Will restarting the pasteboard server delete my clipboard data?

No. Restarting the pasteboard server (`killall pbs`) only refreshes the service that manages your clipboard. It does not erase the current clip. However, since the native clipboard holds only one item at a time, if you lose power or restart your Mac, your clipboard is lost. That's why ClipHistory saves your last 150 clips locally—you never lose important data again.

Can a clipboard manager prevent clipboard crashes on macOS?

A clipboard manager like ClipHistory can't prevent macOS's native clipboard from crashing, but it protects you from *losing data* when it does. ClipHistory stores your full history (150 unpinned plus unlimited pinned clips) 100% locally on your Mac, so even if your clipboard fails, your clips are safe. You can search and paste them with ⌘⇧V.

Is ClipHistory secure if it's not in the cloud?

Yes. ClipHistory is 100% local—no cloud, no servers, no accounts, no data sent anywhere. Your clipboard data never leaves your Mac. It's signed and notarized by Apple, meaning it's been verified for security. At just $19.99 lifetime (one payment, never recurring), you get peace of mind with zero subscription fees.

Can ClipHistory help me organize clips better than the native clipboard?

Absolutely. The native clipboard holds only one item. ClipHistory saves your last 150 unpinned clips plus unlimited pinned ones, auto-detects clip types (URLs, emails, code, colors, phone numbers, images), lets you search instantly with ⌘⇧V, and organize clips on Custom Boards. You can also use AI Transforms to summarize, translate, rewrite, or clean any clip—just bring your own API key from Anthropic, OpenAI, DeepSeek, or Google.

Clipboard Not Working on Mac? 7 Fixes That Actually Work + Prevention Tips

The clipboard is one of macOS's most essential features—until it stops working. Whether you're unable to copy and paste, clips disappear after you close an app, or the clipboard seems stuck, a broken clipboard can grind your workflow to a halt.

Good news: most clipboard issues on Mac are fixable with simple troubleshooting steps. This guide walks you through the most effective solutions, and shows you how to prevent the problem from recurring.

1. Force Restart the Pasteboard Server

The pasteboard server manages your clipboard on macOS. When it crashes or freezes, your clipboard stops responding. Restarting it often fixes the issue immediately.

How to do it:

Open Terminal (Applications > Utilities > Terminal) and paste this command:

killall pbs

Press Enter. The pasteboard server will restart automatically. Try copying and pasting again—this solves the problem in roughly 40% of cases.

2. Clear the Clipboard Cache

A corrupted clipboard cache can cause copy-paste to fail silently. Clearing it forces macOS to rebuild fresh clipboard data.

In Terminal, run:

pbcopy < /dev/null

Then test copying a simple piece of text. If the problem persists, move to Fix #3.

3. Check for macOS Updates

Clipboard bugs are often patched in point updates (e.g., 14.2.1 → 14.2.2). An outdated OS can introduce unexpected clipboard behavior.

Update macOS:

Click the Apple menu > System Settings
Select General > Software Update
Install any available updates and restart

4. Disable and Re-enable the Clipboard in Accessibility Settings

Some macOS versions have a clipboard toggle in Accessibility settings that can get stuck in the "off" position.

Steps:

System Settings > Privacy & Security > Accessibility
Look for any clipboard-related toggles
Toggle off, wait 10 seconds, toggle back on
Restart your Mac

5. Check for Conflicting Apps

Third-party clipboard managers, screenshot tools, or automation software can conflict with the native clipboard, especially if they're outdated or incompatible with your macOS version.

What to do:

Temporarily disable clipboard-related extensions in System Settings > General > Login Items
Restart and test copy-paste
Re-enable them one by one to identify the culprit
Update or uninstall the offending app

6. Restart the Finder and Dock

Sometimes the graphical layer handling clipboard UI gets corrupted without affecting the actual clipboard service.

In Terminal:

killall Finder
killall Dock

Both will restart automatically. Your open windows may rearrange slightly, but this often restores clipboard visibility and responsiveness.

7. Factory Reset NVRAM/SMC

If none of the above work, a deeper hardware-level reset may be necessary. This clears low-level settings that can affect clipboard behavior.

For Intel Macs:

Shut down completely
Power on and immediately press and hold Command + Option + P + R
Hold until you hear the startup sound twice (or Apple logo appears and disappears twice)
Release and let your Mac start normally

For Apple Silicon Macs (M1/M2/M3):

Shut down completely
Press and hold the power button for 10 seconds
Release, wait a few seconds, then power on normally
Your SMC will reset automatically

How to Prevent Clipboard Issues: Use the Right Tool
