I already tried:

  1. Force quit Finder
  2. sudo launchctl start/stop com.apple.pboard
  3. System Preferences> Keyboard> Modifier Keys > Restore Defaults
  4. System Preferences> Shortcuts> App Shortcuts> + (when I tried to write the shortcut in "Keyboard Shortcut" Command C doesnt work)

When I try to paste it's ok, it works. The problem is to copy, the shortcut doesnt work and the edit flash doesnt work too. Its the same with Shift + e

The keys Command, Shift, C and e work separately. They dont work like shortcuts

Model: Macmini6,1

    If it used to work, sounds like a hardware issue with the keyboard. Update your question with the Mac model or keyboard you are using. Cheers

  • Is Command C the shortcut for Copy, as shown in the Edit menu? If it is, and the keys all work separately -- and you've rebooted -- then I would suspect a hardware problem. Have/Can you try another keyboard?

Go to System Preferences and click on the keyboard. A panel opens with 5 tabs at the top. Click on the Keyboard Tab and a new panel appears.

In this panel click on the button at the bottom which says "Modifier Keys". This brings up a menu on the previous panel. See image below.

you can define what the command key actually is. Make sure the command key is defined as the Command key.
