[Fixed] Copy and Paste Not Working on macOS Mojave

 
 

Overview: Copy & Paste is one of the most used features in any Mac or PC. Imagine, when this feature does not work, how annoying and frustrating this can be. Today in this article we will troubleshoot Copy and Paste issue on Mac. Troubleshooting applies to all macOS.

Let’s Start with Few Practical Scenarios

Scenario 1: Copy/Paste Stopped Working

Everything was working yesterday. Started working on my computer today but the copy/paste feature is not working. I had this problem a while back on my laptop MacOS Mojave. Fixed the laptop by installing an update. Checked for updates on High Sierra but there is nothing available. Now I do not know how to fix it. I tried stopping the pboard on the activity monitor but that did not work either.

Scenario 2: iMac with Mojave 10.14.3 Copy and Paste Problem.

Using the mouse cursor, wanting to copy a section of text, there is no shadow beneath the text, yet by eyeball placing of the cursor, I am able to extract the text I want.  I have run the Activity Monitor “pboard” “force quit” routine as suggested to solve this problem, but to no avail.  I have also reloaded Mojave, but still, have the same problem.  Because there is no underlying “shadow” beneath the text it is difficult to know you are extracting the exact text you were hoping for.  For instance, on this very message, I get no shadow when I try to copy a portion of what we are looking at. Any suggestions welcome.
