I recently upgraded my machine to macOS Sierra. In the last couple of days I've noticed that cutting and pasting is increasingly flakey. I thought initially that copy wasn't working since I didn't seem to be able to copy new content to the clipboard, but after trying various things I now have my machine in a state where Cmd-V or pasting via the Edit menu produces a different result to pbpaste. Are there any circumstances under which this would be expected?

I'm not sure how to diagnose this. In another similar question I saw a request for the output of kextstat | grep -v com.apple, which I've added below.

I'll probably have to restart my machine now since I really need to get work done, but any suggestions for when this happens again would be gratefully received.

  • Perhaps you could link to the ‘similar question’ you found? – grg Feb 9 '17 at 8:57
  • Sierra (and iOS 10) introduced the universal clipboard, which I'm guessing also introduced a few bugs. Are you signed into iCloud, with iOS devices nearby? Does signing out of iCloud help? – calum_b Feb 9 '17 at 17:27
  • @grgarside Good idea, done, thanks. The issue related but not that similar, but several commenters asked for this information to help diagnose it. – Colin Feb 10 '17 at 9:51
  • @calum_b Thanks for the suggestion, I'll definitely try that next time this occurs. – Colin Feb 10 '17 at 9:52
