Why does my Mac Dock only show on one monitor?

macOS has a single Dock. Apple's guide says that with Displays have separate Spaces turned on in System Settings, Desktop & Dock, the Dock is available on all displays. Users in an Apple Support Communities thread report that in practice it moves to the screen you're using and doesn't stay visible on two screens at once, though that's a user report, not Apple's documentation. With the setting off, the Dock stays on the main display.

Does Displays have separate Spaces put the Dock on all screens?

Apple's guide says the Dock becomes available on all displays when the setting is on. In one Apple Support Communities thread, users say it moved to one screen at a time for them, and only with displays side by side and the Dock at the bottom. That's a single forum report, so your results may differ. The setting must stay on for Split View on other displays or Stage Manager.

How do I put a Moor dock on every monitor?

Press Control-Option-E to edit your docks, open the Placement menu in the toolbar and choose All displays. Moor shows one copy of the dock per display and sizes each copy to its screen. To make every copy the same size, open the dock in Settings, Docks and turn on Same size on every display. Press Done when you're finished.

What does All displays, outer edges only do in Moor?

It puts a copy of the dock on each display but skips edges that two displays share. For example, with two monitors side by side and docks on the left, the right monitor's left edge borders the other screen, so it gets no dock. This keeps docks out of the gap your pointer crosses when you move between screens.

Can each monitor have a different dock in Moor?

Yes. Use separate Moor docks and set each one to A specific display on its page in Settings, Docks. Each dock keeps its own items and theme. Profiles decide which docks are on screen, and the Monitor setups option in Settings, Automation can switch profiles automatically when you connect or disconnect displays.

Mac Dock on Every Monitor: Why One Dock and How to Fix It

Why macOS shows only one Dock

As one MacRumors forum member put it, unlike the menu bar, which shows on every screen, there is only one Dock, and it is set to show on the primary display.

Apple's wording here is worth reading closely. The setting that matters is Displays have separate Spaces, near the bottom of System Settings → Desktop & Dock under Mission Control. According to Apple's Mac User Guide, when it's on "the Dock is available on all displays," and when it's off the Dock appears only on the main display.

"Available" is the key word. In an Apple Support Communities thread, users report that you cannot have the Dock constantly visible on more than one display at a time. By those reports, what you get is a Dock that moves to one screen at a time.

Before you turn that toggle off, know that Apple says it must be on to use Split View on your other displays or to use Stage Manager.

What you can do without extra apps

Goal	Built-in setting	Limit
Keep the Dock on the main display only	Displays have separate Spaces off (Apple)	No Split View on other displays, no Stage Manager (per Apple)
Let the Dock move to another screen	Displays have separate Spaces on (Apple)	Not documented by Apple. Users in one forum thread report it showed on one screen at a time, and only with displays side by side and the Dock at the bottom; your results may differ

On that second row, users in the same thread say only a horizontal display layout combined with the Bottom position let the Dock move to whichever screen's bottom edge they pushed the pointer to, after a short delay. With displays stacked one above the other and the Dock on the left or right, it stayed on the main display. This comes from a single forum thread, not Apple's documentation, so results may differ with your macOS version and arrangement.

Third-party apps for multi-display docks

Third-party apps work around the one-Dock limit, either by drawing their own docks or by managing Apple's. Here is what each one's listing or a published review says. The sources below don't confirm macOS 26 (Tahoe) support for most of these apps (DockApp's site is the one that names macOS 26), so if you're on macOS 26, check the linked page before buying. Prices and requirements can change too.

App	What it does across displays	Details from the source
DockLock Plus	Adds Dock Follows Mouse and Dock Follows Active Window to Apple's Dock	The DockLock Lite listing says it needs the Dock at the bottom and Displays have separate Spaces on
DockDoor Pro	Replaces the Dock, with a Dock on every display, fanning folders, widgets and profiles	The base DockDoor is free and open source and adds window previews and Alt+Tab to Apple's Dock
Dockish	Its own dock on every display at once; Independent mode lets each monitor's apps be edited separately	7-day free trial, per Appish
ExtraDock	Multiple floating or fixed docks pinned to any edge, with per-screen position memory	From $27 on its Gumroad page
MultiDock Pro	Separate docks on each connected display	Listing says macOS 15 or later, £4.99 on the Mac App Store; macOS 26 isn't named specifically
ActiveDock 2	A Dock replacement with multi-monitor support	One-time purchase of $19, per AlternativeTo
DockApp	Sends the dock to a chosen display or lets it follow your pointer	Requires macOS 26 and Apple silicon, so it isn't an option on Intel Macs; one-time purchase for up to 3 Macs, listed at $9.99 as an early-bird launch price, so check the maker's site for the current price
HiDock	Changes Apple's Dock size, position and auto-hide based on which displays are connected	From a January 2023 Six Colors review, which notes it can't give different displays different contents
uBar	A taskbar-style replacement some users set up across several displays	Often paired with a window tool to keep windows clear of the bar

