WideSplit for Mac
Split your ultrawide monitor into two or three screens
WideSplit turns one ultrawide monitor into two or three separate screens that macOS knows. Each one has its own Spaces, its own full-screen apps and its own place in the share picker.
One monitor, separate screens
Choose “Do the magic” from the WideSplit icon in the menu bar and your monitor becomes three screens side by side. Other layouts put two screens side by side, or two or three on top of each other.
Drag the line between two screens to change their widths. When you let go, the split comes back with the new widths and the layout is saved. In Settings you can also pick a standard width, a half, a third, or type the width in pixels.
Full screen on one screen, not the whole monitor
An app in full screen fills one screen. The screens next to it stay as they were.
Each screen has its own Spaces — add desktops to any of them in Mission Control. The Dock is there on each screen, and windows move from one screen to the next as they would between two monitors.
Safe to try
A new layout starts as a trial. Keep it, or your monitor returns to full screen by itself.
⌃⌥⌘P returns your monitor to full screen at any time. When copy-protected video plays, the split steps aside and comes back by itself when you close the player.
Questions
Can you split an ultrawide monitor into two monitors on a Mac?
Yes. WideSplit splits one ultrawide into two or three screens that macOS knows. It's still one physical monitor and one cable — you get separate screens on it.
Is this the same as snapping windows?
No. Snapping arranges windows on one screen. WideSplit gives you separate screens, so full screen, Spaces and the share picker work screen by screen.
Which monitors does it work with?
WideSplit is made for wide monitors. During the beta we're learning how it runs on each model, so please tell us about yours.
What do I need?
A Mac with Apple Silicon, macOS 26 or later, and a wide monitor. To split the screen, WideSplit needs two macOS permissions — Screen Recording and Accessibility. The Permissions page lists what each one allows.
Is it free?
