Paste stops working ("CFPasteboardRef: Lock timeout") Pasting from the clipboard stopped working on my Mac. Nothing is pasted, and the following line appears many time in syslog.

Apr  5 **:**:** *** com.apple.WebKit.WebContent[6583] &lt;Warning&gt;: CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : Lock timeout


This seems related to a clipboard tool I installed ("FlyCut"), but I have since uninstalled. I can see no running process related to the tool (using ps -ef).

Rebooting temporarily solves the problem. Is this a virus? At any rate, how do I get rid of the problem? Found nothing of value searching for the log message. Malwarebytes reports nothing.

Update: Reported the issue to Apple, and they said it was caused by an app called "Time Out". They are still working to resolve the problem. In the meantime, uninstall this app.
Doesn't appear to be malware for me.

The workaround (though totally crappy) is:


Launch Activity Monitor
Find pboard process and quit the process.
Restart applications where you would like to copy from or paste into.
