Is there any way so when I drag and drop a file from one disk(A) to another disk(B) the files are moved instead of copied? I have a mac book pro and a mac pro(old cool one) and when I drag and drop files they get copied instead of moved. So could I do some automate script or terminal command to enable move files from disk to disk instead of coping them?

  • My bad that is a typo, is plural so i can move files from disk to disk that are inside my machines. – jycr753 Sep 17 '14 at 12:48

On macOS Mojave 10.14:

To move files to a different disk: Press and hold the Command key, then drag the files to the disk.

To keep an item in its original location and put a copy in a folder: Press and hold the Option key, then drag the item to the folder.

In older macOS releases, you could press the option key to change the behaviour

  • move instead of copy between different volumes
  • copy instead of move on the same volume

    that works great, didn't knot existed. thanks, but is there any way to always say move instead of copy when the volumes are /dev/disk2 && /dev/disk3s2 – jycr753 Sep 17 '14 at 12:59
  • maybe a automator or command like to change the settings in the kernel? – jycr753 Sep 17 '14 at 13:18

Hold the "Command" key down, not the "option" key, while dragging your file between hard drives. You will know that you have done it correctly because the progress bar will say "moving" instead of "copying"
