Activity Monitor 1.9.1
Activity Monitor 1.9.1 improves the title bar and makes process search fit smaller windows.
Window and toolbar improvements
- Restored the familiar metric tab styling, with icons and labels when space permits and all six icons in narrow windows.
- Improved width budgeting so tab labels and additional toolbar actions remain visible at smaller sizes.
- Restored the top-right controls and grouped Light, Dark, and System appearance selector.
- Matched the title bar to the window background in light and dark appearances and corrected tab alignment.
- Clipped scrolling content below the title bar so charts and process rows cannot overlap window controls.
Process search
- Kept process controls in one row, with an inline native search field when space permits.
- Added an expandable search button for narrow windows. Active searches stay visible when resizing.
- Command-K focuses search; Escape clears the query and dismisses an empty compact search field.
- Preserved the existing process-list and overview scrolling behavior.
