Mac-The operation can’t be completed because an unexpected error occurred.

Sometimes mac has a problem while deleting or copying a file .If we trash finder preferences (~/Library/Preferences/com.apple.finder.plist) it fixes the things. Unfortunately Apple hides your library folder now so you need to:

  3. Click on the “Go” menu
  4. Select “Library” (hidden if the option key is not down)
  5. locate the folder “Preferences”
  6. locate the file “com.apple.finder.plist”
  7. move said file to trash
  8. log out
  9. log in
  10. test to see if fixed
