How to make Dock, Menu Bar, and App Switcher appear on the screen with my mouse cursor on Mac?

On macOS there isn't a built-in way to always have the Dock, Menu Bar, and App Switcher follow your mouse across multiple screens - the behavior is inconsistent. If you want that level of control, you'll need a helper app. One good and the only option is DockLock Plus (available in the Mac App Store). It has a Dock Follows Mouse feature that moves the Dock and App Switcher to whichever display your cursor is on, and also a Dock Follows Active Window mode if you'd rather tie it to the app you're working in. You can also lock the Dock to a specific screen so it never moves, or set up automations through Shortcuts to make the Dock move exactly where and when you want it. Since the App Switcher always follows the Dock's location, controlling the Dock this way also gives you predictable control over the App Switcher. The only requirements are that Displays have separate Spaces must be enabled in macOS settings, and that the Dock is positioned at the bottom of the screen.
