Here’s exactly how to do split screen on Mac (Apple calls it “Split View”), plus a bit of forum-style context and tips.

How to Do Split Screen on Mac

Quick Scoop

If you just want the basics:

  1. Open the two apps or windows you want to see side by side.
  2. On the first window, hover over the green traffic-light button in the top-left corner.
  3. Click “Tile Window to Left of Screen” or “Tile Window to Right of Screen.”
  4. On the other side of the screen, click the second window you want to use.

That’s it — you’re in Split View with both apps sharing the screen.

Step‑by‑Step: Split View on Modern macOS (Monterey, Ventura, Sonoma,

Sequoia)

Use this if your Mac is reasonably up to date (last few years).

A. Enter split screen

  1. Prepare your apps
    • Open both apps or browser windows you want (for example, Safari and Notes).
  2. Choose the first side
    • Move your pointer over the green button in the upper-left corner of the first window.
    • Wait a moment; a small menu appears with options like:
      • “Tile Window to Left of Screen”
      • “Tile Window to Right of Screen”
  3. Tile the first window
    • Click either “Tile Window to Left of Screen” or “Tile Window to Right of Screen.”
    • The window jumps to that side and fills half the display.
  4. Pick the second window
    • On the empty half of the screen, macOS shows thumbnails of other open windows.
    • Click the one you want.
    • Now both apps share the screen in Split View.

B. Adjust size and sides

  • Move your pointer to the vertical divider between the two windows.
  • When the pointer becomes a double‑headed arrow, click and drag:
    • Drag left to give more space to the right window.
    • Drag right to give more space to the left window.

To swap sides :

  • Click and drag the title bar of one app all the way to the other side.
  • Release when you see it “snap” into place.

C. Exit split screen

You have a couple of options:

  • Move your pointer to the top of the screen to reveal the window buttons, then:
    • Click the green button on ONE of the windows to take that app back to normal, leaving the other in full screen.
  • Or open Mission Control (F3 or swipe up with three/four fingers), then:
    • Hover over the Split View space at the top.
    • Click the small x on it to close the space; the apps return to their own windows.

Using Split Screen with Mission Control

If you like seeing a bird’s‑eye view first, you can set up Split View from Mission Control:

  1. Open the first app and press F3 or swipe up with three/four fingers to enter Mission Control.
  2. Drag that app’s window to the top of the screen into the area where Spaces (desktops) are.
  3. Then drag a second app’s window onto that same space thumbnail.
  4. Click that space to jump into Split View with both apps there.

This feels a bit “power‑user,” but once you get used to it, it’s handy when you have lots of windows open.

Keyboard‑Friendly Ways (Semi‑Shortcut)

There isn’t a single one‑key “split screen” shortcut, but you can get close:

  • Press Control + Command + F on a window to make it full screen.
  • Open Mission Control (F3 or gesture).
  • Drag another app into that full‑screen window’s space at the top to create a Split View pair.

Some power users also create custom keyboard shortcuts in System Settings → Keyboard → Keyboard Shortcuts → App Shortcuts to trigger menu items like “Replace Tiled Window.”

Mini Section: Old Habits vs. Split View

On forums, you’ll often see two types of Mac users:

  • The “manual resize” crowd
    • They just drag windows by hand and don’t bother with Split View.
    • Works fine if you only need a rough side‑by‑side layout.
  • The “Split View all day” crowd
    • Loves the clean, distraction‑free look with two locked apps.
    • Great for writing with a browser on one side, email + calendar, or coding + docs.

Both are valid; Split View just automates the layout and keeps things tidy.

Mini Section: Common “Why Isn’t It Working?” Issues

If Split View doesn’t appear or seems missing:

  • Check that you’re not using an app that doesn’t support Split View (some utilities and older apps).
  • Make sure your Mac isn’t in Screen Mirroring mode to some unusual setup where resolutions get odd.
  • Try toggling full screen off and on with the green button, then hovering again.

If absolutely nothing works, a quick restart plus running the latest macOS version usually fixes random UI glitches.

Trending Context: Why People Still Ask This in 2026

Even in 2026, “how to do split screen on Mac” keeps popping up in searches and forums because:

  • Apple has slowly tweaked the UI (hover vs. click on the green button, changes in System Settings), so older tutorials can be slightly off.
  • Many Windows switchers expect “snap” behavior and don’t realize macOS uses Split View and Spaces instead.
  • Remote work and hybrid setups mean more people are juggling chat, meetings, and docs — making split screen suddenly important.

A typical forum post looks like:

“First Mac, trying to do split screen like on Windows 11. I keep hitting the green button and everything just goes full screen instead. What am I missing?”

And the usual answer is essentially: “Don’t click, hover the green button, then choose Tile Left/Right.”

Mini How‑To: Split Screen with Safari and Notes (Example)

If you want a quick real‑world setup:

  1. Open Safari and Notes.
  2. Hover over the green button on Safari → choose “Tile Window to Left of Screen.”
  3. On the right, click Notes.
  4. Drag the divider to give Safari a bit more room for reading and leave Notes narrower for writing.

You now have a perfect research‑and‑notes split view, great for studying, coding tutorials, or work documentation.
