The best Mac setup isn't the one with the most apps. It's the one where every app earns its place. Here are 8 apps that cover AI, knowledge management, window control, screenshots, system cleanup, launching, and package management — nothing more, nothing less.
1. Claude Desktop (with Cowork)
The AI assistant, now living natively on your Mac. The Cowork feature is the real story here: it turns Claude into something closer to a colleague than a chatbot, able to work alongside you on documents, research, and writing tasks.
Why it's on the list: If you do any kind of text-heavy work — writing, summarizing, brainstorming — having Claude one click away beats switching to a browser tab every time.
2. Obsidian (+ AI plugins)
A Markdown-based note app that stores everything as plain local files. Pair it with an AI plugin (like the Claudian plugin) and your notes become a searchable, AI-augmented second brain.
Why it's on the list: Your knowledge stays yours — local files, no lock-in — while AI makes retrieval and synthesis dramatically faster. The 20-minutes-to-second-brain promise is real if you actually write things down.
3. Chrome
Yes, Safari is more power-efficient. But Chrome wins on ecosystem: extensions, dev tools, and seamless Gmail/Google Workspace integration.
Why it's on the list: If your work lives in Google's ecosystem, fighting Safari's quirks isn't worth the battery savings. Pick the browser that matches your workflow.
4. Rectangle
Free, open-source window management. Drag windows to screen edges to snap them into halves, thirds, or quarters — plus keyboard shortcuts for everything.
Why it's on the list: macOS's built-in window tiling is still catching up. Rectangle is lightweight, free, and instantly makes multitasking on a 13" screen bearable.
5. iShot
A clean, free screenshot and screen-recording tool. The rounded-corner screenshots alone make your docs and tweets look 10x more professional.
Why it's on the list: macOS screenshots are fine; iShot makes them beautiful — annotations, rounded corners, and quick sharing without opening another editor.
6. Lemon
A junk/cache cleaner for Macs with tight storage. Finds the gigabytes of caches, logs, and leftovers that macOS never cleans up itself.
Why it's on the list: Especially valuable on 256GB machines. Run it monthly and stop wondering where your disk space went.
7. Raycast
A Spotlight replacement: blazing-fast launcher with a calculator, clipboard history, window management, and hundreds of extensions.
Why it's on the list: Clipboard history alone justifies the install — stop losing that thing you copied three copies ago. The extension store turns it into a command center.
8. Homebrew
The package manager for macOS. Install dev tools, CLIs, and even GUI apps with one command. Also the prerequisite for running things like Claude Code and AI agents locally.
Why it's on the list: If you touch the terminal at all, Homebrew is non-negotiable. brew install beats hunting down .dmg files every single time.
The philosophy
Eight apps. No duplicates, no "just in case" installs. Each one replaces either a worse built-in tool or an entire category of clutter.
What's on your must-install list? I'm always looking for app number nine.
