Command C and Command V stopped working MacOS Mojave

Test:

- in a new user account

- in your account, while booted in Safe Mode

What happens?

Also, do you have any program that may intercept user input - e.g. Keyboard Maestro, Alfred, ...?

Try removing your login items;

Finally, run the diagnostic tool Etrecheck and post its report here.

We know nothing about your mac, which model, what software it is running...

These problems are always caused by a software conflict.

Command V works on guest account account but not mine. I can't find the problem software.

Only menu paste option works. Attached report.http://mudmangr@yahoo.com

Some of the programs that you are running in your account are probably causing this. To confirm, start in Safe Mode and see if command-C and command-V work (they almost certainly do).

You have a lot of old stuff. You still have "startup items", which do not work since Yosemite (10.10).
