How do I clear the clipboard on a Mac?

Fastest: copy something harmless, like a single space — the clipboard only holds one item, so the old one is gone. To truly empty it, run 'pbcopy < /dev/null' in Terminal. Restarting the Mac also clears it.

Does the Mac clipboard clear itself?

Only on restart or when overwritten by the next copy. macOS does not auto-expire clipboard contents on a timer — though items copied from password managers usually self-clear because those apps clear or mark them.

How to Clear the Clipboard on a Mac

Q: Does the Mac clipboard clear itself?

Only on restart or when overwritten by the next copy. macOS does not auto-expire clipboard contents on a timer — though items copied from password managers usually self-clear because those apps clear or mark them.

You copied a password from a text file, an API key, or someone's personal details — and now it's sitting on your clipboard waiting to be pasted into the wrong window. Clearing it takes two seconds; here is every way, plus what actually needs clearing when a clipboard manager is involved.

Method 1: Overwrite it (fastest)

The macOS clipboard holds exactly one item. Copy anything harmless — select a single space in any document and press ⌘C — and the sensitive item is gone. This is the whole trick; there's no cache of previous items in stock macOS. (Full background: how the Mac clipboard actually works.)

Method 2: Truly empty it with Terminal

Overwriting leaves something on the clipboard. To leave nothing:

pbcopy < /dev/null

This pipes zero bytes into the pasteboard, leaving it genuinely empty — Finder's Edit → Show Clipboard will show nothing. Handy in scripts too (e.g., a shell alias like alias clearclip='pbcopy < /dev/null').

Method 3: Restart

The pasteboard lives in memory; a restart always clears it. Overkill on its own, but worth knowing that sensitive clipboard data doesn't survive a reboot.

What about Universal Clipboard?

If Handoff is on, a copy made on your iPhone can sit on your Mac's clipboard (and vice versa) for a couple of minutes. Overwriting on either device replaces it everywhere; Universal Clipboard items also expire on their own after a short window.

If you use a clipboard manager: clear the history too

Clearing the system clipboard doesn't touch a history tool's saved items — that's their whole purpose. Two things worth doing:

Spot-delete or clear: in Vee, delete individual items from the popup or clear the whole history from settings in one action.
Trust the guard rails: passwords copied from a password manager shouldn't be in history at all — good tools skip items flagged as concealed. If you copied a secret from somewhere unflagged (a text file, an email), that's the case where a manual clear matters. More on this in are clipboard managers safe?

Frequently asked questions

Can other apps read my clipboard right now?

Technically yes — pasting requires it. Since macOS 15.4, apps reading the pasteboard in the background without a paste trigger a permission prompt, so surprise readers are far more visible than they used to be.

Is there a keyboard shortcut to clear the clipboard?

Not built in. The space-overwrite trick is the de facto shortcut, or bind the pbcopy command to a hotkey with Shortcuts/Automator.
