Thanks for filing the issue!

@Reporter: Could you please mention the chrome version in which the issue is seen. Any further inputs from your end may help us to triage the issue in a better way.

I have also been experiencing very unreliable pasting behavior in Chrome 64.0.3282.186 (Official Build) (64-bit) on Mac OS X 10.13.2. It has been unreliable when pasting images from any app for many months now, but usually I could get it to work in some round-about way. Now, however, I'm finding that (as the OP says) even text copied from other apps isn't pastable in Chrome. For example, right this moment, Chrome is maintaining its view of my clipboard contents as "agreed" (a random word I copied from within Chrome for testing), whereas the rest of the OS views the contents of the clipboard as "hasattr", which I can successfully paste into all of my other apps (except for iTerm, interestingly, which has its own separate opinion about the clipboard at the moment as well, containing neither "agreed" nor "hasattr", but instead a file name I had copied earlier -- perhaps Chrome and iTerm on OS X are using the same apis for managing and accessing clipboard content, and those apis are unreliable?).

Anyway, this is severely detrimental to my ability to use Chrome. Please let me know what additional details or logs I can provide that will improve your ability to look into this issue.

#3: thanks for the report.

Can you repro this with a current Chrome version on a current macOS version?

At the moment, copy and paste is working for me on Version 65.0.3325.181 (Official Build) (64-bit) and OS X 10.13.2 (17C88). I will update the bug report if I find that it happens again.

Is there anything additional that you would like me to report if I do hit this issue again?

This is still happening periodically on a Mac running macOS High Sierra version 10.13.3 and Chrome Version 65.0.3325.181 (Official Build) (64-bit). 

Thank you for providing more feedback. Adding the requester to the cc list.

This may be the same as  issue 755116 

If it occurs, try running this in a terminal window:

launchctl list | grep com.apple.pboard

If the process does not exist, run:

launctl start com.apple.pboard

If it does exist, restart it with:

launctl stop com.apple.pboard
launctl start com.apple.pboard

... and then restart Chrome to attach to the process.

If this is the case, you're running into what we believe is an OS bug where the pasteboard service crashes. This affects multiple applications.

Marking as Needs-Feedback pending confirmation that this is the issue.

That seems very likely to be the case for some of the behavior I've seen. I'll try those steps next time I observe it.

There is another case that I see occasionally, including yesterday, which doesn't seem to fit quite as well, although it still seems likely to be an os-level issue. I was attempting to copy two urls from chrome tabs into a chrome text box. The first url copied fine. However, the second url would not copy/paste. After copying, the clipboard buffer was always empty. I was able to copy and paste smaller chunks of text from the web page without an issue, so the pboard process did not appear to have crashed. My belief at the time was that somehow the url had exceeded some length limit, as it had a long data parameter in it. I am no longer convinced that that is the case, though, as I was just able to copy/paste a url from the same page which should be similarly long, and it really isn't that long:

I was finally able to follow your instructions after hitting this issue. pboard was running for me, but stopping and starting it allowed me to recover the ability to copy and paste between apps. Is there an Apple bug report that I could +1 somewhere?
