that OpenAI was planning to unify ChatGPT, Codex, and Atlas Browser into a single super-app. The April 16 Codex update represents the first phase of that strategy. It signals a clear intent to make Codex the primary desktop AI surface for professional users, with deeper integrations expected in future updates.

Here is how Codex stacks up against major AI coding and agent tools:

Codex is the strongest option for Mac-focused developers. Claude Computer Use leads for cross-OS environments.

Here are five real-world scenarios where the new Codex excels: 1. Morning routine automation — Check Slack, review Jira tickets, and run code review in sequence 2. Design sprint — Operate Figma to generate mockups, then implement the resulting UI 3. Research automation — Browse multiple tabs, synthesize findings, and produce a report autonomously 4. Continuous code review — Memory learns your PR patterns weekly and improves feedback accuracy 5. Multi-tool workflow — Create a Linear issue, open a GitHub PR, and set up Sentry monitoring in one flow

Computer Use requires screen recording permission in macOS System Settings. Each app also requires individual approval through App Approval. Memory can be opted out and reviewed or deleted from the Settings panel at any time. The EEA exclusion is primarily driven by GDPR and related privacy regulations. Before deploying Codex in sensitive environments, verify alignment with your organization's security policy.

1. Download and install the Codex app from the Mac App Store 2. Go to System Settings → Privacy & Security and grant Screen Recording permission 3. Open Codex Settings, enable App Approval, and authorize each app individually 4. Browse the plugin store and install desired services (Jira, Figma, etc.) 5. Enable Memory in Settings and configure which types of information Codex should retain

On April 9, OpenAI launched the Pro tier at $100/month, significantly expanding Codex usage quotas. The April 16 feature additions were coordinated with this pricing change, positioning Computer Use and persistent tasks as premium differentiators for higher-tier plans. Codex is clearly becoming OpenAI's second major revenue pillar alongside ChatGPT.

Online reactions have been broadly positive regarding Codex's evolution into a super-app. However, some users expressed preference for it remaining a focused coding tool, and EEA users voiced frustration at being excluded. Among power users, a three-tool setup of Cursor (IDE autocomplete), Codex (Mac control and plugin workflows), and Claude Code (deep code analysis) is becoming the established workflow.

Q1. Is Computer Use available on Windows? A. Not yet. Computer Use is currently macOS-only. Windows users are limited to CLI-based coding assistance. Q2. Can I use the new features on the free plan? A. Free and Go plans have limited access. Plus ($20/month) or above is recommended for full Computer Use, Memory, and persistent task functionality. Q3. Which apps can Codex control? A. In principle, any app running on macOS. However, each app must be individually authorized via App Approval. Q4. What image model does Codex use? A. gpt-image-1.5, the successor to the DALL-E series from OpenAI. Q5. How do I reset my Memory? A. Go to Settings → Memory in Codex to review, selectively delete, or fully reset stored information. Q6. Is Codex available in the EU? A. Computer Use and portions of Memory are currently restricted in the EEA, UK, and Switzerland. A timeline for rollout has not been announced. Q7. Should I choose Codex or Claude Computer Use? A. If you work primarily on Mac, Codex offers a tighter integration. For cross-OS environments including Windows and Linux, or for web-based control, Claude Computer Use is the stronger choice.
