macOS Popover
A macOS Popover is a small surface that appears for a short time. An arrow points back to the control or content that opened it.
Another example
Clicking a calendar event opens a small editor beside it. Clicking elsewhere saves and closes the popover.
Main parts
- 01Trigger
- 02Anchored or modal surface

Use it when
Use it for a short task that stands on its own. Keep it clearly tied to the item that opened it.
Do not use it when
Do not put a long form, many screens, or easy-to-lose edits in a popover. Use a window or sheet instead.
Name used in code
AppKit NSPopover / SwiftUI popover Before you ship
Check the supported macOS versions and AppKit or SwiftUI integration. Check standard focus and keyboard behavior. Also check VoiceOver, Full Keyboard Access, window resizing, and multi-window state. When needed, check restore, localization, and reduced motion.
Outcome: Apply or review macOS Popover in a native macOS app without breaking platform rules. User context: Clicking a calendar event opens a small editor beside it. Clicking elsewhere saves and closes the popover. macOS concept or control: macOS Popover. Why it fits: Use it for a short task that stands on its own. Keep it clearly tied to the item that opened it. Do not use it when: Do not put a long form, many screens, or easy-to-lose edits in a popover. Use a window or sheet instead. Platform requirements: List the supported macOS versions. Say whether AppKit or SwiftUI owns each part and how they connect. Define window, menu, focus, keyboard, saved state, restore, and multi-window behavior. Platform accessibility and resilience: Use the right accessibility APIs. Check VoiceOver and Full Keyboard Access. Support localization, contrast, and reduced motion when needed. Keep user state after a relaunch. Acceptance criteria: Check the behavior on supported macOS versions with a keyboard and VoiceOver. Window resizing, focus, state restore, and AppKit or SwiftUI integration work in the normal macOS way. Evidence and limits (evidence boundary): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Supported macOS versions, AppKit or SwiftUI structure, and window model. Also confirm sandbox and entitlement limits, save rules, and the accessibility goal.
