How to Access Android files on Mac

I recently purchased a Nexus 4 phone, over the past couple of months I have been taking photos and video and wanted to transfer them to my iMac. I thought I would simply need to plug in the phone into the USB port and it would see the files, this is how it is done on Windows PC. At first I was a bit worried that because it was not Apple, and I had an awful feeling it would not work. But after doing some research all you need to do is download the Android File Transfer application, install it and you can see the files on your Nexus 4 phone.
