Moving file between disks in Mac OS X? 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?
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
