When two Mac windows have the same title, the title is no longer an identifier. Treat each match as a candidate and require a second clue before you focus it or make a change.

Choose a second clue from the source

Useful clues include the application, file path, repository root, browser profile, account avatar, environment banner, client name, or a distinctive part of the visible content. Prefer a clue supplied by the source application over a switcher’s list position.

Duplicate title Better verification
Dashboard account and environment
README.md repository root
Untitled visible opening line and app
Inbox service and signed-in identity

A thumbnail can help, but similar pages and low-resolution previews can still look alike.

Improve the title where possible

Rename the document, Chrome window, terminal session, or project so the identity appears in future lists. Keep the label stable: “API staging logs” is more useful than “Window 2.” A project group can narrow candidates further, but membership is still not proof that the live content has not changed.

Stop when identity remains ambiguous

Do not select the first result or the most recently used candidate when the next action is destructive or externally visible. Bring each window forward for inspection, or return to the source application’s own document list.

Wallo’s window-targeting principle rejects ambiguous matches instead of focusing a guessed window. That boundary matters because a system window ID, title, and document metadata can change as applications recreate their windows.
