Get back something you copied earlier

Copy something, copy something else, and the first one used to be gone. In macOS Tahoe it is not.

Press ⌘ + Space to open Spotlight, then click the clipboard button to the right of the search field, or press ⌘ + 4. The first time, Spotlight asks for permission to search the clipboard; accept. After that you get a list of what you have copied, and you can type to search it.

To use an item again, click the copy button next to it, or select it and press ⌘ + C; then paste as usual with ⌘ + V.

Bear in mind that everything you copy ends up in that list, sensitive information included. To wipe it, click the More button to the right of the search field and choose Clear History. Since macOS 27, System Settings → Spotlight also lets you choose how long the history is kept: 30 minutes, 8 hours or 7 days.
