How to Split Your Screen Between Apps Without Any Third-Party Software

3. macOS Split View and Stage Manager

Apple's macOS offers sophisticated native screen splitting capabilities through its Split View feature and the newer Stage Manager functionality introduced in macOS Ventura. Split View allows users to run two applications side-by-side in full-screen mode, creating a distraction-free environment that maximizes focus and productivity. To activate Split View, users can click and hold the green maximize button on any window, then drag it to either side of the screen, where macOS automatically resizes it to occupy exactly half the display. The system then presents Mission Control thumbnails of other open applications, allowing you to select which program should fill the remaining space. This implementation ensures that both applications receive equal screen real estate and remain fully functional without interface compromises. Stage Manager represents Apple's latest evolution in window management, organizing open applications into groups that can be quickly accessed and arranged. This feature automatically arranges windows in overlapping clusters while keeping the most relevant applications prominently displayed. Users can create multiple stages for different projects or workflows, with each stage maintaining its own collection of applications and window arrangements. The system intelligently manages memory and processing resources, ensuring that background stages don't impact the performance of active applications while maintaining quick switching capabilities.
