A protected player takes over? The split steps aside.
Open a protected player and WideSplit returns to the full screen. Close it and your layout comes back by itself. No menu, no shortcut.
WideSplit for Mac
One monitor.
Multiple screens.
One click.
Turn your ultrawide into three real displays. Each with its own Spaces, its own full-screen apps and its own share button. No cables. No second monitor.
macOS 26 or later · Apple Silicon · Free beta
Click the menu bar icon. That's it.
Layouts
Three across.
Real displays macOS understands. Not a window trick.

Sizes
Drag the line.
Screens follow.
Grab a divider and slide it. Widths snap to presets or go pixel-exact. Try it — the mock below is live.

Spaces
Every screen gets its own Spaces.
Each screen is a real display to macOS. Add desktops on any of them, full-screen a call on the left and keep working on the right — the others do not move, exactly like on three monitors.
Three-finger swipe on the middle screen.
Under load (optional)
Can step aside under load.
Comes back on its own.
Something heavy hogs the machine? Switch this on in Settings and WideSplit returns to the full screen instead of adding to the slowdown. It tries the split again by itself, and waits longer each time the Mac is still too busy.
Running smoothly.
And the rest
Built for the day, not the demo.
⌃⌥⌘←
Window manager included.
Halves, quarters, thirds, next screen, undo. Shortcuts are off until you switch them on.
⌃ ⌥ ⌘ P
One key. Whole monitor back.
Returning to the full screen is never locked, never gated, never slow to reach.
Remembers each setup.
Set the layout once for a set of displays. Plug in there again and it comes back.
Status at a glance.
One icon in the menu bar. Grey off, green on, amber while it changes. Health in plain words.

English, Polish, Spanish, Chinese and Japanese — in the app and on this site. The app follows your Mac's language, and you can choose another in the app.
Privacy
Nothing leaves your Mac.
WideSplit draws your screens. It does not record them.
- Frames never touch disk or network.The picture goes from your Mac to your Mac. Nowhere else.
- Three permissions, each explained.Accessibility for WideSplit and its window manager, and Screen Recording to draw your screens. WideSplit needs all three; you can revoke them any time.
- One website, nothing else.Once a day a small update file from our site. The released version adds an online licence check. No analytics, no telemetry.
- Check it yourself. Don’t take our word.A page with the commands that measure what the running binary really does — the event taps, the network symbols, the entitlements.
Beta
The beta starts soon.
Join the waiting list and we will write to you when the beta is ready to download. It's a free beta — no card, no account.

About the beta
The WideSplit beta is free to use and not finished yet. Some things will break. When they do, we're sorry — and we'd like to hear about it.
What does “beta” mean here?
WideSplit has run on far fewer Macs and monitors than it will meet out there. Expect rough edges, and expect things to change from one build to the next. To turn the split off, choose Stop the magic in the WideSplit menu or press ⌃⌥⌘S. If your screen ever gets stuck, press ⌃⌥⌘P — WideSplit returns your monitor to full screen.
How long does a beta build work?
Each beta build works for a limited time. When a newer build is out, Check for Updates… in the WideSplit menu brings it. If a build stops before you update, WideSplit puts your monitor back to full screen and stops splitting; ⌃⌥⌘P still works. Your settings stay on your Mac either way.
Is it free?
The beta is free — no account, no card. It may contain bugs; we're sorry for them, and we'd like to hear about them — the next question says how.
What do I need?
A Mac with Apple Silicon, macOS 26 or later, and a wide monitor. To split the screen, WideSplit needs two kinds of macOS permission — Screen Recording and Accessibility — and explains each one before macOS asks. The Permissions page lists what each one allows.
What doesn't work yet?
- Copy-protected video: while a player with protected video is open, the picture may go black or the split steps aside; it comes back by itself when you close the player.
- Notifications: while the screen is split, macOS may hold back notification banners until you allow them in System Settings. WideSplit shows you where.
- Known problems in the current build are listed on GitHub, updated with every build.
How do I report a problem?
Whichever way suits you:
- GitHub — open an issue at github.com/WideSplit/feedback. It's public, so others can add to it and follow the fix. Search first: it may already be there.
- Email — [email protected], for anything private, or if you don't use GitHub.
It helps most if you tell us your WideSplit version, macOS version and Mac model, your monitors and layout, whether the split was on, and the steps that lead to the problem.
How do I ask for a feature?
The same two ways — a feature request on GitHub, or an email. Tell us what you're trying to do and what gets in the way; the problem helps us more than a finished design. We can't build every request, and we don't promise dates.
What's in a report, and who sees it?
Only what you send. WideSplit sends no telemetry and no crash reports; the only thing it contacts on its own is our update site, once a day, to check for a new build — the Privacy page names it. You see every report before it's sent. Reports and logs can include your macOS user name, identifiers of your monitors and the names of apps and windows you had open — send them by email, never in a public issue. We use them only to fix WideSplit.
When will I hear back?
We read everything. WideSplit is made by a small team, so a reply can take a few days, and there's no guaranteed response time during the beta. On GitHub, an issue's status shows where it stands.
How do I remove WideSplit?
WideSplit menu › Revoke permissions & uninstall… turns the split off, removes WideSplit's permissions as far as macOS allows, and moves the app to the Trash. If an entry stays in System Settings › Privacy & Security, switch it off there.
Thanks for trying WideSplit.
