Flow seamlessly between your displays.
Monitor Flow removes the dead zone between your external monitor and your MacBook — cross anywhere along the edge, not just the overlap.
brew install --cask jab098/tap/monitor-flow
Watch the dead zone disappear.
The dead zone, explained.
macOS only lets the cursor cross where your displays' footprints overlap. Outside that overlap it hits an invisible wall. Monitor Flow bridges the full edge — and maps your crossing onto the other display, right where you'd expect to land.
Display Arranger
Arrange displays the way it should work.
Drag, snap, done — the arranger drives your real macOS arrangement, not a copy of it. Your main display stays pinned, and it warns you before the Dock would wander off.
External Hot Corners
Hot corners, where macOS won't put them.
Apple-style hot corners for your external displays — with explicit modifier keys and power actions macOS doesn't offer: open anything, run a Shortcut, or run a shell command. Configure each display's corners separately and test them with one click.
Display Dimmer
Lights off where you aren't.
Displays you're not using fade down after a delay — kind to OLED panels — and wake the instant your cursor returns. It holds off while media plays or excluded apps are running, and dims all the way to blackout if you want.
And the rest of the toolkit.
Trackpad Haptics
A real tap from the trackpad's actuator every time you cross displays. Three strengths.
Auto-Raise
The window you travel to gets focus when you come to rest — only after a crossing, never mid-drag.
Drags cross too
Mid-drag crossings just work — carry files and windows over without dropping them.
Any number of displays
Every touching edge crosses, and displays sharing an edge each get their own stretch.
Auto-updates
Quiet, secure updates via Sparkle 2 — check, download, and install automatically if you like.
Native & lightweight
A Swift menu bar utility. No Dock icon, no Electron, no subscription — it just runs.
Get Monitor Flow.
Free. No account, no subscription — download and cross.
brew install --cask jab098/tap/monitor-flow
First open
Monitor Flow is signed but not yet Apple-notarized, so macOS Gatekeeper checks in the first time. Two ways past it, once:
Homebrew — no warning at all. Install with
brew install --cask --no-quarantine jab098/tap/monitor-flow
and the app opens straight away.
Downloaded the DMG? After dragging it to Applications, open System Settings ▸ Privacy & Security, scroll down, and click Open Anyway next to Monitor Flow. You only do this once.
One permission
Monitor Flow asks for Accessibility — the permission that lets it watch the cursor and move it across the dead zone. That's the only one it needs, and nothing ever leaves your Mac.
Questions, answered.
Why does it need the Accessibility permission?
Monitor Flow uses a macOS event tap to watch cursor movement and post the synthetic move that carries it across the dead zone. Event taps require the Accessibility permission — it's the only permission the app asks for, and no data leaves your Mac.
Is it really free?
Yes — free to download and use. No account, no subscription, no trial timer.
Which Macs does it support?
Apple Silicon Macs (M1 and newer) running macOS 13 Ventura or later.
Why does macOS warn me when I open it?
The app isn't notarized with an Apple Developer ID yet, so Gatekeeper shows
its standard warning for apps downloaded outside the App Store. Installing via
Homebrew with --no-quarantine skips it entirely; a direct DMG download
gets past it once via System Settings ▸ Privacy & Security ▸
Open Anyway. Updates install quietly after that.
Does it work with three or more displays?
Yes. Every touching edge crosses, and when several displays share one edge Monitor Flow routes each stretch to the right neighbour.
How do updates work?
Built-in via Sparkle — the same updater trusted by hundreds of Mac apps. Check manually, or let it download and install updates automatically.
