Switching between windows in Safari only works when multiple tabs are open

Hi there! It sounds like you’ve run into a frustrating and oddly specific issue with Safari. While macOS generally supports switching between app windows using Command + `, Safari seems to behave differently when there’s only one tab open—something that’s unfortunately been noted by a few other users as well. This quirk appears to persist even through updates, including the latest Sequoia 15.5, and may be tied to how Safari handles its window and tab management internally. While there’s no official fix from Apple yet, one possible workaround is to keep at least two tabs open in each Safari window, though I understand that’s not ideal. Hopefully, a future update will resolve this inconsistency.
