The macOS multi-monitor annoyance

You know the moment.

You're on your main screen, deep in something. You reach for a button near the bottom of a window, a status bar, the edge of a tab, and the Dock teleports onto that screen. It wasn't supposed to move. You didn't ask for it.

macOS shows the Dock on whichever display holds your cursor near the bottom edge. Any UI element low in a window becomes a trigger. The Dock keeps jumping between monitors. Apple gives you no setting to lock it. There has never been one. Every jump is an interruption — you stop, hunt for the right screen, find the icon you wanted, and try to remember what you were doing.

For ten years, multi-monitor Mac users have just lived with the broken workflow.

The fix

One click. Done.

DockSolo pins the macOS Dock to the display of your choice. The native Dock stays untouched, unmodified, just held in place. Open the menu bar icon, pick your screen, close it. The Dock stays on one monitor, forever.

Set and forget

Pick your screen once. DockSolo remembers across reboots and reconnects.

Universal binary for M1, M2, M3, M4, and Intel Macs.

Frequently asked questions

Everything about pinning the macOS Dock.

Why does my Mac Dock keep moving between monitors when I am working?
macOS triggers the Dock on whichever display has your cursor near the bottom edge. Any button, status bar, or UI element low in a window can summon it. It follows the cursor by design, with no Apple setting to lock it. DockSolo blocks that behavior and pins the Dock to the display you choose.
How do I lock the Mac Dock to one screen?
Without a third-party app, you can't. Apple offers no such setting. The closest native workaround is moving the Dock to the left or right side, but it still jumps between screens. DockSolo is the simplest dedicated fix: pick your screen from the menu bar, the Dock stays put.
Does DockSolo work with Apple Silicon (M1, M2, M3, M4)?
Yes. Universal binary that runs natively on Apple Silicon (M1 through M4) and Intel Macs.
Is DockSolo compatible with macOS Sequoia and Tahoe?
Yes. DockSolo is tested on macOS 13 Ventura, 14 Sonoma, 15 Sequoia, and 26 Tahoe. The minimum supported version is macOS 13.
Does it work with Stage Manager?
Yes. DockSolo pins the Dock independently of Stage Manager, Mission Control, Spaces, and fullscreen apps.
Does it work with Sidecar or an iPad as a second display?
Yes. Any display macOS recognizes (built-in, external, Sidecar, AirPlay) is selectable as the Dock's home screen.
What's the difference between DockSolo and DockLock Pro?
DockSolo is a one-time €4.99 purchase with lifetime updates. DockLock Pro is subscription-based. DockSolo does one thing, pinning the Dock, and does it well, without extra features you did not ask for.
Is DockSolo better than DockAnchor (the free open-source app)?
DockAnchor is a great GitHub project. DockSolo offers the same core function plus a signed and notarized installer, a polished menu bar UI, real support, and ongoing updates. If you're comfortable with Homebrew and don't need support, DockAnchor works. For a polished install-and-forget product, choose DockSolo.
Do I need to disable SIP (System Integrity Protection)?
No. DockSolo runs as a standard userland app. SIP, Gatekeeper, and your Mac's security settings stay enabled.
Does it require Accessibility permissions? Why?
Yes. macOS requires Accessibility permission for any app that watches mouse events system-wide. That's how DockSolo detects when your cursor would otherwise trigger the Dock on another display. The permission is requested on first launch.
Will it slow down my Mac?
No. DockSolo uses around 30 MB of RAM and effectively zero CPU at rest. There is no measurable battery impact.
What happens when I disconnect or add a monitor?
DockSolo remembers your preferred screen by display identifier. If that display is connected, the Dock pins to it. If not, it falls back to the main display until your preferred screen returns.
Can I choose which screen the Dock stays on?
Yes. The menu bar menu lists all connected displays. Click the one you want the Dock to live on.
Is it a one-time payment or a subscription?
One-time payment, €4.99 incl. VAT. No subscription, ever.
Do I get free updates forever?
Yes. Lifetime updates are included with your €4.99 purchase. New macOS versions, new features, bug fixes, all free.