MacRumors forum members also mention Sidebar, InfyniDock and TaskBar as docks that can appear on two screens at once. Pick whichever fits your Mac, macOS version and budget.

How Moor does it, step by step

Moor draws its own docks, and each one has its own display setting: one copy per screen, pinned to a single monitor, or following you around. Moor runs on macOS 26 (Tahoe) and later, on Apple silicon and Intel Macs.

New to Moor? On first launch, the setup guide saves your current Dock, then asks which Dock you want: pick Moor's dock. If you already use Moor's docks, start at step 1.

Press Control-Option-E (or choose Edit Docks in the menu bar). The icons wiggle and a toolbar appears above the dock.
Open the Placement menu.
Choose an edge (bottom, left, right or top) and an alignment.
Choose a display option from the table below, such as All displays.
Press Done, or Control-Option-E again.

For more options, click Settings… in the edit toolbar to open the dock's page in Settings → Docks, with a live preview. Use Don't show on to leave out particular displays. Moor sizes each copy to its display, so a vertical monitor gets a dock that fits; turn on Same size on every display to size every copy for the smallest screen instead.

Display option	What it does	Good for
Main display	Always on the main display	One primary screen
Display with the active window	Follows the window you're working in	Keyboard-heavy work
Display with the pointer	Moves to whichever display the pointer is on	Mouse and trackpad users
Outer edge of the desk	Sits on the outside edge of your arrangement	One dock, out of the way
All displays	One copy per display	A true dock on every monitor
All displays, outer edges only	One copy per display, skipping shared edges	Side docks on side-by-side screens
A specific display	Pinned to one monitor	Dedicated docks per screen

Pointer, active window or outer edges?

Display with the pointer puts the dock wherever your hand is. Display with the active window keeps it next to your work even if the pointer has wandered. Both give you one dock that moves, on any edge you choose.

Outer edges matter with side docks. With two monitors side by side and a dock on the left of each, the right monitor's left edge touches the other screen, so its dock sits in the gap your pointer crosses constantly. All displays, outer edges only skips those shared edges. If a dock does sit on a shared edge, Moor fades it instead of sliding it and makes the edge "sticky" so you can still reveal it.

Tips for different docks on different screens

All displays shows the same dock everywhere. For different contents per monitor, make separate Moor docks and set each to A specific display in Settings → Docks. Each dock has its own theme too, so a side dock can use Terminal or Paper while the main one stays Glass. See Docks for every placement option.

Developers: keep apps on a bottom dock on the main screen, and put a slim side dock with the Agents widget on the second screen. It shows Claude Code and Codex sessions and badges the app when an agent needs you.
Store owners: put Shopify or Stripe tiles on the secondary display. Meeting mode hides revenue during calls.
Laptop plus desk: in Settings → Automation → Monitor setups, choose Add Current Setup once on the laptop alone and once at your desk, and pick a profile for each. Moor switches when you plug in or unplug. See Profiles and Automation.

Each dock's Behaviour settings help on busy desks: Automatically hide and show, Hide when an app is fullscreen, Hide while using chosen apps, and Opacity when idle.

Troubleshooting and limits

Apple's Dock still shows next to Moor's. Your active profile is set to Apple's Dock or Both. Switch it to Moor only in Settings → Profiles, or open moor://mode?mode=custom.
A dock won't appear on one screen. Check Don't show on in Settings → Docks, and whether the dock is set to outer edges only.
No badges or minimized windows. Turn on Accessibility in Settings → Permissions, then allow Moor in System Settings → Privacy & Security → Accessibility.
You want the old setup back. Choose menu bar → Manage Profiles → Restore Original Dock…. Quitting Moor also brings Apple's Dock back.

Next steps

Read Docks for placement, behaviour and stacks.
Set up a profile per monitor arrangement with Profiles.
Try All displays first, then switch to pointer or active window if a single moving dock suits you better.
