Recover something you copied earlier on macOS

You had something important on the clipboard — a passage you wrote, a confirmation number, a long URL — and you copied something else on top of it. The original is gone. macOS replaces clipboard contents with no undo and no second buffer.

Two paths

Native macOS. Honest answer: you can’t recover an overwritten clipboard with stock macOS. There’s a single clipboard slot and a “Show Clipboard” view in the Finder’s Edit menu that always shows whichever item is currently there. If you copied over the text you needed, the only way back is to find the original source and copy it again. iCloud Universal Clipboard doesn’t keep a history either — it just syncs the current item between your devices.

Sometimes you get lucky:

• If the original was in a browser tab or document you haven’t closed, scroll back, find it, and re-copy.
• Some apps (Notes, Pages) have undo history that may still contain the text if you typed it there.
• For text fields where you typed something, ⌘Z often brings it back.

But once the source is gone, the copy is gone too.

Going forward — keep a real history

Perch. A clipboard manager that records everything you copy. Once it’s installed, the “I just overwrote something important” problem stops happening — you can scroll back to any clip from the last 90 days (or forever, if you set retention that way).

1. Install Perch.
2. Copy normally with ⌘C — Perch records each copy automatically.
3. When you need an earlier copy, press ⌘⇧V to open Perch's history.
4. Scroll or search for the item, then press ↩ to paste it.

That’s the whole flow. There’s nothing to remember to enable per-copy — Perch captures in the background, and pasting goes through the same ⌘V habit you already have, or via the Perch picker when you need an older item.

One honest note

Perch can only recover copies it actually captured. If you install it after losing the text, it doesn’t help with that specific loss — clipboard history isn’t retroactive on any platform. But it does mean today is the last day this particular kind of mistake will cost you anything, because every copy from now on is preserved.
