dockmacos
Don't mark this as a duplicate. Question has been asked several times in several places but it was years ago.
I have two monitors connected. One primary (that has dock at the bottom) and secondary. My monitors aren't mirrored (cloned). Both of them display different stuff but the dock appears just on the primary one.
Is it possible to see my dock (the same dock) on both of them?
I answered a similar question here - cmd-tab behavior on Mavericks with multiple displays
The Task Switcher does follow the Dock. If the Dock is on screen 1, the Task Switcher will appear on screen 1. If the Dock is on screen 3, the Task Switcher will appear on screen 3. Etc.
To make your Dock appear on a screen you can use a couple of methods.
Method 1 - Move your mouse to the bottom of the desired display. Don't stop once you reach the bottom of the display though, try to move it further down, as if you're pushing down on the bottom of the display with your cursor. This action tells the Dock to move to this display. This is temporary however, meaning the Dock will stay on this display until you perform this action on another display or reboot your Mac.
Method 2 - This will change the default starting point for your Dock. In System Preferences > Displays > Arrangement you can drag the menu bar from one display to another in this windows display icons. See the attached picture for reference. This alters the default preference to always show the Dock on the desired display, the one you drag the menu bar to in this preference pane, when you boot and/or login to your user account. You can still use method 1 to temporarily change the Dock's location but upon a reboot it will return to the display specified here.
I Googled and found a solution for the resizing issue. (Source)
Make your application launch via an Apple Script!
Make a script similar to this:
tell application "YOUR APPLICATION NAME"
launch
end tell
tell application "YOUR APPLICATION NAME"
set the bounds of the front window to {0, 22, 800, 1024}
end tell
Save it as "Application"
Put the saved application in your Launch Items instead of the program itself
Additionally you may undock it with Dock Dodger to make this script run silently.

After extensive search, I have not found any solution specifically for the native macOS Dock.
However, not wanting to put up with this nuisance, I configured the third party Contexts app to always be visible and show only icons when not hovered.
I'm more than happy with this solution. The only drawback is that you cannot configure the context sidebar to be in the bottom of the display, like the dock.
