macOS Focus Modes silence notifications, but they don't launch your apps, restore your tabs, or set up your workspace. When you combine Focus Modes with a context manager like Ikuna, activating "Deep Writing" doesn't just block distractions

Your Mac defaults to distraction mode because it's configured for app switching, not focused work. Notifications, irrelevant apps, open browser tabs, no project boundaries: the default macOS setup optimizes for access, not focus. Fixing it requires two changes: silencing the interruption layer and structuring your workspace layer. The interruption layer is what pulls your attention away (notifications, badges, sounds). The workspace layer is what's already open when you sit down to work. Most people fix the first and ignore the second. That's why Do Not Disturb alone doesn't work.

The term "context manager" describes a new category of Mac productivity software that goes beyond traditional window management. While Rectangle moves windows and BetterStage saves workspace layouts, a context manager like Ikuna captures the full cognitive environment of a project: which apps you need, which tabs are open, and which system state supports that specific type of work.
