On Windows, Chrome registers each profile as its own taskbar entry, so a pinned Chrome becomes the first profile you open and further profiles appear beside it. macOS has no equivalent, so the Dock shows one Chrome.

Not with Apple's Dock: macOS keeps a single Dock that jumps to whichever display you push the cursor into, and there is no setting for one per screen. Superdock can put a dock on every display at the same time, and can show on each dock only the apps that have windows on that screen.

Because the Tahoe Dock floats as a Liquid Glass panel and no longer claims a strip of the screen, so a window zoomed to full height now extends behind it. Apple offers no toggle.

Not by itself: hovering a Dock icon shows the app's name and nothing else. Two apps add Windows-style thumbnails.

Because Command-Tab activates an app, not a window, and macOS considers a minimized window to be parked in the Dock rather than part of the app's visible set. Holding Option while releasing Command restores one minimized window; a window switcher such as Superdock's lists every window, minimized ones included, so you pick the one you want.

For two windows, Command-Backtick. For more, or for windows spread across profiles, the fastest path is a Dock tile per profile: one click opens the right profile's windows, right-click lists only them, and Option-Tab shows every Chrome window with a thumbnail labelled by profile.

Not with Apple's Dock; the glass beside the last icon does nothing. Superdock gives each end of the dock an action you choose: Show Desktop, Mission Control, Stage Manager or nothing.

Press Command and the backtick key to cycle the windows of the app you are in. Neither that nor App Exposé shows minimized windows, which is the usual complaint.

Because macOS has only one Dock and moves it between displays rather than showing one per screen. There is no Apple setting for a dock on each monitor.

Because the Dock activates an application, not a window. What the click does, the four native ways to reach one window, and where each stops working.

Command and backtick is the real answer and it works. Here are its three genuine limits, and the case where identical windows defeat it.

Because the Dock gives one tile per process and every Chrome profile runs in the same process. Four workarounds, and what each really costs.

Hold Option while releasing Command-Tab and macOS restores one minimized window. Why it ignores them otherwise, and what to do with several.

Drag it to the right of the divider, then sort by Date Added so the newest file is first. Why it vanished, and the two things that undo it.

macOS gives you a shortcut, a swipe and a hot corner, but nothing to click. What each workaround costs, and the one option that is a real target.

One Terminal command adds a blank space to the Dock. The command, what each part does, how to remove a spacer, and the narrow variant.
