# ChatGPT Published January 1, 2026 · Updated August 10, 2026 OpenAI's official ChatGPT desktop app for macOS Category: Developer Tools · Free · Replaces Jasper AI ($69/month) · [Official website](https://chatgpt.com/) ## Install with Homebrew `brew install --cask chatgpt` ## Quick take ChatGPT's July 2026 Mac desktop rebuild makes it the default OpenAI install: Chat, Work, and Codex in one place on GPT-5.6 Sol/Terra/Luna. Plus at $20 remains the sweet spot; Pro is for quota pain. Atlas is dead. Do not confuse this app with the discontinued browser. For pure repo agents you may still prefer Cursor or Claude Code, but as a system-wide assistant ChatGPT for Mac is essential infrastructure. Best for: Professionals who want one desktop AI for writing, analysis, and light coding, Developers using Codex alongside chat without a second app, Teams standardising on OpenAI Business/Enterprise, Anyone migrating off discontinued ChatGPT Atlas ## What is ChatGPT for Mac? ChatGPT for Mac is OpenAI's official desktop client for ChatGPT on macOS. As of the 9 July 2026 rebuild, it is no longer "just a chat window": OpenAI shipped a unified shell that brings Chat, ChatGPT Work, and Codex together, while the previous macOS client was positioned as ChatGPT Classic for people not yet moved over. The desktop app remains the deepest system integration OpenAI offers on Mac, including a global summon shortcut, screen context options, voice on eligible plans, and access to the GPT-5.6 model family. Models in August 2026 centre on GPT-5.6 Sol, Terra, and Luna (general availability from 9 July 2026). Free and Go users skew toward Luna/Terra-class everyday chat with limits; Plus and above unlock advanced GPT-5.6 reasoning including Sol, with Sol Pro-style higher effort on Pro tiers. On 30 July 2026 OpenAI cut API-side Luna pricing ~80% and Terra ~20%, reinforcing Luna as the volume everyday model. Content that still sells "legacy GPT-4 class models" or early GPT-5.4/5.5-only framing is stale. Pricing ladder (USD individual, verify on chatgpt.com/pricing): Free $0 (ads in some regions, limited messages/uploads, unlimited text chats with GPT-5.6 Luna as that rollout completes); Go about $8/month for longer/cheaper volume without full frontier access; Plus $20/month, the default professional tier with advanced GPT-5.6, projects, scheduled tasks, custom GPTs, expanded Codex and Work; Pro from $100/month (5×) and $200/month (20×) with Sol Pro reasoning and maximum headroom; Business roughly $25/user/month monthly or ~$20-25 annual packaging depending on billing; Enterprise custom. Strategic context: OpenAI discontinued ChatGPT Atlas as a standalone browser with a 9 August 2026 stop target, folding agentic browsing lessons into this desktop app and Chrome integrations. If you are choosing one OpenAI Mac install today, it is ChatGPT desktop, not Atlas, and not the old standalone Codex app (merged 9 July 2026). macOS support includes Apple Silicon and current macOS releases through the Tahoe 26.x era. The app is widely distributed via direct download and Homebrew cask `chatgpt`. Competitors on Mac include Claude desktop (Cowork + Claude Code), Gemini for Mac with Spark, Perplexity, and IDE-native agents (Cursor, Muse Code, Copilot). When comparing Free versus Go, treat Go as a volume upgrade for people who mainly need longer Luna/Terra chats without paying Plus prices for Sol. ## Features - **Unified Chat + Work + Codex desktop.** July 2026 rebuild merges general chat, ChatGPT Work for multi-step professional tasks, and Codex for coding agents in one Mac app. Replaces juggling separate Codex and chat clients. - **GPT-5.6 Sol / Terra / Luna.** Frontier model family for ChatGPT. Sol for hard reasoning (Plus+), Terra balanced, Luna cheap/fast volume. Pro adds higher-effort Sol Pro capacity. Stale "legacy GPT-4 class models" marketing no longer describes the product. - **System-wide summon and screen context.** Global shortcut overlays ChatGPT above any app. Screen context (where enabled) lets you ask about the frontmost window, code, docs, or error dialogs, without manual screenshots every time. - **Projects, custom GPTs, scheduled tasks.** Plus and higher organise long-running work into projects, reusable custom GPTs, and scheduled tasks that continue work over time. - **Voice and multimodal tools.** Advanced voice on eligible paid plans, image generation with plan-based rate limits, file analysis, and data tools for spreadsheets and code. - **Codex in the desktop shell.** Coding agent workflows that previously lived in a standalone Codex app now update into the unified ChatGPT desktop experience for Mac and Windows. ## How to Install ChatGPT on Mac Prefer the official July 2026+ desktop build, not abandoned third-party wrappers. 1. **Download or Homebrew.** `brew install --cask chatgpt` or install from openai.com / chatgpt.com desktop download. 2. **Sign in.** Use your OpenAI account. Workspace SSO applies on Business/Enterprise. 3. **Enable accessibility/screen permissions.** Grant permissions if you use screen context or advanced desktop features. 4. **Set the global shortcut.** Choose a summon key that does not fight Spotlight or Raycast (Option+Space is common if free). ## Pros - Best generalist AI assistant ecosystem on Mac with deep desktop integration - Unified Work + Codex removes app sprawl after July 2026 - GPT-5.6 family covers cheap Luna volume and expensive Sol reasoning in one account - Huge plugin/custom GPT ecosystem and brand familiarity for teammates - Free tier remains useful for light chat after Luna unlimited-text rollouts - Actively maintained, unlike discontinued Atlas ## Cons - Usage limits still frustrate daily power users on Plus. Pro pricing is steep - Model capacity messages ("at capacity") still appear on high tiers during peaks - Privacy-sensitive orgs may prefer Claude Enterprise or self-hosted stacks - Desktop app capabilities vary by plan; Free is not the full Work/Codex story on every surface - Not a replacement for IDE-native agents when you need tight repo coupling all day ## Closer look: ChatGPT as Mac system layer How the 2026 desktop super-app strategy changed Mac AI installs. ## FAQ ### What models does ChatGPT use in August 2026? The GPT-5.6 family. Sol, Terra, and Luna, is the current centre of gravity after 9 July 2026 GA. Plus and higher get advanced Sol reasoning; Free/Go emphasise Luna/Terra volume.
