If you have been using OS X to manage your files on your Macbook, you can try out the Commander One app which is an alternative for the OS X. Also a file management tool, the Commander One by Eltima offers a convenient dual panel mode to let you create, delete, copy, and move files and folders easily.
The Commander One opens to display its main dual pane file explorer window.
Folders from each device can be seen arranged in two separate panels side-by-side on the Commander One window. This allows you to drag and drop folders easily between the Apple MacBook (Early 2015) and the LG G5. We successfully perform a quick transfer of a 270 MB movie file from the Macbook over to the phone.
