Optimizing Single-Screen Productivity on macOS

I transitioned from a three-monitor setup (laptop + dual 27” displays) to single-screen productivity to reduce context switching and eliminate notification distractions. The multi-screen configuration, while seemingly efficient, created cognitive overhead through constant peripheral interruptions.

Implementation Strategy

System Configuration

1. Static Desktop Management: Disable “Automatically rearrange Spaces based on recent use” in System Settings > Desktop & Dock
2. Visual Dock Segmentation: Install vertical-bar.app separators (9 instances) to create logical application groups
3. Application Binding: Assign each application to dedicated spaces via right-click context menu
4. Animation Optimization: Enable “Reduce motion” in Accessibility settings for faster transitions
5. Keyboard Navigation: Configure Option + [1-9] shortcuts for instant space switching via Mission Control settings

Workflow Benefits

This configuration enforces single-tasking by design, eliminating visual distractions while maintaining rapid application access through muscle memory keyboard shortcuts. The systematic approach reduces decision fatigue and improves sustained focus on primary tasks.
