Usually we try to give the command Ctrl + X for cut instead of Ctrl + C while (copying or trying to cut from the source directory / folder)

But in Mac, this command is specified at the time we paste to the target, meaning : while doing copy or cut from source, its always copy : Command + C

But while pasting, it differs, it should be : 

(If the intension is cut) : Command + Alt (Option) + V (It means after pasting to destination, it will remove from source path)

(If the intension is copy) : Command + V
