1. Introduction to Split Screen

Split Screen is a powerful multitasking feature that allows users to run two applications side by side on their Mac. This functionality has transformed how users engage with their devices, making it easier to compare documents, take notes based on presentations, or manage communications without switching between windows.

What is Split Screen?

Split Screen divides your display into two sections, with each section dedicated to a different application. Users can drag and drop windows to adjust the size, enhancing visibility and workspace efficiency. This capability is particularly beneficial for professionals, students, and anyone who juggles multiple tasks at once.

2. Latest macOS Features

As of 2025, macOS has introduced several exciting features that enhance the Split Screen functionality:

2.1 Stage Manager

Introduced in macOS Ventura, Stage Manager allows users to organize their applications more intuitively. It keeps your desktop uncluttered by presenting the open applications as thumbnails on the side. This feature complements Split Screen by allowing for quick switching between different sets of applications.

2.2 Enhanced Window Management

macOS Monterey and subsequent updates have improved window management capabilities. Users can now:

• Stack windows automatically.
• Use keyboard shortcuts for quicker access to Split Screen.
• Adjust the size and position of windows more fluidly.

2.3 Universal Control

This feature allows users to control multiple Apple devices with a single mouse and keyboard. If you have an iPad alongside your Mac, you can seamlessly drag and drop files between the two while using Split Screen on your Mac.

2.4 Focus Modes

Focus Modes, introduced in macOS Monterey, allow users to minimize distractions by limiting notifications and app access. Coupled with Split Screen, you can create a dedicated workspace for specific tasks, such as work or study, enhancing productivity.

3. Hardware Innovations

With the release of the M2 chips and beyond, Apple has significantly improved the performance of their hardware. The new Macs come with:

3.1 Improved Graphics Performance

The latest M2 and M3 chips feature enhanced GPU capabilities, enabling smoother multitasking and more responsive Split Screen operations. Users can run demanding applications alongside each other without noticeable lag.

3.2 High-Resolution Displays

Many new Mac models, including the MacBook Pro and iMac, now come with Retina Displays or Liquid Retina XDR. These screens offer better color accuracy and resolution, making Split Screen more effective for tasks that require visual precision, such as design or video editing.

3.3 Expanded Memory Options

With support for up to 64GB of unified memory, newer Macs can handle more applications running simultaneously, optimizing the Split Screen experience for users who work with large files or complex software.

4. Setting Up Split Screen

Setting up Split Screen on your Mac is a straightforward process. Here’s how to do it step by step:

Step-by-Step Instructions

1. Open Both Applications:

   • Start by launching the two applications you want to use in Split Screen.

2. Enter Full-Screen Mode:

   • Click the green maximize button in the upper-left corner of one application window. Alternatively, you can use the keyboard shortcut Control + Command + F.

3. Use the Split View Option:

   • Once the first app is in full-screen mode, the other open windows will appear as thumbnails on the right side. Click on the thumbnail of the second app you want to use in Split Screen.

4. Adjust the Window Sizes:

   • You can adjust how much space each application takes up by dragging the vertical divider between the two windows.

5. Exit Split Screen:

   • To exit Split Screen, you can click the green button again on one of the windows, or press Esc on your keyboard.

Example: Using Split Screen for Research and Writing

Imagine you’re writing a report while conducting research. You can have your web browser open on one side and your word processor on the other. This setup allows you to copy information directly from your browser into your document without switching back and forth between apps.
