Virtualbox Kali Bridged Connection Issue

Hey guys, I want to use the Bridged Connection Option with Kali 1.1.0a in Virtualbox. I am currently utilizing a Macbook Pro (Early 2011 Model) running OSX El Capitan. The version of Virtualbox installed on my Mac is 5.0.12 r104815. I have done a lot of different tests to try to pinpoint the issue, including:

• Reinstalling Virtualbox (FAILED)
• Installing an Older Version of Virtualbox (FAILED)
• Posting on the Virtualbox Forums (No Answer After Over a Week)
• Trying the Same Tests on my Bootcamp Install of Windows 7 (FAILED)
• Making Use of a Ethernet Cable Bridged Connection (WORKED)

From my research online this seems to be a recurring issue with a lot of people. I don't really want to be confined to constantly using a ethernet cable every time I want to interact with the local network, so any help here would be much appreciated!
