Anthropic is back with another big update. The company just introduced Opus 4.5, its newest and most capable AI model yet, and it also expanded Claude Code to desktop apps for the first time.
Whether you use macOS or Windows, this is a meaningful upgrade, but Mac users in particular are getting a workflow boost that was long overdue.
Opus 4.5 Feels Like a Serious Jump Forward
Anthropic describes Opus 4.5 as more intelligent, more efficient, and better at coding and multi system reasoning. It replaces Opus 4.1 and early testers inside the company are calling it a major leap forward. They said it handles ambiguity, works through tradeoffs on its own, and fixes complex bugs without needing every detail spelled out.
The most interesting part is that everyone testing it seemed to say the same thing. Opus 4.5 “gets it.” That is probably the best compliment an AI model can get right now. Half the battle with AI tools is convincing them not to hallucinate, guess, or freeze. If Opus 4.5 reduces those headaches, it will be a big win for developers and power users.
Anthropic also says it uses fewer tokens to complete similar tasks, which is good news for anyone who uses AI heavily and cares about cost efficiency.
Claude Code Arrives on Desktop, with a Strong Push Toward Mac
Claude Code was previously limited to the web and mobile apps, which always felt backward for a feature designed for software engineers. Developers work on desktops, not phone screens. Now the tool is available on the desktop app, including the Mac version, and it finally feels like it fits into a real developer workflow.
You can run multiple local and remote sessions, generate and edit code, research problems, and switch between projects without juggling browser tabs. The Mac app gets a noticeable productivity boost here, which is great considering how many developers prefer macOS for work.
Windows users benefit too, but there is clearly a heavier lift for Mac right now. It is not exactly surprising. A huge chunk of the dev community lives on MacBooks.
Longer Conversations with Fewer Interruptions
Anthropic also improved the conversation limits across desktop apps. Claude can now summarize earlier parts of long chats automatically. You can keep going without worrying that the thread will hit a wall, which is especially helpful for coding, planning, writing, or long running technical conversations.
Final Thoughts
Anthropic is clearly aiming directly at developers and technical users with this update. Opus 4.5 sounds like a genuine upgrade, not just a small version bump. And bringing Claude Code to desktop apps, especially on the Mac, finally makes it feel like a complete tool rather than something you only use in the browser.
If the performance gains from early testers hold up, this might be one of the best AI coding assistants available right now.
