WideSplit for Mac
One external monitor on your MacBook. Several screens on it.
WideSplit splits one wide monitor into two or three separate screens that macOS knows. It doesn't add a second monitor — it makes more of the one your MacBook already drives.
What you get, honestly
Still one cable and one physical monitor. On it, two or three screens, each with its own Spaces and its own full-screen apps.
Put code on one screen, a browser on the next and a call on the third. No extra adapter, no extra cable.
Your MacBook screen stays as it is
Split the external monitor and keep the MacBook open next to it. Its built-in screen stays an ordinary desktop, and the pointer moves between them.
When you return to full screen, the screens go back to where they were. No external monitor with you? WideSplit can split the MacBook's own screen too.
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.
Questions
How many external monitors does a MacBook Air with M1 or M2 support?
Officially, one external display. WideSplit doesn't change that — it gives you several screens on that one display.
Will this give me a second physical monitor?
No. It's still one monitor. WideSplit splits it into separate screens; it doesn't add a monitor your Mac can't drive.
Do I need a wide monitor?
A wide monitor gives each screen enough room. On a narrower monitor the screens are narrower too.
What do I need?
A Mac with Apple Silicon, macOS 26 or later, and a wide monitor if you want screens side by side. To split the screen, WideSplit needs two macOS permissions: Screen Recording and Accessibility. The Permissions page lists what each one allows.
