cmd + c and cmd + x not work properly

Dear Genius,

since long time after upgraded to high Sierra, my copy and cut shorcuts do not work properly. Often it need be registered twice or even more times. Otherwise, the pasted content remains the last copied or cut content. This is really annoying.

Do you have some idea?

Best Regards,

Hello duckcudente,

Thanks for asking the Apple Support Communities for help with Copy and Paste on your Mac. I am happy to check this out with you.

First, I would like to rule out the keyboard as the issue. Do you have a keyboard you can connect to the Mac and test with? A wired or bluetooth keyboard can be used. If the issue is not occurring with other keyboards, we know the issue is with the built in keyboard. I recommend having the computer checked at an Apple Authorized Service Provider or Apple Store. Use this link to find a service provider in your area: Apple - Find Locations

If not, we can test this in Recovery. This article talks about Recovery: About macOS Recovery - Apple Support

Hold down Command-R or one of the other macOS Recovery key combinations on your keyboard immediately after pressing the power button to turn on your Mac, or immediately after your Mac begins to restart. Continue holding until you see the Apple logo or a spinning globe. Startup is complete when you see the utilities window:

Once there, use the third option to "Get Help Online" and test if you can use Copy and Paste in the URL bar here. If it does not work as expected in recovery, I recommend having the keyboard hardware checked. The link above can help you find a service provider.

If it is working properly in Recovery, this means your keyboard is working properly. I recommend trying this in safe mode and a test user. Safe mode will tell us if the issue is related to a startup item or plugins, and sometimes is all that is necessary to correct some problems.

When you boot to safe mode, log in to your account and check if the issue is also occurring in safe mode or not. Use this article for the steps to get into safe mode: Use safe mode to isolate issues with your Mac

If everything is working properly in safe mode, but then is not working after you restart the Mac, please check the section titled "If an issue doesn't happen in safe mode" for the next troubleshooting steps.

If the issue is also happening in safe mode, move on and test if this problem occurs in a newly created unmodified test administrator user account on your Mac. A test user will let us know if the issue is isolated to your account, or system wide. Please check this help article: How to test an issue in another user account on your Mac

After you are done testing, please check the section related to results, titled "If the issue happens in the other account" or "If the issue doesn't happen in the other account”.

Thanks again and have a great rest of your day.
