Even though you have to get the paid version to really experience how great it is, it truly is fantastic. I like airdroid in certain circumstances, but for backing up files, Solid Explorer is a much better and more reliable option.
Solid Explorer allows you to set up a ftp link, which you input into your Mac's file explorer program, and you would transfer items over wirelessly...as if your phone were connected to your Mac via USB as a storage drive.

Once you've downloaded the app, this is how you get to the file sharing through the app:
On the phone
Connect to Wifi>Open Solid Explorer>Menu>File Sharing>Enter Password of your choice>Press Start (at bottom of screen)
On your mac
Open the file explorer program on your Mac>type in the Server Address showing on your Solid Explorer app>When pop-up window comes up, enter in the password you selected (username stays as admin)
Once you've done that, you should be able to see the directory for your internal and external storage. You can transfer files from your Mac to your phone and vice versa, until you press "Stop" on the Solid Explorer app.
I'm not rooted (...I can hear the groans from the vets on this forum as I typed that...LOL).
