Master Mac Split Screen: Run Two Apps Side-by-Side

Master Mac Split Screen: Run Two Apps Side-by-Side for Unstoppable Productivity

Tired of constantly switching between apps? Mac Split View is your answer—a built-in feature that lets you run two full-screen apps simultaneously on a single display, giving you a focused workspace for parallel work without the window management headache.

What is Mac Split View?

Split View is macOS’s window management feature that displays two full-screen applications side-by-side, each occupying a perfect 50/50 division of your screen. Unlike simply resizing windows manually, Split View snaps apps into dedicated full-screen spaces while keeping both visible at all times. This is different from older macOS features like Mission Control or Exposé—it creates a seamless multitasking environment designed for focused parallel work.

Introduced in OS X El Capitan (10.11) back in 2015, Split View remains available in all current macOS versions, including the latest macOS Tahoe (version 26 as of August 2026). Whether you’re running an Apple Silicon Mac or an older Intel model, Split View works identically on both architectures.

Why Use This Feature?

• Research and Reference: View a reference document in one half while writing or composing in the other—perfect for comparing sources, checking facts, or drafting emails.
• Communication and Collaboration: Keep Mail or Messages open on one side while working on documents on the other, so you never miss important messages while staying focused.
• Content Creation: Place reference images, notes, or outline documents alongside your primary work for seamless creative flow.
• Multi-App Workflow: Safari, Mail, Notes, and hundreds of other third-party apps all support Split View, giving you complete flexibility to choose which two apps work best for your task.

What You Should Know Before Using Split View

• Full-Screen Requirement: Split View only works when both apps are in full-screen mode. You cannot use Split View with windowed apps side-by-side in your regular desktop view.
• Multiple Display Setup: If you use multiple external displays, you’ll need to enable ‘Displays have separate Spaces’ in System Preferences > Mission Control to use Split View on displays other than your primary one. Without this setting enabled, windows can sit half on each display instead.
• Available on Compatible Macs: Split View requires OS X El Capitan (10.11) or later. All modern Macs—whether running Ventura, Sonoma, Sequoia, or the latest Tahoe—support this feature.
• Sequoia’s Bonus Feature: If you’re running macOS Sequoia or later, you can also drag apps to screen edges for automatic window snapping—a newer convenience feature that works alongside traditional Split View.

How to Activate Split View on Your Mac — Step by Step

Step 1: Open Your First App and Enter Full-Screen Mode

Launch the first app you want to use (for example, Safari or Mail). In the top-left corner of the app window, you’ll see three buttons: the red close button, yellow minimize button, and green maximize button. Click the green maximize button—or press Control+Command+F—to enter full-screen mode.

Step 2: Reveal the Split View Menu

Now hover your cursor over the green maximize button (in the top-left corner) without clicking. A menu will appear showing available apps you can use for Split View. Alternatively, press Control+Up Arrow to bring up this same menu.

Step 3: Select Your Second App

From the menu, click the second app you want to view alongside the first (for example, Notes or Messages). It will instantly fill the right side of your screen in full-screen mode. Your first app now occupies the left half, and your second app occupies the right half—both fully visible and interactive.

Step 4: Work Across Both Apps

Click on either side of the screen to make that app active and use it normally. You can type, scroll, and interact with both apps as if they were each at full screen. Your workflow remains uninterrupted.

To Exit Split View:

Click the green maximize button (or press Control+Command+F) on either side of the screen, and select ‘Exit Full Screen’ from the menu. This returns you to your normal desktop view with windowed apps.

Mac Split View is a powerful, built-in feature that transforms how you work—turning constant app switching into seamless parallel productivity. Once you experience the focused workflow of having two full-screen apps side-by-side, you’ll wonder how you ever worked without it.
